Transcript of What is plastic
What is plastic?Plastic is the general common term for a wide range of synthetic or semi-synthetic materials used in a huge, and growing, range of applications from packaging to buildings; from cars to medical devices, toys, clothes etc.
The term ‘’plastic’’ is derived from the Greek word ''plastikos'' meaning fit for moulding, and ''plastos'' meaning moulded. It refers to the material’s malleability, or plasticity during manufacture, that allows it to be cast, pressed, or extruded into a variety of shapes - such as films, fibres, plates, tubes, bottles, boxes, and much more.
There are two broad categories of plastic materials: thermoplastics and thermosetting plastics. Thermoplastics can be heated up to form products and then if these end products are re-heated, the plastic will soften and melt again. In contrast, thermoset plastics can be melted and formed, but once they take shape after they have solidified, they stay solid and, unlike thermoplastics cannot be remelted.
HistoryHow plastic is made
Plastics are derived from organic products. The materials used in the production of plastics are natural products such as cellulose,
coal, natural gas, salt and, of course, crude oil.
Crude oil is a complex mixture of thousands of compounds. To become useful, it must be processed.
The production of plastic begins with a distillation process in an oil refinery
The distillation process involves the separation of heavy crude oil into lighter groups called fractions. Each fraction is a mixture of
hydrocarbon chains (chemical compounds made up of carbon and hydrogen), which differ in terms of the size and structure of
their molecules. One of these fractions, naphtha, is the crucial element for the production of plastics.
The two major processes used to produce plastics are called polymerisation and polycondensation, and they both require specific
catalysts. In a polymerisation reactor, monomers like ethylene and propylene are linked together to form long polymers chains.
Each polymer has its own properties, structure and size depending on the various types of basic monomers used.
There are many different types of plastics, and they can be grouped into two main polymer families:
Thermoplastics (which soften on heating and then harden again on cooling)
Thermosets (which never soften when they have been moulded)
Examples of ThermoplasticsAcrylonitrile butadiene styrene – ABSPolycarbonate - PCPolyethylene - PEPolyethylene terephthalate - PETPoly(vinyl chloride) - PVC
Examples of ThermosetsEpoxide (EP)Phenol-formaldehyde (PF)Polyurethane (PUR)Polytetrafluoroethylene - PTFE
Poly(methyl methacrylate) - PMMAPolypropylene - PPPolystyrene - PSExpanded Polystyrene - EPS
Unsaturated polyester resins (UP)
Types of plastics
Everywhere you look you will find plastics. We use plastic products to help make our lives cleaner, easier, safer and more
enjoyable. You will find plastics in the clothes we wear, the houses we live in, and the cars we travel in. The toys we play with, the
televisions we watch, the computers we use and the CDs we listen to contain plastics. Even the toothbrush you use every day
contains plastics!
Plastics are organic, the same as wood, paper or wool. The raw materials for plastics production are natural products such as
cellulose, coal, natural gas, salt and, of course, crude oil. Plastics are today’s and tomorrow’s materials of choice because they
make it possible to balance modern day needs with environmental concerns.
The plastics family is quite diverse, and includes:
ABS/SAN
Epoxy resins
Expandable Polystyrene
Fluoropolymers
PET
Polycarbonate
Polyolefins
Polystyrene
PVC
PVdC
Styrenic polymers
Unsaturated Polyester Resins (UPR)
All these types of plastics can can be grouped into two main polymer families: Thermoplastics, which soften on heating and
then harden again on cooling, and Thermosets which never soften when they have been moulded.
Examples of Thermoplastics
Acrylonitrile butadiene styrene – ABS
Polycarbonate - PC
Polyethylene - PE
Polyethylene terephthalate - PET
Poly(vinyl chloride) - PVC
Poly(methyl methacrylate) - PMMA
Polypropylene - PP
Polystyrene - PS
Expanded Polystyrene - EPS
Examples of Thermosets
Epoxide (EP)
Phenol-formaldehyde (PF)
Polyurethane (PUR)
Polytetrafluoroethylene - PTFE
Unsaturated polyester resins (UP)
A range of additives are used to enhance the natural properties of the different types of plastics - to soften them, colour them,
make them more processable or longer lasting. Today not only are there are many, many different types of plastic , but products
can be made rigid or flexible, opaque, transparent, or coloured; insulating or conducting; fire-resistant etc., through the use of
additives.
Over 100 years of plastics
Humankind worked hard from the earliest times to develop materials which would offer benefits not found in
natural products. The development of plastic materials started with the use of natural materials with plastic
properties (e.g., chewing gum, shellac) then evolved with the development of chemically modified natural
materials (e.g., rubber, nitrocellulose, collagen, galalite) and finally the wide range of completely synthetic
material that we would recognise as modern plastics started to be developed around 100 years ago. Perhaps the
earliest example was invented by Alexander Parkes in 1855. We know it today as celluloid, but he named it Parkesine. Polyvinyl
chloride (PVC) was first polymerised between 1838-1872 and a key breakthrough came in 1907 when Leo Baekeland created
Bakelite, the first real synthetic, mass-produced plastic.
ABS/SANThe terms Styrenics or Styrenic Polymers are used to describe a family of major plastic products that use Styrene as their key
building block. Included in this family of products are:
ABS, or Acrylonitrile Butadiene Styrene Copolymer: an opaque, thermoplastic polymer material made from
the monomers Acrylonitrile, 1,3-Butadiene and Styrene. Strong and durable even at low temperatures, it
offers good resistance to heat and chemicals and is easy to process.
SAN - Styrene Acrylonitrile Copolymer: a transparent thermoplastic polymer material with amorphous
structure made from the monomers Styrene and Acrylonitrile.
PS, or Polystyrene: a thermoplastic polymer which softens when heated and can be converted into semi-finished products
like films and sheets, as well as a wide range of finished articles.
EPS, or Expandable Polystyrene: a thermoplastic product that is lightweight, strong, and offers excellent thermal
insulation, making it ideal for the packaging and construction industries.
UPR, or Unsaturated Polyester Resins: durable, resinous polymers derived from styrene and used mainly the construction,
boat building, automotive and electrical industries.
SBR, or Styrene Butadiene Rubber: a rubber manufactured from styrene.
The benefits of styrenic polymers
Styrenic polymers offer many industries a wide variety of benefits, including:
lightweight, water resistant and excellent thermal insulator characteristics
in food packaging, they provide high levels of protection against spoilage
Rigid, with a high strength-to-weight ratio that offers energy-savings benefits in transportation and an excellent cost
performance
Can be shatterproof and transparent if required
Good electrical insulation
Easy to process and produce in a range of attractive colours
Easy to recycle
Manufacturers use styrene-based resins to produce a wide variety of everyday goods ranging from cups and utensils to furniture, bathroom, and kitchen appliances, hospital and school supplies, boats, sports and recreational equipment, consumer electronics, automobile parts, and durable lightweight packaging of all kinds.

The market for ABS/SANThe market for ABS/SANABS market applications
Is ABS a widely used plastics?
Clearly, YES. ABS is a very versatile material and therefore very popular among designers. It is scratchproof, highly resistant,
dimensionally stable, glossy and easy to colour. Therefore, ABS is used in a broad variety of applications in everyday life like
housings for vacuum cleaners, kitchen appliances, telephones and toys. Other important fields of applications for ABS are the
automotive industry and the electrical/electronics (E/E) segment – here primarily in white goods and computer/communication
electronics.
How large is the market for ABS?
Within the group of styrene co-polymers, ABS is by far the biggest product line in terms of volume. Last year’s global consumption
was about 5.4 million tons. It is expected that ABS will continue to show above average growth rates. Until 2010 the average
annual growth rate is estimated at 5.5%.
For Europe, it is expected that ABS consumption will rise from its present 750,000 tons to 800,000 tons within the next five years.
Automotive, appliances and E/E account for almost 50% of European ABS consumption.
SAN market applications
Is SAN a widely used plastic?
Even though SAN is much smaller in terms of volume compared to polystyrene or ABS it is widely used in a great variety of
different applications. The outstanding transparency combined with good chemical resistance, stability in dishwashers, high
impact strength, thermal shock resistance and stiffness make SAN the preferred material for manufacturers of consumer goods.
High quality household appliances and top-quality packaging for cosmetics are examples for SAN products.
How large is the market for SAN?
The European SAN consumption is roughly 125.000 tons per annum. The main industry sectors are household, cosmetics, sanitary
and toiletry, electronics as well as outdoor industrial applications.
How are ABS/SAN manufactured? How are ABS and SAN made...and processed?ABS is made by emulsion or continuous mass technique. Globally, the most important is the emulsion process. It is a two-step
method in which the ABS rubber component is produced in emulsion and afterwards combined with SAN on suitable melt mixing
aggregates like extruders or kneaders. The SAN available on the market nowadays is almost exclusively manufactured by the
mass process. The final product is available in the form of pellets.
ABS can be processed by injection moulding or extrusion technique. SAN is mainly processed by injection moulding.

Epoxy resins
Epoxy resins have been around for over 50 years, and are one of the most
successful of the plastics families. Their physical state can be changed from a low
viscosity liquid to a high melting point solid, which means that a wide range of
materials with unique properties can be made. In the home, you’ll find them in soft-
drinks cans and special packaging, where they are used as a lining to protect the
contents and to keep the flavour in. They are also used as a protective coating on
everything from beds, garden chairs, office and hospital furniture, to supermarket
trolleys and bicycles! Most industries use them in protective coating materials. They are used, for example, in special paints to
protect the surfaces of ships and oil rigs from bad weather and also in wind turbines!
Benefits of epoxy resins
As a family of synthetic resins, their physical state can be anything from a low viscosity liquid to a high melting point solid. 'Cross-
linked' with a variety of curing agents or hardeners, they form a range of materials with a unique combination of properties, which
make a considerable contribution to practically every major industry, including:
Aircraft and aerospace
Automotive
Construction and heavy engineering
Chemical
Electrical
Electronic
Food and beverage
Marine

The market for EPSIs EPS a widely used plastic?
Yes. EPS is among the biggest commodity polymers produced in the world. The total world demand in 2001 was 3.06 million tons
and is expected to grow at 6 percent per year. EPS is a solid foam with a unique combination of characteristics, like lightness,
insulation properties, durability and an excellent processability. EPS is used in many applications like thermal insulation board in
buildings, packaging, cushioning of valuable goods and food packaging.
How large is the European market for EPS?
Western Europe contributes 27 percent of the global demand for EPS and was approximately 840 ktons in 2001. The
corresponding value of this volume is approximately 3 billion Euro. The average annual growth is expected to be 2.5 percent per
annum up to 2010.
The pie chart demonstrates the main EPS market applications for Europe. The major applications are building / insulation and
packaging.
Insulation with EPS provides safe installation and affordable access to energy reduction in heating and cooling buildings.
Packaging is also considered an essential final application of EPS, where it supplies lightness and protects health by reducing
spoilage of the product. The use of plastic packaging in general and of suitable insulating materials like EPS, together with
freezing technology means that only 2 percent of the food is spoiled in the West, while this is up to approximately 50 percent in
the developing countries.
Applications overviewMain EPS market applications for Europe
Building & Insulation applications
EPS resins are among the most popular materials for building and construction applications. EPS insulation foam
are used in closed cavity walls, roofs, floor insulation and more. With its excellent price/performance ratio EPS is
also used in pontoons and road construction. In addition to its traditional insulation application in the construction
industry, EPS foam also finds a wide use in civil engineering and building: road foundations, void forming,
flotation, drainage, impact sound insulation, modular construction elements, cellular bricks, etc. They all exploit the excellent
mechanical properties of EPS combined with fast construction / assembly and low subsequent maintenance.
Packaging applications
Eggs, meat, fish and poultry. Cold drinks or carry-out meals. All these products are safely packed with EPS
packaging materials; by doing so spoilage of foods is prevented. In the western world a combination of good
packaging, refrigeration and transportation ensures that only two percent of food is lost through spoilage,
compared with 50 percent in developing countries.
No matter what your products package, EPS have long been recognized as a versatile and cost-effective
solution for foods and goods packaging.
Expensive TV's and all kind of IT equipment travel safely from the production line to the consumer's houses.
EPS is the leading choice for electronic goods cushioning.
Other applications
Apart from the typical application in construction and packaging, EPS protective qualities can also be used in crash helmets -
protecting the heads and potentially the lives of cyclists, or into surface and other decoration ranging from simple printing of a
brand name to an elaborate pictorial representation achieved by mould engraving, or for fun and sports with e.g. windsurfing
board.
How are EPS made ... and processed?The building block - monomer - of polystyrene is styrene. The raw materials to make styrene are obtained from crude oil. A range
of processes such as distillation, steam-cracking and dehydration are required to transform the crude oil into styrene. At the end
polystyrene is produced by polymerising styrene. During polymerisation pentane is added as foaming agent.. The final product is
available in the form of spherical beads. Before being formed into the final article, the EPS beads need to be processed. When
these expandable pearls are heated with steam, they expand to about 40 times their original size. After a stabilisation period -
maturing - the expanded beads are then transferred to a mould. Further steam-heating makes them fuse together to form a rigid
foam containing 98% air. When and where needed, the foam can then easily be cut into the desired shape.
Styrenics polymers
The terms Styrenics or Styrenic Polymers are used to describe a family of major plastic products that use Styrene as their key

The market for PSIs polystyrene a widely used plastic?
The answer is a simple YES. Polystyrene is the fourth biggest polymer produced in the world after polyethylene, polyvinyl chloride
and polypropylene. The total demand in 2001 was 10.6 million tons. The corresponding value of this volume is approximately 10
billion euro.
General purpose polystyrene (GPPS) is a glasslike polymer with a high processability. When modified with rubber it results in a
high impact polystyrene (HIPS) with a unique combination of characteristics, like toughness, gloss, durability and an excellent
processability. Polystyrene is one of the most versatile plastics. Both forms are used in a wide range of applications like consumer
electronics, refrigeration, appliances, housewares, toys, packaging, disposables and medical and pharmaceutical.
How large is the global market for polystyrene?
The global market for polystyrene is 10.6 million tons and is expected to grow at 4 percent per year to approximately 15 million
tons in 2010.
How large is the European market for polystyrene?
Europe contributes 26 percent to the global demand for polystyrene and was approximately 2.7 million tons in 2001. Although the
average annual growth is expected to be 3-4 percent per annum up to 2010, the actual annual growth in Europe is 4-5 percent,
slightly ahead of the GDP.
The pie chart demonstrates the main polystyrene market applications for Europe. The major part is in packaging applications, like
dairy products. Packaging is an essential feature of the supply chain operations, which bring the product from the initial
manufacture to its ultimate use by the consumer. For the consumer convenience and easy opening are important elements, for
society as a whole, the biggest advantage is the prevention of spoilage of the product. Only 2 percent of the food is spoiled in
developed countries West, while this is up to approximately 50 percent in the developing countries.

to blenders, polystyrene resins meet almost all end-product requirements. Polystyrene resins are
safe and cost effective, with excellent appearance and functionality mainly due to easy-processing.
Because of this almost 26 percent of the polystyrene demand is used in injection-molding, extrusion
and thermoforming applications.
Polystyrene applications - consumer electronics
Polystyrene is used for housing for TV's and all kind of emerging trends in IT equipment where the critieria for use
are combinations of function, form and aesthetics and a high performance/cost ratio. Polystyrene is the leading
choice for media enclosures, cassette tape housing and clear jewel boxes to protect CD's and DVD's.
Polystyrene applications - construction
Polystyrene resins are among the most popular materials for building and construction
applications, like Insulation foam, roofing, siding, panels, bath and shower units, lighting, plumbing
fixtures. With their excellent price performance balance and good processability and other
performance properties, polystyrene resins find use in these building products.
Polystyrene applications - medical
Bringing new and improved medical technologies to patients and physicians is a complex, regulated process.
With excellent clarity and processability and outstanding post-sterilization aesthetics, polystyrene resins are
used for a wide range of disposable medical applications, including tissue culture trays, test tubes, petri
dishes, diagnostic components, and housing for test kits.
Polystyrene applications - other
As well as the traditional uses for polystyrene, a variety of consumer goods applications, including toys,
electric lawn and garden equipment, kitchen and bath accessories and other durable goods are made from
polystyrene. Polystyrene resins have an excellent cost/performance ratio, and in many cases, can be substituted for more costly
polymers.
What is inside the polymer?Styrene is the primary raw material from which polystyrene (PS) - being general purpose (GPPS) or high impact (HIPS) or
expandable polystyrene (EPS) - is made. GPPS - is a polymer of styrene only, whereas high impact polystyrene in particular is a
copolymer of styrene and polybutadiene synthetic rubber. Often some lubricant - mineral oil - is added to polystyrene to
improve the processability. In order to control the fire characteristics an aliphatic brominated compound or other flame
retardant is added to respectively produce FR-EPS or FR-HIPS. Polystyrene foam and EPS are manufactured with the use of a
blowing agent. Primarily a mixture of pentanes is used, but also carbon dioxide can be employed.
Styrene
Styrene is a clear, colourless liquid that is derived from petroleum and natural gas by-product, but which also occurs naturally. It
is present in many foods and beverages, including wheat, beef, strawberries, peanuts and coffee beans. Synthetic styrene played
an important role during World War II in the production of synthetic rubber. After the war the demand for synthetic rubber
decreased and polystyrene was an obvious alternative. Today roughly 3 million tonnes of polystyrene are produced, ranking it the
fourth among the commodity plastics behind polyethylene, polypropylene and vinyl polymers. Styrene helps create several plastic
materials used in thousands of remarkably strong, flexible, and lightweight products, that represent a vital part of our health and
well being. It's used in everything from food containers and packaging materials to cars, boats, and computers.
Synthetic rubber
Rubber occurs naturally, obtained from the exudations of certain tropical trees; in Indian language it was called "Cahuchu" – tears
of the wood. From Cahuchu it is easy to understand the German "Kautschuk". Synthetic rubber is derived from petroleum and
natural gas. The first synthetically produced rubbers were derived from isoprene and styrene butadiene. Later 1,4-polybutadiene
was introduced using the Ziegler Natta procede catalysis. These polybutadiene rubbers are used in the manufacture of toughened
polystyrene. Unmodified polystyrene (GPPS) offers poor impact resistance and breaks easily, dispersions of up 10 %
polybutadiene rubber into polystyrene yields a high impact resistant product (HIPS).
Mineral oil
White mineral oil is added to polystyrene as lubricant to improve the processing properties. White mineral oil has a paraffinic
nature and is approved by the European Union as additive to be used in plastics that come in contact with foods, when it meets
certain specifications.
Aliphatic brominated compounds
Aliphatic brominated flame retardant additives are often added during the polymerisation of styrene into expandable polystyrene.
These compounds significantly improve the fire behaviour of EPS used in non-food contact applications. Where or whenever this
aliphatic brominated additive is handled during production sufficient and adequate measures are taken to prevent release and
exposure: extraction devices equipped with filters or cyclones, wastewater treatment units, etc.
Other fire retardants
Polystyrene is a combustible material. Because of its extremely good processability polystyrene is an excellent material for
certain electrical and electronic applications. In order to prevent fire and save lives these applications must meet strict fire safety
standards. These standards can only be met by adding a flame retardant additive system, usually a brominated substance.
Pentane
Extended polystyrene foam and expandable polystyrene beads contain a pentane as blowing agent. The relatively small amount
present is gradually but quickly eliminated to the atmosphere through the different steps of processing. Nevertheless, measures
are to be taken to avoid the formation of the explosive air-pentane mixture and to limit emissions in manufacture. With ever
evolving technology, some manufacturers of extruded polystyrene – XPS for short - packaging foam use the natural occurring gas
carbon dioxide (CO2) as a blowing agent.
What is inside the Copolymers?What is inside the Copolymers?
Beside Styrene and polybutadiene synthetic rubber. Acrynolitrile the third monomer component of ABS and SAN. In
addition, both copolymers usually contain approved additives like thermal stabilizers, mould release and flow agents. Light
stabilizer /UV stabilizer are used if better weatherability is required. High modulus materials can be obtained by adding of glass
fibres. For ABS, bromine compounds are employed as flame retardants.
Styrene
Styrene is a clear, colourless liquid that is derived from petroleum and natural gas by-product, but which also occurs naturally. It
is present in many foods and beverages, including wheat, beef, strawberries, peanuts and coffee beans. Synthetic styrene played
an important role during World War II in the production of synthetic rubber. After the war the demand for synthetic rubber
decreased and polystyrene was an obvious alternative. Today roughly 3 million tonnes of polystyrene are produced, ranking it the
fourth among the commodity plastics behind polyethylene, polypropylene and vinyl polymers. Styrene helps create several plastic
materials used in thousands of remarkably strong, flexible, and lightweight products, that represent a vital part of our health and
well being. It's used in everything from food containers and packaging materials to cars, boats, and computers.

polystyrene. Unmodified polystyrene (GPPS) offers poor impact resistance and breaks easily, dispersions of up 10 %
polybutadiene rubber into polystyrene yields a high impact resistant product (HIPS).
Acrylonitrile
Acrylonitrile is a man-made colourless to pale yellow liquid of significant volatility (boiling temperature of 78°C) and sharp odour.
It is soluble in water and many common organic solvents. Acrylonitrile is of high reactivity thus polymerizing spontaneously when
heated.
Acrylonitrile is produced commercially by oxidation of propylene together with ammonia. It is used mainly as a co-monomer in the
production of acrylic fibers. Uses include the production of plastics, surface coatings, nitrile elastomers, barrier resins, and
adhesives. Worldwide consumption of Acrylonitrile exceeds 4 million tons p.a.
Main use of Acrylonitrile in plastics is as a co-monomer in ABS and SAN. Its main contribution is increased chemical resistance,
toughness and heat resistance.
Fluoropolymers Fluoropolymers are a family of high-performance plastics. The best known member of this family is called PTFE. PTFE is one of the
smoothest materials around, and very tough! You can find it in most kitchens as a coating on pots, pans and many other utensils!
Fluoropolymers are also used to improve the performance and safety of racing cars and aircraft. They help protect big buildings
from fire. They can also be found in the coatings of the cabling for telephones and computers.
Fluoropolymers are polymers containing atoms of fluorine. The family includes two types of fluorinated thermoplastics:
Type one fluoropolymers are fully fluorinated, which means that all hydrogen atoms are replaced by fluorine atoms). Examples of
these include PFA/MFA and FEP. Type two fluoropolymers are only partially fluorinated. Examples of these include PVDF, ETFE,
and ECTFE.
Benefits of fluoropolymers
Fluoropolymers have many unique qualities, including great strength, versatility, durability, and an unusually high resistance to
chemicals (solvents, acids and bases) and heat. These qualities make fluoropolymers very versatile. They are used in:
High-performance automotive and aircraft bearings and seals, to improve the performance and safety of aircraft and
automobiles
Flame retardants, to reduce fire risk in high-rise buildings and reduce industrial and automotive pollution
Coatings on many kitchen products, such as pots, pans, knives, spatulas etc. thanks to their high thermal stability and
non-stick properties
The linings of piping and chemical tanks, and in packing for lithium-ion batteries, thanks to their ability to handle harsh
environments
Cable coating in the telecommunications and computer industries, because of their high electrical resistance and good
dielectric properties
Implantable parts and catheters for bio-medical applications, because of their resistance to chemicals
It is estimated that the world market for fluoropolymers is between 80,000 and 90,000 tons per year. Although fluoropolymers
represent just 0.1% of all plastics, their outstanding performance characteristics have made them a valuable catalyst in improving
the quality of our lives.

What are Fluoropolymers?Fluoropolymers are fluorinated plastics. Most plastics are chains of carbon atoms with hydrogen or other atoms attached to them.
In fluoropolymers, fluorine atoms replace some or all of the hydrogen atoms. Substituting fluorine for hydrogen creates a high
binding energy among atoms within the plastic molecules, making the plastics highly stable and giving them unique and valuable
properties. Fluoropolymers are in general more resistant to heat and chemical attack than other materials. They have strong
electrical insulation, lubrication, non-stick, temperature resistance, transparency, and other properties.
Different fluoropolymers have different properties. Type one fully fluorinated polymers, in which fluorine atoms replace all of the
hydrogen atoms generally emphasise the properties mentioned above.
Type two partially fluorinated polymers, in which fluorine atoms replace only some of the hydrogen atoms, are useful for
applications in which mechanical toughness greater than that available to fully fluorinated polymers is required, special
processing or manufacturing conditions are desirable or resistance to specific chemicals is useful.
Type one fluoropolymers. Examples of these are:
PFA/MFA, FEP
And type two fluoropolymers. Examples of these are:
PVDF, ETFE, ECTFE
PTFE
PTFE is a polymer consisting of recurring tetrafluoroethylene monomer units whose formula is [CF2-CF2]n. PTFE does not melt to form a liquid and cannot be melt extruded. On heating, the virgin resin coalesces to form a clear gel at 335°C+/-15°C. Once processed, the gel point (often referred to as the melting point) is 10°C lower than that of the virgin resin. PTFE is sold as a granular powder, a coagulated dispersion/fine powder, or an aqueous dispersion. Each is processed in a different manner.For nearly seven decades, PTFE has paved the way for technological advancement in many industries. Its properties include the lowest friction coefficient of any solid material in the world, extreme thermal and chemical resistance (essential in aircraft and spacecraft), and exceptional dielectric strength (LAN Cables). These unique qualities of PTFE have enabled researchers to break new ground and bring to life modern high-performance aircraft, pharmaceutical production methods, medical diagnostic and treatment instruments, telecommunications apparatus and wiring, computing gear, and semiconductor technology. In short, fluoropolymers
are crucial to everyday modern life as we have come to know it. Since PTFE is soft and, not being melt-processable, requires specialized manufacturing techniques.
FEPFEP fluorocarbon resin is a copolymer of tetrafluoroethylene and hexafluoropropylene with the formula [(CF(CF3 )-CF2)x(CF2-CF2)y ]n. It has a melting point range of 245°-280°C and is melt processable. It is supplied in the form of translucent pellets, powder or as an aqueous dispersion.FEP is a fluoropolymer with superior dielectric characteristics and low flammability, ideal for insulating plenum-rated LAN cables. Cables used in modern telecommunication and computing use ultrahigh-frequency signals (megahertz and gigahertz ranges). Such high frequencies exceed the capability of almost all materials to provide effective insulation. In addition, the practical use of such cables often requires running them for considerable distances without splices or other connections.PFA
PFA fluorocarbon resin is a copolymer of tetrafluoroethylene and a perfluorinated vinyl ether having the formula [(CF(ORf)-
CF2)x(CF2 -CF2 )y ]n where ORf represents a perfluoralkoxy group. PFA melts at 280°C minimum and is melt processable. Some
grades are chemically stabilised. It is available in the form of translucent pellets, powder, and as an aqueous dispersion.
MFA
MFA is a random copolymer of tetrafluoroethylene and perfluoromethylvinylether. It belongs to the generic class of PFA polymers.
MFA melts at 280° C. It is available in the form of translucent pellets and aqueous dispersions.
PFA & MFA
PFA & MFA fluoropolymers are generally suited to high-purity, low-contamination applications in corrosive environments and
certain grades of PFA and MFA are specially stabilised to work well in highly corrosive environments. Semiconductors with circuits
measured in nanometres, require freedom from contamination. Imperfections even at the submicroscopic level will render a
semiconductor useless. Pipes, valves, fittings, pumps, baths, and carriers used in wet processing must be chemically inert and not
leach into, react with, or release particles into the chemicals used to etch, clean or otherwise process raw silicon wafers, work-in-
process or finished semiconductors.
ETFE
Styrene's ETFE is a copolymer consisting mainly of ethylene and tetrafluoroethylene, having the formula [(CF2-CF2)x-(CH2- CH2)y
]n often modified with a small percentage of a third monomer. Depending on the molecular structure the melting range is 215°C
to 270°C. It is melt processable and is supplied in the form of pellets, powder and dispersions.
ECTFE
ECTFE is a copolymer of ethylene and chlorotrifluoroethylene having the formula (CH2 -CH2 )x -(CFCl-CF2)y]n . It is often modified
with a small percentage of a third monomer. Depending on the molecular structure, the melting range is 190-240°C. It is available
in the form of translucent pellets and as a fine powder.
ECTFE is a fluoropolymer that can be processed into films, and retains integrity when exposed to harsh chemicals and strong
polar solvents. This makes it suitable for water purification systems. Aggressive cleaning agents simply increase ECTFE
membrane flux and overall operating efficiency. ECTFE film vapour barrier properties make it particularly suitable for use in
pharmaceutical packaging applications.
PVdF
PVdF is a homopolymer of vinylidene fluoride having the formula [CH2-CF2]n PVdF polymers melt at 160° C, are melt processable,
and are supplied in the form of powder, pellets, and dispersions. Some grades of PVdF may contain other fluorinated monomers
eg a copolymer of vinylidene fluoride and hexafluoropropylene having the formula [CF(CF3)-(CF2)x(CH2-CF2 )y]n.
PVdF is a tough polymer and is resistant to UV attack. As a result of these properties major applications include architectural
coatings in building cladding and wire and cable jacketing.
THV
THV is a terpolymer of tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride with the formula [CF(CF3 )-CF2 )x(CF2-
CF2)V(CF2- CF2)z]n. THV is melt processable with melting points from 120° to 230° C depending on grade. It is available as
pellets, agglomerates or aqueous dispersions.
Fluorinated FluoropolymersETFE
ETFE is a tough, easily processable thermoplastic. As a film, it offers outstanding UV resistance combined with excellent light
transmittance, making it the material of choice for architectural roofing for large structures such as sports stadia. The film’s non-
stick/self cleaning properties also help reduce maintenance costs.
Another common application is in the wire and cable industry where ETFE’s combinations of toughness and dielectric properties
are employed.
How are Fluoropolymers manufactured?PTFE is used here as an example of fluoropolymer manufacture.
Polytetrafluoroethylene (PTFE) is a polymer made of long, linear polymer chains containing only carbon and fluorine atoms. This
gives the polymer its exceptional properties. It is produced from tetrafluoroethylene (TFE) which is the starting material (called a
monomer). TFE is made in several steps starting from common salt (sodium chloride NaCl), methane and from an ore called
fluorspar. TFE gas is introduced into a closed vessel under pressure and is polymerised using a catalyst to form very long chains.
Polymerisation reactions are often initiated with active molecules called "free radicals”. Radical initiated reactions can run very
fast and give out a great deal of heat. To prevent such reactions running out of control, the reaction vessels are water cooled;
even so, great care must be taken not to allow reaction conditions to become unstable. As well as temperature control, polymer
chemists can modify reaction conditions by the use of chemicals (chain transfer agents) and can modify the polymer itself by the
use of different comonomers to produce copolymers
Mineral Photos - Fluorite
Mii Photos
Florite Photo from Mii,Courtesy of Smithsonian Institute
Fluorite (fluorspar): Used in production of hydrofluoric acid, which is used in the electroplating, stainless steel, refrigerant, and plastics industries, in production of aluminum fluoride, which is used in aluminum smelting, as a flux in ceramics and glass, in steel furnaces, and in emery wheels, optics, and welding rods.
Background
When found in nature, fluorspar is known by the mineral name fluorite. Fluorspar (fluorite) is calcium fluoride (CaF2). It is found in a variety of geologic environments. Fluorspar is found in granite (igneous rock), it fills cracks and holes in sandstone, and it is
found in large deposits in limestone (sedimentary rock). The term fluorspar, when used as a commodity name, also refers to calcium fluoride formed as a by-product of industrial processes.
Fluorspar is relatively soft, number 4 on Mohs' scale of hardness. Pure fluorspar is colorless, but a variety of impurities give fluorite a rainbow of different colors, including green, purple, blue, yellow, pink, brown, and black. It has a pronounced cleavage, which means it breaks on flat planes. Fluorite crystals can be well formed, beautiful and highly prized by collectors.
Despite its beauty and physical properties, fluorspar is primarily valuable for its fluorine content.
Name
Even though fluorite contains the element fluorine, its name is not derived from its chemical composition. The name was given by Georg Agricola in 1546 and was derived from the Latin verb fluere which means to flow because it melts easily.
Spar is a generic name used by mineralogists to refer to any non-metallic mineral that breaks easily to produce flat surfaces and which has a glassy luster.
A miner’s name used long ago for fluorite was Blue John.
Sources
The United States once produced large quantities of mineral fluorspar. However, the great fluorspar mines of the Illinois-Kentucky fluorite district are now closed. Today, the United States imports fluorspar from China, South Africa, Mexico, and other countries.
A small percentage of the fluorspar consumed in the United States is derived as a by-product of industrial processes. For instance, an estimated 5,000 to 8,000 tons of synthetic fluorspar is produced each year in the uranium enrichment process, the refining of petroleum, and in treating stainless steel. Hydrofluoric acid (HF) and other fluorides are recovered during the production of aluminum.
Uses
The majority of the United States’ annual consumption of fluorspar is for the production of hydrofluoric acid (HF) and aluminum fluoride (AlF3). HF is a key ingredient for the production of all organic and non-organic chemicals that contain the element fluorine. It is also used in the manufacture of uranium. AlF3 is used in the production of aluminum.
The remainder of fluorspar consumption is as a flux in making steel, glass, enamel, and other products. A flux is a substance that lowers the melting temperature of a material.
Substitutes and Alternative Sources
Phosphoric acid plants, which process phosphate rock into phosphoric acid, produce a by-product chemical called fluorosilicic acid. This is used to fluoridate public water supplies or to produce AlF3. Phosphate-rich rocks are a minor alternative source for elemental fluorine.
Yellow fluorite from Illinois
Pink fluorite from Peru
Green fluorite from Colorado
History of FluoropolymersThe story of Fluoropolymers began on April 6, 1938, at DuPont's Jackson Laboratory in New Jersey. Dr. Roy J. Plunkett’s first
assignment at DuPont was researching new chlorofluorocarbon refrigerants. Plunkett had produced 100 pounds of
tetrafluoroethylene gas (TFE) and stored it in small cylinders at very low temperatures preparatory to chlorinating it. When he and
his helper prepared a cylinder for use, none of the gas came out—yet the cylinder weighed the same as before. They opened it
and found a white powder, which Plunkett had the presence of mind to characterise. He found the substance to be heat resistant
and chemically inert and to have very low surface friction.
PTFE is inert to virtually all chemicals and is considered the most slippery material in existence. These properties have made it
one of the most valuable and versatile materials ever invented, contributing to significant advancement in areas such as
aerospace, communications, electronics, industrial processes and architecture.
PTFE has become recognised worldwide for the superior non-stick properties associated with its use as a coating on cookware and
as a soil and stain repellent for fabrics and textile products.
Following the discovery of PTFE a large family of other fluoropolymers has been developed. The introduction of the combination of
fluorinated or non fluorinated monomers allowed the industry to design a large number of different polymers with a wide range of
processing and use temperatures.
What makes Fluoropolymers so versatile?All fluoropolymers are normally regarded as completely insoluble. Only perfluorocarbons, perfluorocarbon ethers, perhalocarbons,
sulphur hexafluoride and carbon dioxide are known to dissolve fluoropolymers and only under the right conditions of temperature
and pressure.
For example PTFE is completely insoluble in most common solvents and will not contaminate ultra-pure or corrosive applications.
Prime quality PTFE resins are very pure and this level of purity can be translated to the final product using a range of moulding
methods. The finished products manufactured from PTFE have very high purity coupled with low porosity and low levels of
extractables.
Fluoropolymers resist chemical attack from virtually all acids, bases, and solvents. A complete chemical resistance chart is
available. Because of the size of fluorine molecules, Fluoropolymers also have low chemical permeability.
The substitution of fluorine for hydrogen contributes to the numerous performance properties of fluoropolymers, such as:
High Flexibility
PTFE has good flexural properties even in the cryogenic range and outstanding resistance to fatigue. Flexural properties are
strongly dependent on degree of crystallinity and great care is necessary in the selection of polymer grade and in processing
conditions to achieve maximum flex life.
High thermal stability
Fluoropolymers have a working temperature range of minus 240°C to + 300° C, and their chemical and electrical properties
remain stable for much of that range.
Non-flammability and high melting-point
Fluoropolymers have the lowest heat of combustion of all known polymers. Additionally, Fluoropolymers have the lowest rate of
flame spreading. Fluoropolymers are therefore very difficult to ignite and will stop burning ("self-extinguish”) once the supporting
flame is removed. Even though some references show an ignition temperature of 530° to 580° C, many consider FPs as plastics
that do not burn.
Low coefficient of friction, surface energy and porosity
Fluoropolymers have the lowest coefficient of friction of any polymer. Static and dynamic coefficients of friction are equal so there
is no stick-slip movement. In particular PTFE has a low surface energy and is very difficult to "wet”. PTFE has exceptionally low
porosity and hence anti-adhesion properties . Other materials exhibit little or no adhesion to PTFE.
Electrical Properties
Fluoropolymers have exceptional electrical properties with an extremely high electrical resistance and with a low dielectric
constant and dielectric loss factor. Fluoropolymers also have good arc and tracking resistance, and high surface resistance.
Typical propertiesApplications for fluoropolymers are driven by their superior physical and chemical properties.
Chemical Inertness
Fluoropolymers are used in harsh environments where their chemical resistance has made them very useful in the many
industrial processes such as linings for vessels and piping, fly ash collector bags, gasket packing, semiconductor equipment,
carrier materials, chemical tanks and as packing for lithium-ion batteries.
High Dielectric
The dielectric properties of these unique polymers have made possible the miniaturisation of circuit boards. This concept is
responsible for the very latest in high-speed, high-frequency radar and communications found in the newest defence systems as
well as in the next generation of ultra high speed computers.
Flame Retardancy
Fluoropolymers meet exacting industry standards in relation to electrical properties and flame retardancy. Examples of these
applications are wire coating (robots, personal computers, communication industry, response to high frequencies, electrical
systems in aircraft, etc.) fibre optics, cable coating and electrical and electronic components.
Low Friction
Fluoropolymers exhibit very low coefficients of friction. For example PTFE is uniquely used as bearing pads for bridges. Where this
characteristic is used in abrasive environments inert fillers are often added to improve their abrasion resistance. For example high
performance automotive and aircraft bearings and seals are now commonly made from fluoropolymers.
Non Stick
Fluoropolymers are used in everyday life as their unique characteristics offer advantages. They are used in household
kitchenware coatings (pans, rice cookers, knives etc.), fixed rolls for printers, parts for transferring paper in photocopiers.
Weatherability
The performance of fluoropolymers does not deteriorate significantly in an outdoor environment. They are suitable for use over
long periods of time without maintenance. They are used in architectural applications, as films for greenhouse applications,
photovoltaic cell film cover and UV resistant paints.
Inertness and Barrier Properties
The bio-medical field uses fluoropolymers in devices such as catheters and other parts with which to perform diagnostic and
therapeutic procedures. Fluoropolymers’ superior barrier properties are exploited in pharmaceutical packaging where their high
resistance to moisture protects pharmaceutical products. Fluoropolymers have a high resistance to gasoline and this property is
exploited in parts manufactured for the automotive industry.
European Food Contact ApplicationsThe European Food Safety Authority (EFSA), has approved for food contact applications:- "the use [of the perfluorinated chemicals
in the production of polytetrafluoroethylene (PTFE)] for repeated use articles, sintered at high temperature” and indicated that
"consumer exposure from use of perfluorooctanoic acid, ammonium salt in repeated use articles, is considered negligible”.-
August 2005.
There are other fluoropolymer types that are approved for food contact applications and more details of these can be obtained
directly from your supplier
Recovery and Disposal of Fluoropolymer WasteRecovery
Fluoropolymers are usually employed in small components in specific complex applications such as electronic equipment,
transport (cars, trains and airplanes) or as very thin layer coatings on fabrics and metals. Where sufficient quantities of
fluoropolymers can be recovered and may be sufficient to warrant recycling then they should be shipped to specialist recyclers.
A very substantial market exists for recovered fluoropolymers as low friction additives to other materials. For example PTFE is
typically ground into fine powders and used in such products as inks and paints.
Disposal
Fluoropolymer waste should be incinerated in authorised incinerators. Preferably, non-recyclable fluoropolymers should be sent to
incinerators with energy recovery. Disposal in authorised landfills is also acceptable.
PETIf you ever had fizzy drink, water or fruit juice from a plastic bottle then more than likely the bottle is made of PET, or
polyethylene terephthalate. PET is one of the most commonly used plastics in Europe’s packaging industry for several reasons. It
is very strong, it can withstand high pressures and being dropped without bursting. It has excellent gas barrier properties, so it
keeps the fizz in fizzy drinks, and protects the taste of the drinks in the bottles.
PET is a short name for a unique plastic belonging to the family of polyesters, the word is made up from 'poly-' , the Greek word
for many and '-esters' which are compounds formed by reaction of alcohols with acids via a chemical bonding known as an ester
linkage. PET polyester is formed from the alcohol - ethylene glycol [EG] - and the acid - terephthalic acid [TPA],] - and its chemical
name is - Polyethylene terephthalate or PET.
The raw materials for PET are derived from crude oil. After refining and separating the 'crude' into a variety of petroleum
products, the two PET feedstocks or monomers are eventually obtained, purified, and mixed together in a large sealed, 'cooking
pot' type of vessel and heated up to 300°C in the presence of a catalyst. Each intermediate has two identical points for reaction
and is therefore capable of forming chains by linking several single molecules together and forming a polymer where the
monomers are bonded by ester linkages.
Benefits of PET
Because PET is easily processed by or injection and blow moulding as well as extrusion when in the molten state, it can be
tailored to almost any packaging requirement. Typical applications of PET include:
Bottles for beverages such as soft drinks, fruit juices, mineral waters. It is especially suitable for carbonated drinks,
cooking and salad oils, sauces and dressings and detergents.
Wide mouth jars and tubs for jams, preserves, fruits & dried foods.
Trays for pre-cooked meals that can be re-heated in either microwave or conventional ovens. Pasta dishes, meats and
vegetables.
Foils for 'boil-in-the-bag' pre-cooked meals, snack foods, nuts, sweets, long life confectionery.
Other PET products with an extra oxygen barrier are ideal for containing beer, vacuum packed dairy products e.g.,
cheese, processed meats, 'Bag in Box' wines, condiments, coffee, cakes, syrups.

What is PET?PET is a short name for a unique plastic belonging to the family of polyesters, the word is made up from 'poly-' , the Greek word
for many and '-esters' which are compounds formed by reaction of alcohols with acids via a chemical bonding known as an ester
linkage . There are literally thousands of known esters which appear in many different forms, most flavours and essences are
esters, fats are esters of 'fatty acids' and glycerol, the ester - acetyl salicylate - is better known as 'Aspirin'. PET polyester is
formed from the alcohol - ethylene glycol [EG] - and the acid - terephthalic acid [TPA], or its derivative dimethyleterephthalate
[DMT] - and its chemical name is - Polyethylene terephthalate or PET.
How is PET manufactured?
The raw materials for PET are derived from crude oil, as are many other plastics - after refining and
separating the 'crude' into a variety of petroleum products the two PET intermediates or monomers are
eventually obtained, purified, and mixed together in a large sealed, 'cooking pot' type of vessel and
heated up to 280 to 300 ¼C under a slowly reducing the pressure. Each intermediate has two identical
points for reaction and is therefore capable of forming chains by linking several single molecules
together and forming a polymer where the monomers are bonded by ester linkages.
The mixture becomes more and more viscous as the reaction proceeds and it is eventually halted once
the appropriate viscosity is reached. At this stage the PET is extruded from the reactor in the form of thin 'spaghetti like' strands,
cooled quickly under water and chopped into small transparent granules or pellets before drying and transfer to other treatment
stages. PET for manufacture of cola bottles is further refined by heating the solid granules below their melting point which distills
out some impurities and at the same time enhances the physical properties of the material.
What is the origin of PET?PET was originally synthesized by Dupont chemists during a search for polymers to make new textile fibres, but the
technology for making the very the long chains was developed by ICI (Imperial Chemical Industries) in 1941.
Polyester fibre applications have developed to such an extent that by the late 1990's PET represented over 50% of
world synthetic fibre manufacture. It is used alone or to blend with cotton or wool to confer better wash/wear and
crease resistant properties, in fibre form it is better known as 'Dacron' or 'Trevira'. In the late 1950's, PET was
developed as a film by stretching a thin extruded sheet in two directions; in this form PET film finds extensive use as
video, photographic and X-ray film in addition to uses in packaging.
In the early 1970's, stretching in three dimensions by blow moulding - similar to inflating a balloon in a shaped mould
- produced the first bottle type containers initiating the exploitation of PET as a lightweight, tough, unbreakable substitute for the
glass bottle
What makes PET so versatile?
Careful manipulation of PET generates the wide range of useful products we see as variants of the same chemical formula.
PET is easily processed by extrusion or injection moulding when in the molten state, obtaining an amorphous article of practically
any shape. Its properties can then be tailored to the needs, simply heating the article above its glass transition temperature [ca
72°C]. In this state the polymer chains are capable of being stretched in one direction [fibres] or in two directions [films and
bottles]; if cooled quickly while stretched, the chains are frozen with their orientation intact. Once set in this stretched form the
material is extremely tough and confers the properties we see in a typical polyester bottle, photographic film or fibre. If PET is
held in the stretched form for a period at temperatures above the glass transition, it slowly crystallizes and the material starts to
become opaque, more rigid and less flexible [crystalline PET or CPET]. However, in this crystalline form it is used for trays and
containers capable of withstanding moderate oven temperatures.
PET as a packaging materialThe basic chemical structure of PET is essentially inert and resists attack by many
potent chemicals. The molecular chains are packed together extremely tightly forming
a very tough, dense, but a sparkling transparent material which resists gas
penetration [carbon dioxide and oxygen] better that most other common polymers. It
is also very resistant to biochemical attack and environmentally benign, a unique
combination of properties which make it an excellent material for packaging of foods.
PET is easy to process by simple heating and stretching treatments forming trays,
sheets, foils, tubs, and glass clear bottles that do not break

Comments of the PET Committee on blending of recycled and virgin PET
The use of blends of virgin and recycled PET (Polyethylene-terephthalate) for the manufacture of food contact packaging is
becoming more and more common. Several customers purchase virgin PET from PET producers which are members of
PlasticsEurope and blend it with recycled polymer, where the percentage of recycled PET in the blend is often up to 50%, and
sometimes even higher.
PlasticsEurope places the health and safety of consumers as its highest priority. PET recycled for food contact applications is fully
acknowledged by PlasticsEurope, if approved by specific national legislation and complying with the product safety requirements
of EC Directive 2002/72/EC for plastics materials and articles that are intended to come into contact with foodstuffs.
Virgin PET's well-known safety is proven by decades of safe use and is beyond argument. To achieve the same high standards for
recycled PET the quality control of recycled PET should be comparable to those used by manufacturers of virgin PET.
It is expected that the proposed Regulation for the Recycle of Plastics back to Food Contact will lay down requirements for high
standards of quality control that will ensure consumer health and safety.
Against the backdrop of the PlasticEurope´s PET producers dedication to consumer health and safety, it is important for the PET
producers represented within PlasticsEurope to point out, that they can take responsibility for the recycled part of such blends
with respect to their compliance with EC Directive 2002/72/EC only if supplied by themselves.
Health and safety - Food contact legislationUpdated July 2004
This note is a brief summary of the regulatory status of PET food packaging materials and outlines the principles involved. For
more comprehensive details concerning these regulations the reader should consult the particular regulations in question, contact
the appropriate regulatory body or seek additional information from PlasticsEurope (formerly APME) PET producers.
The relevant European Union legislation is still in the process of harmonisation across the Member States but the basic principles
of food contact regulation are now well established in the EC "Framework Directive" [89/109/EEC]. The Directive states that:
"Materials and articles must be manufactured in accordance with Good Manufacturing Practice [GMP] so that, under normal
conditions of use, they do not transfer any of their constituents to foodstuffs in quantities that could endanger human health,
bring about an unacceptable change in the composition of the foodstuffs or cause a deterioration in the organoleptic [taste/odour]
characteristics".
The Directive also requires that food contact materials and articles should be 'positively labelled' to the effect that they are
suitable for the declared conditions of use. Any changes or amendments to this law are decided by the Codecision Procedure EU
Council of Ministers following the advice of European Food Safety Authority (EFSA) an appointed body of European experts. The
Directive defines the requirements for all materials intended for all food contact applications, not only plastics.
Within this Framework Directive there is a specific Directive for all plastics [2002/72/EC] including PET. In general, Directive
2002/72/EC requires the establishment of, 'Positive lists' of authorised substances, which may be used in manufacture of plastics
and plastic articles.
An "overall migration limit" (OML), defined as the limit on any substance, which might possibly transfer into the food.
Where necessary, specific migration limits (SML's) or compositional limits (QM's or QMA's) for particular substances.
These two Directives, and related amendments (e.g. 2nd amendment of Directive 2002/72/EC published 2004) are intended to
give consumers maximal protection. Detailed tests that have to be applied to ensure compliance with the legislation are covered
in several other directives including (see practical guide). The Framework Directive is being revised and the amended version is
expected within 2004. Concurrently, the Plastics Directive and the Migration Directives with amendments are being consolidated
in one "Super Directive".
Other countries (e.g. USA, Japan) have similar regulatory requirements to those of the EU. The procedures and responsibilities are
also similar, i.e., the producers and users of materials and articles must ensure compliance under the conditions of intended use.
PET materials supplied for use in food packaging applications have been subjected to careful review by all the appropriate
regulatory bodies around the world and may be used with complete safety in contact with food and beverages.
PET producers, converters and packers/fillers constantly monitor developments in the regulatory processes to ensure that all their
products and articles are in compliance. Producers and their trade association [PlasticsEurope], provide more specific details and
advice on compliance requirements.
Typical applications of PETBottles
Beverages, Cola and soft drinks, fruit juices, mineral waters. Especially suitable for carbonated drinks. Cooking and salad oils,
sauces and dressings. Detergents.
Wide mouth jars and tubs
Jams, preserves, fruits & dried foods.
Trays
Pre-cooked meals for re-heating in either microwave or conventional ovens. Pasta dishes, meats and vegetables.
Foils
'Boil in bag' pre-cooked meals, snack foods, nuts, sweets, long life confectionery.
PET Products with extra oxygen barrier
Beer, vacuum packed dairy products e.g., cheese, processed meats, 'Bag in Box' wines, condiments, coffee, cakes, syrups.
PET bottlesThe PET bottle is the modern, hygienic package of choice for many food products, particularly beverages and
mineral waters. The main reasons for its popularity are its glass like transparency, ability to retain carbonation and
freshness, a toughness per weight ratio which allows manufacture of lightweight, large capacity, safe unbreakable
containers. The proportion of package weight compared to the contents allows very favourable distribution
economics which reduces overall system costs. For example, a typical transporter vehicle would transport 93% of
beverage and 7% of PET bottle material compared with a glass bottle transporting 57% beverage and 43%
unwanted glass. This ratio is particularly advantageous when measuring fuel consumption
per litre of beverage delivered.
PET bottles and jars are manufactured by the process of injection stretch blow moulding. A
preform, parison or pre-moulding is first formed by injecting molten PET into a cooled
mould. The preform is then carefully heated in a second process stage before using air
pressure, assisted by a rod, to quickly stretch and form the PET material by blowing into a larger mould in
the shape of the desired container followed by cooling. If the desired container is a bottle or jar the screw
thread is formed during the preform manufacturing stage.
Selection of the processing temperatures is vital to achieve the best balance of properties. Toughness,
transparency, stiffness, gas resistance properties are all maximised during this part of the process. Tubs
can also be made by this process but thermoforming is the preferred option.
The weight of a typical 1.5 litre single trip cola bottle would be about 40 to 45g. about one tenth the
weight of an equivalent glass bottle
Reusable / refillable PET bottlesTraditionally the glass bottle has been the material of choice in this end use because practical alternatives have not been
available. PET now provides an alternative to glass, PET offers similar size with 75 % less material weight, it is unbreakable and
allows the use of larger size containers for carbonated products with a higher degree of safety. However, PET is absorbent to
some degree and therefore requires a more strict approach to segregation of unsuitable bottles. Rigorous cleaning and
sterilisation procedures must be followed to guarantee product safety and consumer acceptance.
Many very detailed studies have now been completed investigating all the health, safety and
environmental aspects of using PET in refillable bottle systems.
The weight of a typical refillable PET bottle would be around twice the weight of a single trip PET bottle
at about 80g., approximately one fifth of an equivalent glass bottle.
Refillable PET bottles are now used extensively in Scandinavia and countries like Germany, The
Netherlands and Switzerland.
PET trays and blister packsSemi rigid PET sheet, the precursor for thermoforming PET articles, is made by a extruding a
ribbon of molten PET polymer on to a series of cooling and compressing rolls, usually in a
'stack' of three. The cooled sheet is then stored before feeding through a thermoforming line
which heats the sheet, stamp forms, and cuts out the article all in one process. Similar
principles to those in stretch blow moulding apply but the operation is less critical and the
range of properties less demanding
PET films and foils
Manufacture of very thin highly stretched PET film is a much more demanding operation which develops fully the properties of the
PET. Film packaging applications approximate to around 20% of PET film use, it finds a wide range of applications in magnetic
tapes, photographic films, photoresist and hot stamping foils in addition to packaging outlets.
The excellent thermal properties of PET allow processing and use over a wider temperature
range (-70 to +150 ¼C) than most common packaging films. It is ideal for retort packaging,
dual ovenable lidding and 'boil in the bag' applications. PET film has the chemical inertness
and good gas barrier properties that are important for many medical, pharmaceutical and
food products, they can be used in the demanding steam, ethylene oxide and radiation
sterilisation processes.
The key to achieving these highly prized film properties is in the way the material is
manipulated during the hot stretching and heat annealing section of the process, which is
called 'stentering'
Eco-profiles PET & LCA studiesEnvironmental auditing of processes is usually carried out by applying the technique of Life Cycle Assessment (LCA). A Life Cycle
Inventory (LCI) first catalogues all the raw materials, energy consumption and wastes generated during the whole product cycle,
i.e. the so-called 'Cradle to Grave' inventory.
To facilitate the inventory phase for polymers, PlasticsEurope has prepared eco-profiles for the most important plastics. Eco-
profiles are block collections of average ‘Cradle to Gate’ industry data; i.e., they start with raw materials in the earth and end with
polymers ready for despatch to converters. Among others, eco-profiles of PET resin and PET film have been published by
PlasticsEurope in its series of polymer eco-profiles. An eco-profile for the manufacture of PET bottles is also available. All these
reports can be read on, or downloaded from, this, the PlasticsEurope website.
Every LCA carried out so far on PET containers has shown sound environmental performance.
This has recently been confirmed by an LCA carried out in 2004 by IFEU GmbH (Heidelberg) on behalf of PETCORE (Brussels). This
study compared single use PET bottles for mineral water, carbonated and non-carbonated soft drinks with refillable glass bottles
for the same beverages, with focus on the German market. It was conducted in accordance with International Standards (ISO
14040) and peer reviewed.
Although several studies with similar goals have been done in the past, this was the first study in which the system boundaries
were expanded to include the additional products obtained from the recycle of post use PET bottles. In this way, it was possible to
avoid partitioning the benefits of recycling between the system of PET bottles and that of articles from recycled PET. As there is
no scientific way of partitioning benefits among several product flows, the interpretation of LCA’s involving additional products is
often uncertain unless the boundaries are enlarged.
The conclusions of the IFEU study were:
Under the conditions of kerbside collection of PET single use bottles (DSD system), there is no clear environmental
advantage for either of the two packaging systems.
Instead, under the conditions of a deposit based collection system and shipping of significant amounts of baled bottles to
the Far East for recycling, there is a clear environmental advantage for refillable glass bottles. However, this advantage
would disappear if recycling of PET bottles were carried out in Europe.
Recovery & recycling of PETThe EU Packaging and Packaging Waste Directive
The European Union, with the adoption of its Packaging and Packaging Waste Directive, 94/62/EC as amended by 2004/12/EC, is
legislating for more effective recovery of used packaging and for the reduction of the impact of packaging on the environment.
a) More effective recovery
Recovery of PET packaging falls under the requirements for recovery and is classed together with other plastic materials in the
targets laid down in directive 2004/12/EC:
Overall recovery: minimum 60% of packaging waste Overall recycling of packaging waste (including feedstock recycling):
between 55% and 80% Minimum recycling differentiated by material, for plastics 22.5% (including only what is recycled back to
plastics)
Member States must meet these targets by 2008, with the exception of Greece, Ireland, Portugal, and the accession countries,
which are allowed to delay their attainment.
b) Minimisation of the environmental impact
To be allowed on the market, packaging articles must comply with the following essential requirements:
The content of heavy metals (Cd, CrVI, Hg, and Pb) must be lower than 100 ppm.
The use of substances dangerous for the environment must be minimised.
The articles must be recoverable by material recycling, organic recycling, and/or energy recovery (at least one of the
three).
They must be suitable for reuse (when relevant and claimed).
The volume or weight of the packaging article must be limited to the minimum adequate amount to maintain the
necessary level of safety, hygiene, and consumer acceptance.
c) Status of PET
PET is widely recycled as a material, making a large contribution to the recycling targets required for plastics by the EU directive.
When material recycling is not feasible, PET can be incinerated with energy recovery.
Moreover, PET usually does not contain heavy metals and/or substances dangerous for the environment.
The introduction of the PET bottle has created a number of dilemmas, which are currently being resolved slowly by a mixture of
political and commercial considerations. The commercial advantages are well understood. However, the traditional use of
refillable glass in many northern European countries has resisted the widespread use of the single use PET container that is more
prevalent in southern Europe. A refillable PET bottle has been developed and is now used widely in the Nordic countries,
Germany, The Netherlands, and Switzerland.
The pursuit of commercial freedom within Europe is a central stone of the EU trade policy, but concerns around unsatisfactory
disposal schemes for single use PET containers need to be resolved to the satisfaction of the relevant authorities before complete
harmonisation of distribution systems is achieved. In Germany, Denmark, Finland, Norway, The Netherlands and Sweden all
beverage containers, single use and refillable, are distributed and collected via a mandatory deposit refund system. Switzerland
manages an advanced disposal fee to fund a voluntary collection scheme. The majority of the other European countries are
including the collection of PET containers in more comprehensive schemes for separate collection of packaging waste set up to
comply with the EU directive.
Recycling of PET containers
PET container recycling is a healthy industry and growing very steadily. Even if the PET consumption rate will follow predictions at
around 2.5 to 3.0 million tonnes beyond the year 2007, meeting the EU recycling targets should not be a challenge to the current
growth in recycling of approximately 10% pa. Regular information on recovery and recycling of PET can be obtained from
PETCORE (www.petcore.org), a European organisation constituted solely to facilitate the recycling of PET containers. Similar
organisations are operating on other continents as NAPCOR (www.napcor.com) in the US and the Council for PET Bottle Recycling
(www.petbottle-rec.gr.jp/english/en_top.html) in Japan; all offer guidance on recovery procedures.
To assist the overall process of recycling there are guides to good container design and a common specification for collected used
PET containers. Sophisticated container sorting equipment, using X-rays and optical sensors, is automated to a level that ensures
almost 100% separation of PET from other container types.
There are now clear programmes in place to meet the EU recovery targets and establish recycling of PET as a sustainable
process.
PET recovery processes and sustainability
PET can be recovered, and the material reused, by simple washing processes to regenerate clean washed polymer flake
(mechanical recycling), or by chemical treatment to break down the PET into oligomers or up to the starting monomers,
terephthalic acid and ethylene glycol (chemical recycling). These intermediates are then purified and repolymerised into new PET
resins. A final option, for PET that is unsuitable for material recycling (e.g., very dirty, or too contaminated to clean), is to use PET
as an energy source.
Purity is essential for good quality mechanical recycling. Discrete physical contamination is usually easy to remove i.e., dirt, glass
fragments, stones, grit, soil, paper, glues, product residues and other plastics like PVC and PE. However, ingrained soil caused by
abrasion or grinding, for example during baling, transport or handling in poor storage conditions, is difficult to dislodge and will
need some filtration to ensure removal. Oils, fats, and greases need more detergents and contaminate wash waters excessively,
although leaving no residual quality problems. Chemical contamination occurs by adsorption of contents as flavourings, essential
oils, or similar ingredients used in the product formulations. Contamination can also be introduced by consumer misuse of the
container for purposes other than the original intention e.g., storage of pesticides, household chemicals, or motor and fuel oils.
Complete removal will require desorption, a slow process, hence with reduced productivity. However, these occurrences are few,
and are not known to cause many problems during reprocessing. For some low risk applications, like non-food contact and fibres,
incidental product contamination is likely to be insignificant. For other uses, appearance and odour are important. The intended
use of the recycled PET often determines the feedstock purity requirements.
Chemical recycling processes are generally less sensitive to purity of feedstock than mechanical ones, as they include efficient
purification steps.
Recovery of PET by combustion in waste-to-energy power generation plants is a useful method of utilising the high intrinsic
energy content of PET (23 MJ/kg, comparable to that of soft coal). If this type of plant is not available, simple incineration is then
the alternative option. Combustion of PET is perfectly safe; containing only carbon, hydrogen, and oxygen, with controlled burning
its combustion generates only carbon dioxide and water. The volume of ash generated is parts per million, essentially insoluble
and can be treated in the same manner as other resulting ashes.
In landfills, PET is stable and inert with no leaching or groundwater risk. Bottles are crushed to very small volume, take up
relatively little space, and generally add a degree of stability to the landfill.

Uses of recycled PET (R-PET)
Clean, recovered R-PET flake is virtually indistinguishable from virgin PET and can be converted into many different products
competing in the same markets. It is used again in bottles for non-food end uses like household chemicals and cleaners. In
countries where local laws allow it, the use of R PET for the manufacture of new beverage bottles is growing rapidly.
However, the major secondary use is for the manufacture of polyester fibres then used to make clothing, either directly or as a
filling fibre in anoraks and bedding. The fibres are also used extensively for carpets and scouring and cleaning pads. Protective
packaging for delicate articles, like eggs, and plants for despatch through the mail, are manufactured from R-PET using
thermoforming techniques.

Recycled PET for food contact applicationsIn the context of food contact, PlasticsEurope considers that protection of health and safety of consumers - as well as compliance
with applicable regulations - must have priority over all other considerations.
Technological advances over the last decade have led to the development of manufacturing processes that now make it possible
to supply recycled PET for food contact use that meet the same standards in hygiene and safety as virgin PET.
Although several member states, e.g., Germany, The Netherlands, have recognized these advances and have established
regulations that assure that recycled PET is safe for use in food packaging, there is currently no regulatory consistency among
these member states and other states have not yet established suitable regulations. To establish a consistent, harmonized
system that assures the safety of recycled PET and to regulate recycle processes, the European Commission has prepared a draft
regulation on "Recycled Plastics Materials and Articles Intended for Food Contact".
PlasticsEurope PET Group wholeheartedly supports this draft regulation and believes it will protect the health and safety of
consumers and facilitate the environmentally sound use of recycled PET in food packaging.
Polycarbonate The term Polycarbonate describes a polymer which is composed of many ("poly") identical units of bisphenol A connected by
carbonate-linkages in its backbone chain. Chemically, a carbonate group is a di-ester of carbonic acid, the result of which is a
polymeric chain. Polycarbonate is transformed into the required shape by melting it and forcing it under pressure into a mould or
die. There are two dominant processes involved in making products from polycarbonate:
Extrusion : The polymer melt is continuously pressed through an orifice called a "die", which gives the molten polymer
its final shape.This process makes it possible to create infinitely long pipes, profiles or sheets.
Injection moulding : The hot polymer melt is pressed into a mould. The mould is then cooled, and the hot polymer
solidifies taking on all the characteristics of the mould. This process is used to make single-end products, such as
housings, plates, bottles and many other applications.
Benefits of Polycarbonate
Polycarbonate offers many outstanding characteristics, including:
High transparency, making it ideal for use in protective panelling
High strength, making it resistant to impact and fracture
High heat resistance, making it ideal for applications that require sterilisation
Good dimensional stability which permits it to retain its shape in a range of conditions
Good electrical insulation properties
Biologically inert
Readily recyclable
Easy to process
These characteristics make polycarbonate suitable for many applications, including:
Automotive: Polycarbonate plastic moulded mirror housings, tail lights, turn signals, back-up lights, fog lights, and
headlamps all contribute to a vehicle’s unique style.
Packaging: Polycarbonate bottles, containers and tableware can withstand extreme stress during use and cleaning,
including sterilisation. They can be used to serve, freeze and reheat food in the microwave making them time and energy
savers. Shatterproof and virtually unbreakable, polycarbonate is a safer alternative to glass.
Appliances & Consumer Goods: Polycarbonate’s moulding flexibility styling and colouring possibilities make it perfect
for use in electric kettles, fridges, food mixers, electrical shavers and hairdryers, while fulfilling all safety requirements
such as heat resistance and electrical insulation.
Electrical & Electronics: Polycarbonate’s light weight and impact- and shatter-resistant qualities make it perfect for
housing cell phones, computers, fax machines, and pagers while at the same time withstanding the bangs, scratches and
accidental drops of everyday use.

What is Polycarbonate?Polycarbonate plastic is a lightweight, high-performance plastic found in commonly used items such as
automobiles, cell phones, computers and other business equipment, sporting goods, consumer electronics,
household appliances, CDs, DVDs, food storage containers and bottles. The tough, durable, shatter- and heat-
resistant material is ideal for a myriad of applications and is found in thousands of every day products.
Polycarbonate's versatility makes it excellent for creating functional, as well as aesthetically pleasing
products. It can be easily moulded and dyed in hundreds of colours - for products from car mirror housings to
mobile phone coverings to microwaveable containers, and can also be perfectly transparent, making it ideal
for use in eyeglasses.
How are products made from PC?
Polycarbonate is transformed from prills or pellets into the desired shape for its intended application by melting
the polycarbonate and forcing it under pressure into a mould or die to give it the desired shape depending on the
application. This process is repeated thousands and thousands of times for a given part, such as a cell phone
housing. The part is generally then shipped to a manufacturer who assembles the final product.
There are two dominant processes involved in making products from polycarbonate:
Extrusion:
The polymer melt is continuously pressed through an orifice called a "die", which gives the molten polymer its final shape.
After passing through the die the melt cools rapidly and solidifies hence maintaining the given shape. This process makes
it possible to create infinitely long pipes, profiles or sheets.
Injection moulding:
The hot polymer melt is pressed into a mould. The mould is then cooled, and the hot polymer solidifies taking on all the
characteristics of the mould. This process is used to make single end products, such as housings, plates, bottles and
many other applications
Superior processability combined with excellent mechanical and physical properties makes polycarbonate
an outstanding engineering plastic, and the material of choice for many high quality, durable applications.
This combination of characteristics also allows designers broad design freedom.
PC chemistry & characteristicsWhat is the chemical structure of polycarbonate?
The term Polycarbonate describes a polymer which is composed of many ("poly") identical units of bisphenol A connected by
carbonate-linkages in its backbone chain. Chemically, a carbonate group is a di-ester of carbonic acid. The result is a polymeric
chain as can be seen in the scheme below:
How is polycarbonate made?
Polycarbonate is created by linking its main building unit, bisphenol A, via the formation of carbonate groups.
What are the beneficial characteristics of polycarbonate?
Polycarbonate is a thermoplastic characterised by a wide range of outstanding properties:
High transparency
High strength making it resistant to impact and fracture
High heat resistance, making it ideal for applications that require sterilisation
Good dimensional stability which permits it to retain its shape in a range of conditions
Good electrical insulation properties
Biologically inert
Readily recyclable
Excellent processability
Cost effective
This combination of properties has led to many beneficial, durable and unique applications in the electronic sector, in domestic
appliances and office equipment, in optical data storage media, in the construction industry, in automotive engineering, in food
and beverage containers, in medical devices and in leisure and safety equipment.
The history of PolycarbonateIn 1953, polycarbonate was discovered by Dr. H. Schnell at Bayer AG, Germany, and by D. W. Fox at General Electric Company,
USA working independently. In the late 1950´s polycarbonate began to be used in commercial applications.
Polycarbonate was initially used for electrical and electronic applications such as distributor and fuse boxes, displays and plug
connections and subsequently for glazing for greenhouses and public buildings. Soon polycarbonate’s outstanding combination of
beneficial characteristics made it the material of choice for many other applications.
In 1982, the first audio-CD was introduced to the market, quickly replacing audio records. Within 10 years optical media
technology included CD-ROMs, and within 15 years DVDs. All these optical data storage systems depend on polycarbonate.
Since the mid 1980´s, 18 litre water bottles made of polycarbonate have increasingly replaced heavy and fragile glass bottles.
These light-weight and shatter resistant bottles can now be found in many public buildings and offices.
Already used in the USA since the end of the 1980´s, automotive headlamps made of polycarbonate became authorised in Europe
in 1992. Today, only 10 years later, almost every new European car is equipped with polycarbonate headlamps.
The market of PolycarbonateIs polycarbonate a widely used plastic?
Yes. Polycarbonate is a high quality, engineering plastic with a unique combination of properties including strength, lightness,
durability, high transparency, heat resistance and is easily processed. Hence, it is found in a number of products from essential
medical devices, electronics equipment, computer housings, cars, building and construction applications as well as consumer
goods. It is also extensively used in optical data storage applications (e.g. CDs, DVDs), safety equipment and lightweight,
transparent roofing in building & construction.
In addition, as polycarbonate is highly durable and lightweight, it is the best choice for applications such as automotive
instrument panels, sculpted headlights and interior trim which all contribute to a reduced fuel consumption.
How large is the European market for polycarbonate?
The European demand for polycarbonate reached 400,000 tonnes in 1999. This represents around one third of the global
demand. The polycarbonate market is growing as new applications are developed and demand in existing sectors expands at a
significant rate. The demand for polycarbonate to manufacture optical media like CDs or DVDs is, for example, growing at around
30% per year. Overall, the European market is expanding at around 10% per annum.
The European polycarbonate market is valued at around 1.6 billion. The pie chart demonstrates the main market applications for
Europe; all of these applications are durable and long lasting.

What role does polycarbonate play in the European economy?
The polycarbonate industry itself employs approximately 7,000 people. Additionally, it is estimated that in 1999 around 160,000
jobs directly depended on polycarbonate and its end products and applications. In terms of market value, these polycarbonate
products and applications correspond to a European output of approximately 12 billion euros. Polycarbonate is essential in the
field of Information and Communications Technology in Europe, which employs in excess of 5 million people.

How large is the global market for polycarbonate?
The global market for polycarbonate has grown from 600,000 tonnes in 1990 to 1,800,000 tonnes (see chart) in 2000. Market
growth is expected to continue with an average growth rate of approximately 10% as new developments and applications
contribute to the quality of life for consumers.

PC health and safetyHow does PC contribute to human health and safety?
Polycarbonate positively contributes to consumers' comfort and safety through its use in a vast array of applications. For
example, due to polycarbonate's strength and impact resistance, it is used in safety lenses to protect the eyes of workers and
sportspeople, as well as anyone enjoying an active lifestyle. In addition, unbreakable and shatterproof food containers and bottles
made from polycarbonate avoid the risk of cuts from broken glass while keeping food fresh and safe to eat. Polycarbonate used in
medical devices supports medical treatments, which in turn prolong life expectancy.
Can I be confident PC products are safe to use?
Yes. More than four decades of research and extensive use throughout the world demonstrate that polycarbonate and BPA, from
which it is made, are safe for all intended uses.
Is PC as a plastic safe for use in contact with food?
Yes. Over four decades of research and extensive use throughout the world demonstrate that polycarbonate plastic can safely be
used in contact with food. It meets all relevant government food contact requirements.
Does polycarbonate plastic meet EU food contact regulations?
Yes. The European Commission’s expert body, the Scientific Committee on Food (SCF), recently reconfirmed that polycarbonate
food contact applications are safe for intended uses and meet EU requirements. These applications also meet the requirements of
the U.S. Food and Drug Administration (FDA), the Japanese Ministry of Health and Welfare and other international regulatory
bodies.

Does PC have an affect on the environment?
Emissions to the environment from the production of polycarbonate are extremely low. It is produced in closed processes
(meaning the material is piped from one closed vessel to another) with careful emission treatment practices.
Long life expectancy products, which are expected to last and be used for years, are typical for polycarbonate. Many applications
even help to save resources, such as light weight polycarbonate containers that reduce fuel consumption during transport,
lightweight and aerodynamic automotive parts that reduce fuel consumption, and multi-wall sheets which are heat insulating and
contribute to energy savings.
At the end of a polycarbonate product´s life it can be recovered, recycled and disposed of safely.
Applications overview
AutomotiveToday’s sleek automobiles combine style with high performance and durability on the road; vehicle strength to
protect passenger’s safety; and light-weight, aerodynamic design to increase fuel efficiency. Polycarbonate
makes much of this possible. Polycarbonate plastic moulded mirror housings, tail lights, turn signals, back-up
lights, fog lights, and headlamps all contribute to a vehicle’s unique style. Polycarbonate is also extensively
used in todays stylish automobile interiors.
Scratch and shatter resistant polycarbonate headlamp housings and lenses offer such superior features that
they have virtually replaced glass. Polycarbonate automotive lighting offers:
Weight savings (up to 1 kg per head light)
Increased safety due to a higher fracture strength
Increased design freedom making aerodynamically advantageous shapes possible
Ability to integrate many functional elements in the mouldings
The majority of today's bumpers are made of a combination of different plastics, including polycarbonate. More impact-resistant
than metal bumpers, plastic bumpers have a higher resistance to dents and are much less expensive to replace – and they don’t
rust!
Appliances & Consumer GoodsCustomers expect their appliances and consumer goods to look stylish while remaining functional and safe.
Customer perceptions have changed in the last decade and appliances such as electric kettles, fridges, food
mixers, electrical shavers and even hairdryers have all become fashionable status symbols in the home.
Polycarbonate plastic and its blends have made a large contribution to this change of perception due to its
moulding flexibility, styling and colouring possibilities while fulfilling all safety requirements such as heat
resistance and electrical insulation.
Electrical & ElectronicsCell phones, computers, fax machines, and pagers all keep us in touch with our businesses, families and friends
– and provide life assuring and life saving communication in an emergency. Polycarbonate is integral to the
electronic age. Light weight, yet impact and shatter resistant, polycarbonate has contributed to making
computers and cell phones weigh grams instead of kilos, while at the same time withstanding the bangs,
scratches and accidental drops of everyday use. It is also transparent making electronic data easy to read, yet
protected by a clear, hard shell.
Polycarbonate's properties of impact resistance, electrical resistance, heat resistance, dimensional stability
under varying environmental conditions, low weight and transparency make it highly desirable for use in
distributor boxes, fuse boxes, circuit breakers, cable sockets, displays, relays, LEDs, safety switches, high
voltage plugs and fluorescent lighting diffusers.
Glazing & sheet What do greenhouses and the dome of the Sydney Olympic stadium have in common?Polycarbonate sheet
glazing. Polycarbonate sheets are super-light, virtually unbreakable and can provide heat insulation, making
them ideal for roof glazing. In many greenhouses and conservatories multi-wall polycarbonate sheets
contribute to energy savings. Polycarbonate can be used when you need a material you can see through, but is
tough enough to withstand abuse.
As polycarbonate sheets are virtually unbreakable, protective paneling and glazing is frequently installed
wherever people and property need to be protected from injury and damage. In factories many workers are
protected by polycarbonate safety guards. Spectators at ice hockey games have a perfect view of the game
from behind protective polycarbonate glazing panels and bank employees are protected behind bullet-resistant
polycarbonate windows. Protective barriers and shields made of polycarbonate also guard taxi drivers and riot
policemen.
Leisure & SafetyIncreased safety awareness has become commonplace with today’s busy, action filled lifestyles. Protective
accessories are not only important but are often a legal safety requirement on the roads for cyclists or on
construction sites for builders. For example, wearing a helmet reduces your risk of head injury by 85 percent.
Growing demand from sport lovers for a high level of safety and maximum comfort, while participating in sports
(particularly "extreme" sports) has resulted in the development of today's super-lightweight helmets combining comfort, style and
protection. Polycarbonate is frequently used for the tough, shatter-resistant, moulded outer shell of helmets as well as providing
the transparent visors. This provides a smooth, aerodynamic surface and helps protect your head from nasty collisions and falls.
In addition, polycarbonate has enabled lenses to be lightweight and shatter resistant while offering tremendous design freedom
for a variety of sports and leisure goggles, fashionable sunglasses, skiing goggles, cycling goggles. Toughness, as well as
polycarbonate’s weathering resistance and its dimensional stability, makes it well suited for many other outdoor applications such
as compass and binocular casings, ship’s lights and ski boot buckles.
Medical & HealthcareNewly born babies are so vulnerable. Thankfully, plastic incubators provide a protected environment to keep
them safe from infection and cold. The incubator dome is formed of a tough, transparent plastic such as
polycarbonate so parents, doctors and nurses can watch and care for the baby safely. Smooth polycarbonate
surfaces are easy to keep clean and can withstand disinfectants. Moulded-in openings allow doctors and nurses
to care for the baby without letting the warmth out or infection in. The moulded openings also allow parents to
hold and feed their babies while keeping them safe.
Life saving modern medical treatments rely on aids such as kidney dialysers, blood oxygenators, tube
connections and many other components. Providing patients the protection they deserve, polycarbonate
medical devices are reliable in a wide range of environments and fracture resistant even after repeated
sterilisation. Due to its transparency, polycarbonate is excellent for oxygenators, dialysers and infusion units
allowing easy detection of life threatening air bubbles.
Corrective eyeglass lenses made of polycarbonate are becoming more and more popular due to their low
weight, which makes them comfortable to wear. Virtually unbreakable, polycarbonate lenses protect as well as
correct vision. Polycarbonate can even be used to fashion corrective goggles for snorkeling and scuba-diving
have allowed glasses wearers to see the wonders of the sea for the first time!
Bottles & PackagingPolycarbonate contributes to day-to-day safety in the home by providing unbreakable and shatterproof food
and beverage containers, baby bottles, water cooler bottles and milk bottles. Offering high transparency, but
lighter and stronger, polycarbonate is increasingly replacing the use of glass in such applications. Plastic food
containers and bottles also play an important role in protecting us against food borne illnesses. Millions of
people use polycarbonate containers every day to protect food against spoilage and contamination - keeping
us safe while helping our food stay fresh longer.
Tough polycarbonate bottles, containers and tableware, can withstand extreme stress during use and cleaning,
including sterilisation. They can be used to serve, freeze and reheat food in the microwave making them time
and energy savers. Shatterproof and virtually unbreakable, polycarbonate is a safer alternative to glass making
it a favorite for baby bottles, as well as being more convenient for parents on the go.
In addition, the lower weight and the efficient utilization of space, which is possible with square bottles made of
polycarbonate, allows more refillable containers of milk and other beverages to be transported with less use of
energy. The square bottles also fit more easily into refrigerator shelves.
Polyolefins
Polyolefins is the collective description for plastics types that include
polyethylene - low density polyethylene (LDPE), linear low density
polyethylene (LLDPE) and high density polyethylene (HDPE) - and
polypropylene (PP). Together they account for more than 47% (11.2 million
tonnes) of Western Europe’s total consumption of 24.1 million tonnes of
plastics each year.
Polyolefins are produced from oil or natural gas by a process of
polymerisation, where short chains of chemicals (monomers) are joined in the
presence of a catalyst to make long chains (polymers). Polymers are solid
thermoplastics that can be processed in two ways – by film extrusion or
moulding. During film extrusion the polymer is heated and forced, in a molten
state, through a die to produce thick sheet, thin film or fibres. The thickness of
the film can be varied to produce anything from lightweight food packaging
wrap to much heavier film for agricultural use. The moulding process involves
heating and compressing the polymer in an extruder, and then forcing it into a
mould where it solidifies into the required shape.
Benefits of polyolefins
Because of their versatility, Polyolefins are one of the most popular plastics in use today. Their many applications include:
LDPE: cling film, carrier bags, agricultural film, milk carton coatings, electrical cable coating, heavy duty industrial bags.
LDPE: stretch film, industrial packaging film, thin walled containers, and heavy-duty, medium- and small bags.
HDPE: crates and boxes, bottles (for food products, detergents, cosmetics), food containers, toys, petrol tanks, industrial
wrapping and film, pipes and houseware.
PP: food packaging, including yoghurt, margarine pots, sweet and snack wrappers, microwave-proof containers, carpet
fibres, garden furniture, medical packaging and appliances, luggage, kitchen appliances, and pipes.
PolystyreneThe terms Styrenics or Styrenic Polymers are used to describe a family of major plastic products that use Styrene as their key
building block. Included in this family of products are:
How is PS manufactured?How is polystyrene made ... and processed?
The building block - monomer - of polystyrene is styrene. The raw materials to make styrene are obtained from crude oil. A range
of processes such as distillation, steam-cracking and dehydration are required to transform the crude oil into styrene. At the end
polystyrene is produced by polymerising styrene. The final product is available in the form of pellets. In order to get the final
articles polystyrene pellets are extruded, thermoformed or injection moulded. Extrusion is a process in which the pelletised
polymer is melted and then forced continuously through a die to form an endless profile of polymer. Most of the time polystyrene
is extruded into sheet. In a second step this sheet can be thermoformed into the final article. Applications of thermoformed
articles include disposables such as cups and plates, meat and poultry trays, multiple and single-serving food containers in dairy,
vending machine cups, trays for hospital and restaurant use. Injection moulding is a process by which polymer is melted and
injected in a mould cavity, which after cooling down solidifies into the shape of the mould. Typical injection moulding applications
are housing of televisions, jewel boxes for compact discs, toys and innumerable other uses.
PVCPVC (Polyvinyl-chloride) is one of the earliest plastics, and is also one of the most extensively used. It is derived from salt (57%)
and oil or gas (43%). PVC is made from chlorine – produced when salt water is decomposed by electrolysis – with ethylene, which
is obtained from oil or gas via a ‘cracking’ process. After several steps, this leads to the production of another gas: vinyl chloride
monomer (VCM). Then, in a further reaction known as polymerisation, molecules of VCM link to form a fine white powder (PVC).
This powder is mixed with additives (stabilisers and/or plasticizers) to achieve the precise properties required for specific
applications. The resulting PVC granules (compounds) or ready-to-use powders (pre-mixes) are then converted into the final
product.
The benefits of PVC
PVC’s combination of properties enables it to deliver performance advantages that are hard to match. This material is durable
and light, strong, fire resistant, with excellent insulating properties and low permeability. By varying the use of additives in the
manufacturing of PVC products, features such as strength, rigidity, colour and transparency can be adjusted to meet most
applications, including:
Packaging, for toiletries, pharmaceuticals, food and confectionary, water and fruit juices, labels, presentation trays.
Leisure products, including garden hoses, footwear, inflatable pools, tents.
Building products, including window frames, floor and wall coverings, roofing sheets, linings for tunnels, swimming-pools
and reservoirs.
Piping, including water and sewerage pipes and fittings, and ducts for power and telecommunications.
Medical products, including blood bags, transfusion tubes and surgical gloves.
Coatings, including tarpaulins, rainwear, and corrugated metal sheets.
Insulation and sheathing for low voltage power supplies, telecommunications, appliances, and automotive applications.
Automotive applications, including cables, underbody coating andf interior trimmings
PVdCPVdC (Polyvinylidene Chloride) is a highly effective barrier coating polymer that is produced by the polymerisation of a vinylidene
chloride monomer with other monomers such as acrylic esters and unsaturated carboxyl groups. It is the chemistry, density and
symmetry of the molecules in PVdC that give the material its excellent barrier properties against fat, vapour and gases. This
molecular structure results from the combination of salt (50-70%) and oil (30-50%).
PVdC’s outstanding barrier properties make it ideal for use in food packaging, and it is particularly effective for products with a
high fat content and strong flavours and aromas. It is often used in the packaging of confectionary, dehydrated foods, dairy
products, sausages, patés, meat, smoked fish, and dried products such as herbs, spices, tea and coffee.
The benefits of PVdC
PVdC is a favourite material among designers because it delivers tangible and distinctive solutions to packaging needs. These
include:
High levels of transparency offer the most attractive product presentation and display. In applications where light
penetration can pose problems (medicines fro example), the PVdC film can be colour-toned to reduce exposure.
Excellent barrier qualities extend the shelf life and conservation of foods, while at the same time reducing the need for
preservatives, which in turn enhances the appeal of the product to the consumer.
Outstanding heat sealing properties help materials such as paper, cellophane and other plastics to seal themselves
effectively. This means that packaging can be easily and rapidly sealed during processing, so that high film speeds and
throughputs can be achieved.
Highly flexible characteristics allow the PVdC to perform across a very wide range of applications.
Unsaturated polyester resinsThey are typically used in combination with a reinforcement material like glass fibre to form a Fibre Reinforced Plastic (FPR),
which has excellent characteristics that include:
Light weight
High strength-to-weight ratio (kilo-for-kilo stronger than steel)
Rigid
Resistant to chemicals
Good electrical insulating properties
Retention of dimensional stability across a wide range of temperatures
These resins are used over a broad spread of industries. They have transformed the boat-building industry, especially the leisure
boat sector, by providing greater flexibility, superior performance and faster production speed. In the automotive industry, FRP
materials bring design freedom, low weight, mechanical strength and reduced system costs to the table. In the construction
industry, FRP is used in everything from roof tiles to finished surfaces for kitchens and bathrooms. It also offers an attractive
alternative to conventional materials in large projects such as building bridges and wind generators, where light weight, low
maintenance and high durability are highly desirable characteristics.

FAQ'sQuestions and Answers
What is styrene?
Styrene is a liquid that is derived from petroleum and natural gas by-products, but which also occurs naturally. Styrene helps
create plastic materials used in thousands of remarkably strong, flexible, and lightweight products that represent a vital part of
our health and well being. It's used in everything from food containers and packaging materials to cars, boats, and computers.
The styrene used in these products is synthetically manufactured in petrochemical plants. However, styrene also occurs in the
environment and is a natural component of many common foods, such as coffee, strawberries and cinnamon. Some people
confuse styrene, which is a liquid, with polystyrene, which is a solid plastic made from polymerised styrene. Styrene and
polystyrene are fundamentally different. Polystyrene is inert, and has no smell of styrene, therefore polystyrene often is used in
applications where hygiene is important, such as health care and food service products.
Is styrene present in polystyrene?
Very small amounts of styrene monomer that was not converted into polystyrene during processing do remain in finished
polystyrene products. Numerous studies and investigations have been carried out to determine if there is a safety concern
regarding the amounts of styrene that remain in polystyrene resins. The results of these studies indicate that polystyrene is safe
for use in food-contact products. Styrene is approved for use as a starting material for the production of polystyrene food and
beverage packaging by regulatory agencies worldwide. The European Food Safety Authority has not assigned a so called 'Specific
Migration Limit' to styrene. Many surveys made from e.g. the UK Ministry of Agriculture, Food and Fisheries (MAFF) in the late 90-
ies gave complying values for food packaged in polystyrene. This survey was repeated in 2003 and gave again complying values.
For more information see link: www.food.gov.uk/news/newsarchive
Do I come into contact with styrene?
Styrene is a natural component of some foods, and is present in small amounts in foods such as cinnamon, beef, coffee beans,
peanuts, wheat, oats, strawberries, and peaches. Most people are exposed to styrene in tiny amounts that may be present
naturally in the diet, air (styrene is a component of cigarette smoke,gasoline and fuel exhausts, and, in trace quantities, as a
result of using food-service packaging). Scientific studies have shown that the very small amount of styrene that people may be
exposed to from packaging is about the same amount as comes from naturally-occurring styrene in foods. These studies have
also shown that these levels of exposure are safe and should not be a cause for concern.
Is styrene harmful to my health?
Styrene is harmless in the very small amounts most people might normally encounter in air or food. The general public is very
unlikely to encounter high levels of styrene. In fact, styrene is approved by the US Food and Drug Administration as a food
additive. Major studies in Japan, United States and Europe have shown that even at very exaggerated levels of exposure, the
oligomers (combination of two or three styrene molecules) that can migrate from polystyrene did not show an estrogenic effect.
For those directly working with the product (i.e. professional users, the people involved in the conversion of styrene into the final
items we use in the everyday life), the relevant safety measures are provided by means of a Safety Data Sheet. Governments and
Industry have set safe exposure limits for professional workers.
As part of a continuing effort to protect health and the environment, the European Union and the U.S. Environmental Protection
Agency are both currently conducting formal reviews that will provide safety assessments of the scientific data on styrene.
What about the odour of styrene?
Styrene's distinctive odour can be detected even when styrene is present at extremely low levels - levels that are many, many
times below any level that may result in a possible health effect.
Is there a concern about a risk of cancer?
Styrene is currently under European risk assessment to investigate its impact on the environment and human health. The general
population incurs no detectable risk resulting from styrene exposure. Existing work place exposure limits represent a satisfactory
precautionary measure to protect styrene-exposed workers.
Landfill is not an adequate solution for plastics waste; in fact, landfilling plastics waste simply means throwing oil away!
At the moment there is no uniform plastics waste management practice in the EU-27 countries; some countries are far ahead,
while others are way behind political targets. To effectively tackle this situation, PlasticsEurope has developed a knowledge
transfer programme, the main goals of which are to:
Communicate a vision on waste management that is widely accepted
Assist in providing our know-how and share our best practices regarding waste management
Make the general public aware that a proper plastics waste management scheme leads to resource
efficiency
Innovation
Although plastics have been around for about 100 years they are considered to be modern when compared to traditional
materials like wood, stone, metal, glass and paper. In recent decades plastics have enabled numerous technological
advancements, new design solutions, eco-performance enhancements and further cost-savings.
Nowadays, thanks to plastics, the only limitation for designers is their imagination. Diminishing natural and non-renewable
resources, climate change and an ageing and growing population are some of the main challenges for society to rise up to. If
plastics did not exist, we would probably need to invent to tackle thse issues.

Use of plasticsThe relatively low density of most plastic materials means the end products are lightweight. They also have excellent thermal and
electrical insulation properties. However, some can even be made as conductors of electricity when required. They are corrosion
resistant to many substances which attack other materials, and some are transparent, making optical devices possible. They are
also easy to mould into complex shapes and forms, allowing integration of different materials and functions. And in the event that
the physical properties of a given plastic do not quite meet the specified requirements, the property balance can be modified with
the addition of reinforcing fillers, colours, foaming agents, flame retardants, plasticisers etc., to meet the demands of the specific
application.
For these reasons and more, plastics are increasingly used in:
Packaging
Building and Construction
Transportation
Medical & Health
Electrical & Electronic
Agriculture
Sport & Leisure
Basically these plastics are man-made. In principle any combination of properties can be developed to accommodate almost any
application you can think of.
PackagingThe commercial success of plastics as a packaging product is due to a combination of flexibility (from film to rigid applications), strength, lightness, stability, impermeability and ease of sterilisation. These features make plastics an ideal packaging material for all sorts of commercial and industrial users.
Plastics food packaging, for instance, does not affect the taste and quality of the foodstuff. In fact, the barrier properties of
plastics ensure that food keeps its natural taste while protecting it from external contamination. Moreover, the
material's unparalleled versatility is demonstrated in a multitude of applications such as packaging films for fresh meats, bottles
for beverages, edible oils and sauces, fruit yoghurt cups or margarine tubs.
The following are just some of the benefits offered by plastics packaging:
The lightest packaging material: While over 50% of all European goods are packaged in plastics, these plastics account only for 17% of all packaging weight. Furthermore, this weight has been reduced by 28% over the past 10 years! Lightweight packaging means lighter loads or fewer lorries needed to ship the same amount of products, helping to reduce transportation energy, decrease emissions and lower shipping costs. It also helps reduce the amount of waste generated.Food conservation and preservation: Plastics packaging protects and preserves perishable food for longer. It helps reducing waste and the use of preservatives while maintaining the taste and nutritional value of food.
Convenient and innovative: nowadays people want packaging with clear identification and labelling which is easy to open and use. Plastics packaging evolves to provide exactly that. In the near future, for instance, it will integrate printable RFID (Radio-frequency identification) chips based on conductive polymers, providing precious information on the quality and status of products.
Safe and hygienic: Plastic packaging protects against contamination of foods and medicine and helps prevent the spreading of germs during manufacture, distribution and display. Tamper-proof closures provide additional protection and security, while transparent packaging allows people to look at food without having to touch it, cutting down on bruising and other damage.
Building & ConstructionIn 2010, the Building and Construction sector consumed 9.54 million tonnes of plastics (21% of total European plastics consumption), making it the second largest plastic application after packaging. Plastic pipes, for instance, command the majority of all new pipe installations, with well over 50% of the annual tonnage. And this share is still growing.
Although plastics are not always visible in buildings, the building and construction industry uses them for a wide and growing
range of applications including insulation, piping, window frames and interior design. This growth is mainly due to plastics'
unique features, which include:
Insulation
Plastics provide effective insulation from cold and heat, prevent leakages and allow households to save energy while
also reducing noise pollution.
TransportationWhen developing transport solutions, designers need to find the right balance between high performance, competitive pricing, style, reliability, comfort, safety, strenght, fuel efficiency and minimal environmental impact. The sustainable solution often lies in a new generation of lightweight plastics, because:
Plastic components weigh 50 percent less than similar components made from other materials, which means a 25 to 35%
improvement in fuel economy.
For every kilogram lost, your car will emit 20 kilograms less of carbon dioxide over its operating life.
Plastics bring lightweight solutions without prejudice of fire safety when assessed using engineering standards.
The aircraft industry is a good example of how plastics and design innovation are connected. Since the 70's, the use of plastics in
airplanes indeed grew from 4 to almost 30%, and should reach 50% by 2013!
In the automotive industry, plastics allow for energy absorption, weight reduction and innovative design while contributing to
passenger safety. Features such as shock absorption for bumpers, suppression of explosion risks in fuel tanks, seat belts, airbags
and other life-saving accessories such as durable plastic safety seats to protect our youngest passengers make plastics the safest
material for car-related applications.
Plastics are also in the vanguard of sustainable innovation, with the average car containing 120 kilograms of plastics (15 to 20%
of its total weight). Daimler Benz's SMART fortwo cdi, which was introduced at the Geneva Motor Show 2010, is a perfect example
of how innovation made possible with plastics also brings environmental benefits. The car features a range of high-quality
thermoplastics that bring design flexibility, but more importantly, the light weight of these plastics means that the car uses an
average of 3.3 litres of fuel every 100km and emits only 86g of CO2 per kilometre!
Electrical & Electronic
From simple cables and household appliances to smartphones and Blu-ray players, many of the latest devices created in the
Electrical & Electronic sector capitalize on new generation plastics.
Designers of electrical and electronic applications rely on plastics because of their unique features. These include :
Resource-efficiency: Polymers can help storing energy for longer, while LCD (liquid crystal display) flat screens made of liquid crystalline plastics use over 65% less power than ordinary screens with cathode ray tubes.
Light weight: Touch-sensitive screens on tablets and smartphones are created with films of polycarbonate In small appliances like smartphones and MP3 players, the use of plastics has increased along with the number of different polymer types being used. Smaller, lighter handsets are made possible thanks to plastics.
Resistance: The insensitivity of plastics to electromagnetic radiation, combined with their resistance to mechanical shocks, stress resistance, flexibility and durability, makes them ideal for vital applications such as safe, reliable and efficient power supplies.
Reduced size: While most plastics in electrical and electronic equipment are visible, the latter also contain many plastics components you cannot see. Nearly half of all the plastics used in this sector are used in sheathing for cables and in electronic components.
Fire safety: In the electrical and electronic equipment sector (EEE), where a fire can be ignited from electrical sources, flame retardants offer a large range of solutions for inhibiting ignition and are in widespread use. In most cases, a given polymer requires a specific formulation for each possible application.
Innovation: Thanks to ambitious research programmes, plastics in the electrical and electronic sector are constantly evolving. Lithium batteries, for instance, can now be made from recycled plastic bags. Plastic batteries made from conductive polymers have the significant advantage of offering high power with low weight. But plastic-related innovation also comes from their optical properties. With polymers used in optical switching, the flow of data can be facilitated over long distances between one chip and another.
Agriculture
For years, the growing use of plastics in agriculture has helped farmers increase crop production, improve food quality and reduce the ecological footprint of their activity. Not only do plastics allow for vegetables and fruits to be grown whatever the season, but these products are usually of better quality than those grown in an open field.
A wide range of plastics are used in agriculture, including, polyolefin, polyethylene (PE), Polypropylene (PP), Ethylene-Vinyl
Accetate Copolymer (EVA), Poly-vinyl chloride (PVC) and, in less frequently, Polycarbonate (PC) and poly-methyl-methacrylate
(PMMA). These plastics provide:
Innovative and sustainable solutions: Thanks to the use of different plastics in agriculture, water can be saved and
crops can even be planted in deserted areas. Plastic irrigation pipes prevent waste of water and nutrients, rain water can
be retained in reservoirs built with plastics, and the use of pesticides can be reduced by keeping crops in a closed space
such as a greenhouse or, for mulching, under a plastic film. Moreover, the emissions of pesticides in the atmosphere will
be reduced as they will remain fixed on the plastic cover.
Recycling and recovery opportunities: At the end of their life cycle, agricultural plastics such as greenhouse covers
can be recycled. Once retrieved from the fields, plastics are usually washed to eliminate sand, herbs and pesticides,
before being grinded and extruded into pellets. The material can then be used again in the manufacturing of articles such
as outdoor furniture. When recycling is not viable, energy can be obtained from agricultural plastic waste in a process
called co-combustion.
Key applications
Greenhouses: Greenhouses are like intensive-care units. Thanks to them, plants are exposed to the sunlight and can grow in ideal conditions according to their physiological properties. The use of greenhouses indeed provides farmers with the possibility to create the appropriate environmental conditions that plants require for faster and safer growth, to avoid extreme temperatures and protect crops from harmful external conditions.
Tunnels: Tunnels have the same features as greenhouses, except for their complexity and their height. Crops that are the most commonly cultivated in tunnels are asparagus, watermelon, etc.
Mulching: Mulching or covering the ground with plastic film helps maintain humidity as evaporation is reduced. It also improves thermal conditions for the plant’s roots, avoids contact between the plant and the ground and prevents weed from growing and competing with for water and nutrients.
Plastic reservoirs and irrigation systems: When combined, plastic reservoirs and plastic irrigation systems make an essential contribution to water management. Water can be stored in dams covered with plastics materials to avoid leaking and distributed via pipes, drop irrigation systems and systems for water circulation.
Silage: This application, which was developed to store animals’ grains and straw during the winter, is another proof of the value of plastics. Plastic films used to store silage are resistant and the content canbe stored for years.
Other plastic applications include boxes; crates for crop collecting, handling and transport; components for irrigation systems like fittings and spray cones; tapes that help hold the aerial parts of the plants in the greenhouses, or even nets to shade the interior of the greenhouses or reduce the effects of hail
Medical & Health
Modern healthcare would be impossible without plastics medical products we tend to take for granted: disposable syringes, intravenous blood bags and heart valves, etc. Plastics packaging is particularly suitable for medical applications, thanks to their exceptional barrier properties, light weight, low cost, durability, transparency and compatibility with other materials.
People are living better, longer and have increasingly fulfilling lives. Thanks to the endless versatility of modern plastics, medical
breakthroughs considered unthinkable 50 years ago are now regarded as commonplace.
Some applications
Unblocking blood vessels: In the latest heart surgery, thin tubes (catheters) are used to unblock blood vessels, while deposits obstructing them can be broken down with a tiny spiral-shaped implant - a vessel support. Positioned in the treated artery, it is made of a plastic developed specifically for the medical field and charged with active substances.
Prosthesis: Plastics are now being used as orthopaedic devices, where they align, support or correct deformities. they can even improve the function of movable parts of the body or replace a body part, taking over its main function. Synthetic material also plays a vital role for diseased arteries that cannot be helped via vessel support. An affected section of the aorta is removed and the gap is bridged by a flexible plastic prosthesis. Thanks to this, the body's lifeline becomes fully functional again.
Artificial corneas: Eye injuries or chronic inflammations, for example corneal erosion, can impair sight, and if a transplant has little chance of success, a prosthesis is the only hope. Artificial corneas made from special silicone are now available for treatment. Only 0.3 to 0.5 millimetres thick, highly transparent, flexible and made of bio-mechanics similar to a natural cornea, it can restore clear vision again.
Hearing aids: People with severely impaired hearing can now have a plastics implant that brings sound back in thier hears. This implant consists of numerous components - a microphone, a transmission device connected to a micro-computer worn on the body, a stimulator and an electrode carrier with 16 electrodes for 16 different frequency ranges. As it transforms acoustic impulses into electrical ones, it bypasses the damaged cells and stimulates the auditory nerve directly.
Plastics pill capsules release exactly the right dosage of its active ingredients at the right time. The tartaric acid-based polymer gradually breaks down, slowly releasing the active ingredients over a longer period of time. These tailor-made pharmaceuticals help to avoid having to frequently take large quantities of pills.
Sport, Leisure, Design
Plastics have revolutionised sports in recent years. From tracks on which Olympic athletes pursue new records to shoes, clothing, safety equipments (helmets, kneepads) and stadium construction (water and drainage pipes, seats, roofing), modern sports rely on plastics. Here are some examples application :
Plastics in ballgames: Plastics materials are used in almost all types of ballgames. Thanks to plastics, football for instance has become faster and more technical than ever before. The newest ball production concept - called thermal bonding and using a high-solid polyurethane layer on a seamless glued surface – results is an excellent responsiveness and ball contact sensitivity, a predictable trajectory, substantially reduced water uptake and maximum abrasion resistance.
Plastics in sports footwear: Running shoes that weigh just a few grams yet provide the strength and suppleness that athletes demand as they power out of the running blocks can make the difference between victory and defeat. Plastics play an important role in today’s sports shoe designs, whether the application is running, jumping or hiking. Take hiking boots for example; the lining and tongue can be made from a loosely woven polyester fabric that repels water and allows moisture to rapidly evaporate from the boot’s exterior, keeping the hiker’s feet dry in the wet and cool in the heat. For comfort and support, the mid-sole can be made from ethyl vinyl acetate (EVA), which provides lightweight cushioning. Polyester foam padding, on the other hand, provides extra comfort on the insoles.
Plastics in tennis: Today, sports manufacturers use plastics to make tennis racquets that are light and strong, with excellent shock-absorbing systems. Players now have more powerful racquets with increased ease of manoeuvrability. In some racquet models, the central longitudinal strings are lead through a specially developed plastics core that is embedded in a plastics composite, which reduces shock vibration by 45% when the ball hits the racquet. This innovative technology allows tennis enthusiasts at all levels to enjoy the benefits of plastics on their local courts.
Plastics on water: The mouldability of composite plastics enables sleek dynamic hulls to be produced that are low in weight and high in strength. Power cruisers, sailing yachts and almost every other vessel now has a hull, deck, superstructure and even a mast made of composites. Today’s yachts use advanced carbon fibre compounds that helps taking yacht racing to a new level. This innovative plastics compounds has largely replaced traditional materials building methods by providing greater flexibility, superior performance and faster production speed.
Plastics and children: For close to 50 years, the world's toymakers have been using plastics to make some of the best known and most popular toys and products for childrens. From bicycle helmets and flotation devices to kneecaps and other protective sporting gear, plastics help keeping children safe everyday. Plastics are one of the most thoroughly tested, well-researched, durable, flexible and cost-efficient materials on today's market .
The European plastics industryThe European plastics industry - plastics producers, converters and machinery manufacturers - are a major contributor to the
European economy. The industry directly employs some 1.6 million people and many more that work in industries relying on
plastics for their business. Together the different parts of the industry contributed around 13 billion euro in trade surplus to the
EU27 economy in 2008 - helping to reduce an overall industrial trade deficit of over 240 million euros.
PlasticsEuropePlasticsEurope is the only European trade association headquartered in Brussels with representatives across all European Union’s 27 member states. PlasticsEurope has developed close partnerships with sister associations that represent the European plastics manufacturing chain, which includes 50,000 converters and over 1,000 machinery manufacturers as well. PlasticsEurope is the official voice of the European plastics manufacturers.
PlasticsEurope has more than 100 member companies, producing over 90% of all polymers across the 27 EU member states plus
Norway, Switzerland, Croatia and Turkey.

Mission and values
Our mission for plastics
The reason plastics have steadily replaced many traditional materials is because they offer many improvements in performance
(reduction in the consumption of scare resources, a reduction in energy requirements, a lower cost)
Plastics are also inherently capable of meeting the needs of sustainable development. Economically: they provide cost-efficient
market solutions. Socially: they have been developed with little compromise – to perform exactly as is required to meet society’s
growing demands. Environmentally: performance can now be matched with ensured safety in use and managed environmental
impact in production and at end-of-life.
Plastics are now an essential part of our world. If they did not already exist, society would have to invent a material with all of the
same properties to enable our survival. Continuous development and improvement of what these amazing materials can do, and
how we manage them throughout their lifecycle will ensure that they continue to add value for us.
Therefore, as an industry, we see plastics' mission as being simply:
"to meet people’s needs better”
PlasticsEurope's values
Innovative: Our industry's pioneering outlook and our courage to face challenges and innovate, allows us to take advantage of
opportunities and find new solutions.

Plastics the Facts
The plastics industry – comprising PlasticsEurope, EuPC, EuPR and EPRO – publishes an annual report on trends in production,
demand and recovery of plastics called the "Plastics - the Facts”. The report can be downloaded in pdf format or ordered in
printed form.
Standardisation
We are all used to standards: you can consult your bank account, withdraw money from a cash dispenser or go shopping around
the world with just your credit card because it is ‘standardised’ and follows international protocols. Similarly, the plumber can buy
a PVC pipe for drinking water in Finland and it will fit a PVC valve bought in Italy because their diameters have been standardised
according to a European standard – in this case EN 1452.
We can find another good example of standardization in packaging. In order to comply with legislation, a plastic packaging item –
bottle, tray, film, etc- meant to be in contact with foodstuff has to demonstrate that it is safe for consumers use. The only way to
demonstrate this is by adhering to a standard. This standard describes the test method for, e.g., the determination of overall
migration of substances from the packaging into a food stimulant, for example olive oil.
But plastics cover almost every application we can imagine so our materials and products are affected and come under many
standardization activities. From very specific ones, like the examples already given, to more general ones, like the carbon
footprint of products.
Standards are developed as voluntary agreements, made in an open and transparent way and are the result of consensus.
Typically standards exist at three levels: National, European and International.
At the European level, legislation impacting our industry is driven more and more by the EU and requires transposition at the
national level (Parliament/Council) – 65% of new laws come from Brussels.
A new regulatory strategy has been introduced by the Council Resolution of 1985 on the "New Approach” to technical
harmonization and standardization. The New Approach relies on mandates from the European Commission to the European
standardization bodies CEN, CENELEC and ETSI giving these standards legally binding power or making them compulsory. That is
one of the reasons for the importance of being involved in the standard making-process.
Public concern around environmental, safety and health issues has grown enormously and has influenced policy and regulation.
The European Commission wants to involve all stakeholders in order to integrate environmental aspects into European
Standardization. This position has resulted in a greater involvement of consumers and environmental NGOs. This is another
reason to be attentive to standardization and to provide the proper industry input.
Not only at the European, but also at a global level, business to business relations are based on agreements which conform to
international standards, as e.g. in the automotive and E&E sectors, fire safety issues or for publicp. This is another reason to be
involved in standardization.
Standardization has always been a complex matter to coordinate from a global perspective. Each of the three levels of
standardization: International, European and National are very important but have to be approached differently.
Now, with the incorporation of new member states into the European Union, the standardization playing field is broadening and
offers more chances for the plastics industry but which, at the same time, needs to be better organized: participation of
companies in national standardization bodies, creation of national mirror groups etc. PlasticsEurope, being aware of the
relevance, standardization has, for the industry, has created the Standardization Working Group to identify relevant
standardization issues and to encourage participation of the members.
Plastics & Sustainability
The plastics industry aims to be a responsible partner to policy-makers and other stakeholders in finding solutions to the
crucial issues of climate change, energy and resource efficiency, consumer protection and waste management. Plastics have
a great potential to help deal with these issues and this is the reason why PlasticsEurope is working closely with the value chain
to develop a common plastics industry vision and approach.
Plastic plays a major role in delivering and sustaining the quality, comfort and safety of modern life-styles. Its impressive ratio of
cost to performance also means that people of all income groups can enjoy these benefits. But meeting the needs of society is
not just about ''today''. Future generations also have the right to material and other benefits. Meeting the needs of tomorrow is
the foundation of the concept of ‘Sustainable Development’. Plastic products are already helping every day to improve people’s
lives, whilst conserving natural resources and helping to protect the environment for tomorrow, in a world that is growing in
population, with ever-increasing demands for water, food, shelter, sanitation, energy, health services and economic security.
Consumer protection
From safety to food conservation and cost-efficiency, plastics protect consumers in many ways while also providing them with
sustainable solutions. In packaging applications, for instance, more than 50% of products are packaged with plastics. However,
plastics account for only 17% of total packaging weight and therefore help reach greater resource efficiency.
Constantly doing more with less, plastics also tend to reduce their use of raw materials. Plastic bags indeed require 70% less
material today than they did in the 80s. Not only does it increase resource efficiency, but it also provides consumers with
increasingly cost-efficient solutions.
Then, thanks to their unique features, plastics also reduce food waste by extending shelf life, preserve food taste and protect it
from bacteria while also providing unique protection to non-food products. This all results in additional comfort for consumers and
in a substantial reduction of thier environmental foodprint.
Packaging is just but an example of application where plastics combine consumer protection with sustainable solutions. For
instance:
We use plastic pipes to carry our drinking water safely and efficiently, and to get rid of sewerage
Many of the toys our children play and of the applications they use daily are made of plastics. Plastics’ strength, light
weight, versatility and malleability contribute to children safety.
Plastics also help in fire safety, with firemen helmets and suits being the best example of their contribution.
In our cars, lightweight plastics are used to protect us, enhance our comfort and increase fuel savings
In sports, plastics provide consumers with efficient, light and strong safety gear.
REACH
The EU Chemicals Policy, known as REACH (Registration, Evaluation and Authorisation of Chemicals) entered into force on June
1st, 2007 (EC1907/2006). It has a direct impact on every member of the plastic supply chain, including additives producers,
plastics producers, plastics converters and retail businesses.
Substances of interest to the plastics industry
Total: 14 substances Monomers: 3.
Not subject to authorisation (intermediates) Pigments: 3
Lead chromates (Red and yellow + mixtures) Flame retardants: 3 Phthalates: 4 (PVC plasticisers and components of PP catalysts) Catalyst: 1 (HDPE cata)
Exposure Scenarios
PEST (Plastics Exposure Scenario Team) formed by the most important associations representing the plastics supply chain
has produced a list of Generic Exposure Scenarios that cover most of the known plastics uses and has translated them into
"REACH use descriptors”.
To access the table, click on the image below
These use descriptors should be used by the plastics producers to communicate with their suppliers to inform them of their uses. This is recommended for classified additives and facultative for the non-classified ones.
ES for registrants of substances used as additives in plastics
A web based tool is now available to the M / I of substances used as additives in plastics. It allows them to easily evaluate the safe
conditions of use of their substances, both for the human health and the environmental end points.
The access to the site is limited to the members of the associations part of PEST. This means that if, as a member of
PlasticsEurope, you need to register an additive and evaluate its safe conditions of use, you have the right to use the site. Just
take contact with Claude Palate to get a password key that will allow you to register on the site and use it.
The second phase of the project is already launched. It will give the possibility to evaluate the use of classified substances
(additives) in the use phase when they are added to a plastic, a compound or a master-batch. It will even be possible to assess
blends of classified substances. This step will thus cover typical compounding activities of PlasticsEurope members. It
will be particularly useful in case of classified compounds (due to the presence of one or more classified additives) and will allow
producing the details of the ES, to be put as annex to the SDS. It is expected that this development will become available end of
2010 / beginning of 2011.
All the ES are based on the ECETOC TRA tool, Tier 1 for the workers exposure and Tier 2 for the environmental impact (including
the OECD default parameters of the different plastics families covered). The latter is particularly interesting as it provides with not
too conservative results, a very positive point as the tools recommended by ECHA are in general very conservative. The workers
exposure scenario does not benefit from this feature and the use of a scaling tool (that will also be available on the website) will
in many cases be necessary.
Climate protection
PlasticsEurope is an official Associate of the Sustainable Energy EU Campaign, as part of the plastics industry's
efforts to contribute to an increasingly energy efficient society. Sustainable development is one of the driving forces
for acting responsibly to protect the world’s resources for future generations and plastics play a key role in the area.
Plastics and the Climate Change Paradox
Plastic products account for the use of just 4% of the World non-renewable fossil fuel consumption but, paradoxically,
increased use of plastics would actually reduce the overall consumption of non-renewable fossil fuels and reduce society’s
GHG emissions. Contrary to popular belief, reduced use of plastics would actually have the opposite effect - increasing the
overall consumption of non-renewable fossil fuels and increasing society’s GHG emissions.
Resource efficiency
Making the most of our planet's limited resources is now one of the key challenges our society has to rise up to. In light of this
evolution, plastics can bring sustainable solutions provided that their use is supported by appropriate policies, infrastructure and
consumer behaviours. Plastics can indeed:
Do more with less: plastics account for 50% of product packaging while representing only 17% of its overall weight.
Therefore, thanks to the growing use of plastics in the packaging sector, less material is required to do more. Plastics
also help products reach consumers undamaged, properly sealed, maintained at an appropriate temperature and in the
case of food products, kept fresher for longer.
Improve resource efficiency: using raw materials such as oil and natural gas to make plastics is much more resource-
efficient than burning them to create energy, as their life cycle is substantially extended. Moreover, the resources used to
produce plastics are progressively decreasing. In Germany, for instance, to produce the same amount of plastics the
industry reduced its consumption of oil (from 1.4 to 0.5 million tonnes), coal (from 0.9 to 0.3 million tonnes) and gas (from
6 to 5.8 million tonnes) between 2000 and 2005. Equally the weights of plastic products are reducing, e.g. for plastic
carrier bags, the amount of plastics used has been reduced by 70% since the 1980s.
Be banned from landfills: with today’s focus on resource efficiency there is strong evidence to argue that plastics are a
resource that is too valuable to be thrown away. Landfill is not an appropriate solution for plastics waste. In fact,
landfilling plastics waste simply means throwing oil away!
At the moment there is no uniform plastics waste management practice in the EU-27 countries; some countries are far ahead,
while others are way behind political targets. To address this imbalance PlasticsEurope has developed an ambitious Knowledge
Transfer Programme. Within this framework, our role is to communicate a vision of waste management that is in line with the EU
waste hierarchy policy, to spread the industry's know-how and share information on our best practices regarding materials sorting
and recycling.
Finally, we aim to make the general public aware that a proper plastics waste management scheme leads to greater resource
efficiency. PlasticsEurope advocates for plastics to be recycled where it is both economically and environmentally viable to do so.
But for those products where this is not an option, their energy should be recovered through the use of advanced thermal
processes such as combined heat and power, or converted into new plastics and fuels.
Plastics Recycling
Many types of plastics can be recycled. PVC, for example, is one of the most versatile plastics and is the 3rd most used in the
world. It is also one of the most recycled; 72% of all collected PVC waste from windows and 67% of used PVC pipes are recycled.
Industrial packaging films made from polyolefins are also recovered and recycled. Think of products as diverse as shopping bags,
bottle crates, food containers, sacks for agricultural products, water pipes and windscreen wipers; all made from polyolefins, and
all suitable for some form of recovery.
Plastics recovery
Plastics that can’t easily be recycled are still a valuable energy source. The cement industry, for example, began using high-
calorific plastics waste for generating heat in the mid-1990s. Since then, the amount of plastics used as a fuel source for making
cement has increased ten-fold. Studies have shown that using plastics for generating heat in this way not only provides economic
advantages, but also provides environmental benefits.. Used plastics are also a very cost-effective and efficient way of providing
heat and electrical power in cities around Europe, which reduces land-fill space and helps save the environment.
PlasticsEurope supports the diversion of ‘calorie rich’ plastics waste from landfill and actively promotes the end-of-life
management of this material through recycling or recovery to achieve the most eco-efficient solution. Eco-efficient waste
management of plastics is part of an integrated waste management system; all options (mechanical recycling, feedstock
recycling and energy recovery) are needed
Waste in automotive
In the past, the presence of large homogeneous waste streams has meant that for the transport sector, mechanical recycling
focused on removing the large parts for recycling. Apart from 8 to 9 kilotonnes of bumpers, which are relatively easy to dismantle
and separate, the recycling of other car parts has been difficult to develop. As the EU ELV directive came into force, and the
industry began to concentrate on implementation, PlasticsEurope started to explore new techniques to improve end of life
recovery. The limited availability of homogeneous and clean waste streams for mechanical recycling means interest in shredder
residue treatment is now becoming even more important. To demonstrate the eco-efficiency of plastics, research across the
whole life cycle of plastics, from 'cradle-to-grave', will continue to play an essential role in shaping future legislation. In particular,
as revision of ELV recycling targets begins, PlasticsEurope will again be proactive in contributing studies to help guide this
legislation.
Energy savings
With the EU committing to saving 780 million tonnes of CO2 by 2020, our society has entered a period of major change where
decision-makers, industries and consumers will have to work hand-in-hand towards greener living standards. For PlasticsEurope,
this ambitious goal cannot be separated from the efficient use of energy. This is something the plastics industry can contribute to
achieve, thanks to:
Efficient insulation: in buildings, plastics provide effective insulation from cold and heat and
prevent air leakages. Plastic insulation materials consume approximately 16% less energy and
emit 9% less GHG than alternative materials. Across their whole life cycle, plastic insulation
boards save 150 times the energy used for their manufacture.
Applications in the generation of renewable energy: Did you know that wind turbines'
rotor blades and photovoltaic panels contain large amounts of plastics? Thanks to these major
contributions to the efficient production of renewable energy, plastics can help save 140 times
and 340 times respectively, the emissions produced during their production.
Prevention of food losses: plastics food packaging
delivers more efficient protection, reduces food waste and extends shelf life, thereby saving
energy and GHG emissions. Plastics packaging for meat, for instance, extend shelf life by three
to six days and even longer for the most advanced ones. Considering that producing one kilo of
beef leads to emissions equivalent to three hours of driving, this extended shelf life is a substantial improvement for our
planet!
Lightweight applications: plastics also provide lightweight packaging and vehicle weight
reductions that combine to result in less CO2 emissions linked to transportation. Replacing plastic
packaging with alternatives would lead to packaging weight being multiplied by a factor of four if
alternative packaging materials were used!
Less greenhouse gas emissions at production level: most plastic products need less
energy to be produced than other materials, especially in applications such as transport, building
and construction, packaging and electronic devices. If plastics had to disappear and to be
replaced by alternatives, the life-cycle energy consumption for these alternatives would be
increased by around 57% and the GHG emissions would rise by 61%.
Clearly the use of plastics helps reduce energy, costs and greenhouse gasses.
Life Cycle Thinking
PlasticsEurope promotes the use of Life Cycle Thinking (LCT) to improve understanding about product benefits and to take more
informed decisions. As a scientific method, Life cycle assessment (LCA) is a technique to analyse the potential environmental
impacts associated with a product, process or service. It involves:
Compiling an inventory of energy and material inputs and environmental releases
Assessing the potential environmental impacts associated with identified inputs and releases
Calculating performance indicators to inform decisions.
Learn more about how PlasticsEurope applies LCA and find links to additional resources.
Eco-profiles Programme
PlasticsEurope was the first industry organisation to assemble and publish detailed environmental data on the processes operated
by its member companies. The first Eco-profile reports were published in 1993. Since then, more reports have been added and
continuously updated, so that there are now more than 70 Eco-profile reports freely available. In 2006, a complementary
Environmental Product Declaration programme was begun. Eco-profiles and EPDs cover the high volume, bulk polymers, some of
the more widely used engineering plastics and several common plastics conversion processes. Widely acknowledged among life
cycle practitioners and other stakeholders worldwide as representative datasets, they have been included in various commercial
life cycle databases as well as in the publicly available European Life Cycle Database (ELCD).
Objectives of Eco-profiles
PlasticsEurope has clear objectives when compiling the Eco-profile reports, representing European production averages:
One, is to place scientifically sound data in the public domain for use in product life-cycle studies, without compromising
the confidentiality of detailed process data of the individual companies.
The second is to encourage environmental improvements in production processes through benchmarking against a
European industry average.
The third key factor is that, given the large contribution of upstream effects to the Eco-profile of a polymer and in view of
the distribution of input materials, such as ethylene or naphtha via the European pipeline network, industry averages are
the most robust representation of polymer production systems.
Future of Eco-profiles
Since the first Eco-profile reports were published, the Life cycle assessment methodology, standardisation and practice has
undergone substantial changes. New concepts, such as Environmental Product Declaration (EPD) and Carbon Footprint have
emerged. Downstream industries like the building and construction sector have their own standards and data needs. Hence, Eco-
profiles need to change in response to best practices and stakeholder needs. To this end, PlasticsEurope periodically seeks
stakeholder input on the Eco-profile methodology. Furthermore, in view of the need for globally harmonised practices and
comparable results, PlasticsEurope welcomes and actively invites liaison with other regional federations. As a contribution
towards shared best practices, the Eco-profile methodology aligns with other material- or sector-specific standards.
Environmental Product Declarations
Based on the Eco-profiles, PlasticsEurope also provides Type III Environmental Declarations according to ISO 14025, commonly
called Environmental Product Declarations (EPDs). The EPD programme is governed by the following:
General Instructions for the Environmental Declaration Programme - September 2007
The PlasticsEurope Methodology Document (see sidebar) also includes the Product Category Rules (PCR) which define how to
calculate EPDs from the Eco-profile datasets. Given the more recent nature of the EPD programme, EPDs are available for many
polymers, but not yet for all. Where no EPD is available yet, the Eco-profile report includes figures on Global Warming Potential
(Carbon Footprint). All updated Eco-profiles comprise the EPD as an introductory section
Applicable standards
PlasticsEurope considers the recognition and use of the ISO 140xx series of standards to be very important when using Life Cycle
Thinking in the decision-making processes involving environmental criteria.

Marine Litter
Global Plastics Associations Take Action on Marine Litter
The European plastics industry has been instrumental in bringing together 47 plastics industry organisations from around the
world to sign up to a "Joint Declaration for Solutions on Marine Litter”, which was announced at the 5th International Marine
Debris Conference in Hawaii in March 2011.
The Declaration outlines a set of clear objectives for industry action, and advocates close cooperation with a broad range of
stakeholders to achieve substantial progress in reducing damage to the marine environment.
In the six-point strategy outlined in the Declaration, the industry will:
Work in public-private partnerships aimed at preventing marine debris
Work with the scientific community to better understand the scope, origins and impact of marine litter and the range of
solutions to the problem
Promote comprehensive science-based policies and enforcement of existing laws to prevent marine litter
Promote best practices in waste management, particularly in coastal regions
Enhance opportunities to recover plastic products for recycling and energy recovery
Steward the transport and distribution of plastic resin pellets and products to its consumers and promote this practice
along the supply chain
New International Co-operation to Tackle Marine Debris
Honolulu Commitment among outcomes of Fifth International Marine Debris Conference in Hawaii
Honolulu (USA) / Nairobi, 25 March 2011 – Government
representatives, major industries and leading marine
researchers have come together to make a new set of
commitments to tackle the widespread problem of
debris in the world’s seas and oceans.
Despite decades of efforts to prevent and reduce
marine debris, such as discarded plastic, abandoned fishing nets and industrial waste, there is evidence that the problem
continues to grow. A lack of co-ordination between global and regional programmes, deficiencies in the enforcement of existing
regulations and unsustainable consumption and production patterns have aggravated the problem.
By bringing together experts from some 35 countries, governments, research bodies, corporations including the Coca-Cola
Company, and trade associations such as Plastics Europe, the Fifth International Marine Debris Conference resulted in new
commitments and partnerships to address the issue of marine debris at global, national and local levels.
A key outcome of the conference, which was co-organised by the United Nations Environment Programme (UNEP) and the
National Oceanic and Atmospheric Administration (NOAA) and held in Honolulu, Hawaii from 20 to 25 March 2011, the Honolulu
Commitment marks a new, cross-sectoral approach to help reduce the occurrence of marine debris, as well as the extensive
damage it causes to marine habitats, the global economy, biodiversity and the risks posed to human health.
The Commitment encourages sharing of technical, legal and market-based solutions to reduce marine debris, improving local and
regional understanding of the scale and impact of the problem and advocating the improvement of waste management
worldwide.
"Plastics litter in any environment is unacceptable. This global industry declaration will act as a catalyst for tangible actions at national, regional and international level. Contributing
to substantially reducing marine litter is essential for our industry.”Jacques van Rijckevorsel
Former President, PlasticsEurope
"Marine debris – trash in our oceans – is a symptom of our throw-away society and our approach to how we use our natural
resources. It affects every country and every ocean, and shows us in highly visible terms the urgency of shifting towards a low
carbon, resource efficient Green Economy as nations prepare for Rio+20 in 2012,” said United Nations Under-Secretary-General
and UNEP Executive Director Achim Steiner in a message to conference delegates. "The impact of marine debris today on flora
and fauna in the oceans is one that we must now address with greater speed,” added Mr. Steiner
"However, one community or one country acting in isolation will not be the answer. We need to address marine debris collectively
across national boundaries and with the private sector, which has a critical role to play both in reducing the kinds of wastes that
can end up in the world’s oceans, and through research into new materials. It is by bringing all these players together that we can
truly make a difference,” said Mr. Steiner.
The Commitment marks the first step in the development of a comprehensive global platform for the prevention, reduction and
management of marine debris, to be known as the Honolulu Strategy.
This document – currently being developed by conference delegates, UNEP, NOAA and international marine debris experts – will
aim to provide a strategic framework for co-ordinated action plans to prevent, reduce and manage sources of marine debris. The
Strategy will be finalised following the conference.
"This conference comes at a critical time for our world” said Monica Medina, NOAA’s Principal Deputy Undersecretary for Oceans
and Atmosphere. "The oceans and coasts are facing a multitude of stressors, including marine debris, that lead to consequences
that have both ecosystem and economic impacts. It is vitally important to bring together people committed to these issues to
share ideas, develop partnerships and move us all a step closer to the changes that are badly needed for our oceans and coasts."
Marine debris: risks to livelihoods, wildlife and human health
The impacts of marine debris are far-reaching, with serious consequences for marine habitats, biodiversity, human health and the
global economy.
At least 267 marine species worldwide are affected by entanglement in or ingestion of marine debris, including 86 percent
of all sea turtles species, 44 percent of all seabird species and 43 percent of all marine mammal species.
There is growing concern over the potential impact on human health of toxic substances released by plastic waste in the
ocean. Small particles (known as ‘microplastics’) made up of disintegrating plastic items or lost plastic pellets used by
industry, may accumulate contaminants linked to cancer, reproductive problems and other health risks. Scientists are
studying whether these contaminants can enter the food chain when microplastics are ingested by marine animals.
Accumulated debris on beaches and shorelines can have a serious economic impact on communities that are dependent
on tourism.
Marine debris may house communities of invasive species which can disrupt marine habitats and ecosystems. Heavy
items of marine debris can damage habitats such as coral reefs and affect the foraging and feeding habits of marine
animals.
Surfing for Solutions in Hawaii
One of the key themes to emerge from the Fifth International Marine Debris Conference was the need to improve global waste
management.
The Honolulu Strategy will outline several approaches for the reduction of marine debris, including prevention at land- and sea-
based sources, and the need to see waste as a resource to be managed. It will also call for public awareness campaigns on the
negative impacts of improper waste disposal on our seas and oceans – targeting street litter, illegal dumping of rubbish and
poorly-managed waste dumps.
Improving national waste management programmes not only helps reduce the volume of waste in the world’s seas and oceans
and subsequent damage to the marine environment, but can also bring real economic benefits.
In the Republic of Korea, for example, a policy of Extended Producer Responsibility has been enforced on packaging (paper, glass,
iron, aluminium and plastic) and specific products (batteries, tyres, lubricating oil) since 2003. This initiative has resulted in the
recycling of 6 million metric tonnes of waste between 2003 and 2007, increasing the country’s recycling rate by 14 percent and
creating economic benefits equivalent to US$1.6 billion.
Waste management is one of ten economic sectors highlighted in UNEP’s Green Economy Report, launched in February 2011. The
report highlights enormous opportunities for turning land-based waste – the major contributor to marine debris – into a more
economically valuable resource. The value of the waste-to-energy market, for example, which was estimated at US$20 billion in
2008 is projected to grow by 30 percent by 2014.
The scaling-up of a transition to a low carbon, more resource-efficient Green Economy is one of two key pillars of the United
Nations Sustainable Development conference to be held in Brazil next year. Also known as Rio+20, the conference aims to secure
renewed political commitment for sustainable development and address new and emerging challenges – twenty years after the
landmark Earth Summit in Rio de Janeiro.

Learning about plastics
Take a look around you! Chances are that you will find at least one thing made of plastic material. Plastics are used everywhere
these days. They help to make our lives easier, safer, more convenient, and more enjoyable. Plastics provide an environmentally
sound and cost-effective solution for many design challenges and technology breakthroughs. Think about the clothes we wear,
the houses we live in, and how we travel. Think also about our leisure pursuits, the televisions we watch, the computers we use
and the CDs we listen to. Whether we are shopping in a supermarket, having major surgery or merely brushing our teeth, plastics
are part of our lives!
Plastics in your life!
From electrical appliances, to medical equipment, packaging, automobiles and space travel, plastics are an
essential part of our lives. Why? Because plastics are versatile, lightweight, safe, durable, and cost efficient!
Versatile!
Plastics can be formed into an enormous variety of complex shapes and facilitate design solutions in thousands
of applications. They are rigid or flexible, solid or porous. Just think of the difference between a telephone, a
bottle and a plastics bag to see the sort of variety that exists.
Lightweight!
Compared with other materials plastics are very light.
This provides a number of advantages:
Less raw material consumed
Less energy in production
Easier handling/carrying
Less fuel in transport
Less air pollution in transport
Safe!
Plastics provide hygienic and protective solutions. Although they are lightweight, plastics are also extremely strong, which means
they can be used in the most demanding of situations. As they are shatterproof and can be made almost unbreakable, plastics
are widely used in areas where safety is of utmost importance - e.g. food and drink packaging and healthcare. Many of the new
safety features in modern cars rely heavily on plastics.
Durable!
Plastics provide durable and tough solutions. They do not corrode or decompose with the passage of time. Durability and weather
resistance means they are ideal for long-life applications like building and construction, keeping maintenance to a minimum - e.g.
exterior or underground cables and pipes. Plastics can absorb impact through knocks and bumps, making them ideal for the
exterior parts of lighter cars. The use of engineering plastics has become essential in many critical automotive applications.
Cost efficient!
Plastics reduce production and supply-chain costs in several ways. They reduce energy used in manufacture and enable complex
shapes to replace multi-components assemblies. High-speed form-fill-seal packaging lines increase factory throughputs and avoid
wasteful operations such as moving empty containers. Plastics' light weight reduces fuel consumption during transport.
The ABC of polyethylene
What is polyethylene?
Polyethylene is the most produced plastic in the world, with which everyone daily comes into contact. From its early days it has
been considered a real asset in the world of the materials, although at first its value was only proven as insulation of electrical
wiring. At present the power of polyethylene is its discrete reliability, its obvious solidity and its almost unlimited uses. We are so
used to this modern material, it has become something common and everyday, and we tend to take it for granted.
Polyethylene can be processed into soft and flexible as well as into tough, hard and strong products. It can be found in articles of
all kind of dimensions, from the simplest to the most complex shapes. It is used in everyday appliances, packaging, pipes and
toys. Who doesn’t daily use products like cling-foil, squeeze bottle or garbage bag? Without noticing we buy a lot of products in
the shop that are packaged in polyethylene. And when we leave the shop, our purchases are put into a carrier bag… from
polyethylene. Without realizing it, our existence has become a lot safer as a large part of our pipes; tubes and fuel tanks are
made of the solid and reliable polyethylene.
In whatever shape polyethylene is used, there is complete agreement in the excellent characteristics of this material.
Polyethylene is a good insulator, it resists caustic materials, it is almost unbreakable and is environment-friendly. Polyethylene is
reliable under every circumstance and it can easily deal with tropical temperatures as well as the frosty cold of the polar circle.
This tough material is hard wearing. Yet it is remarkably light and it can be processed into all kind of articles without any problem.
The qualities of polyethylene can be summarized into three words: it is strong, it is safe and it is versatile.
The raw material: from naphtha to polyethylene
Naphtha is extracted from crude oil. Naphtha is another word for petroleum. By strongly heating up ("crack”) the naphtha,
ethylene is released. In a factory this ethylene is transformed into polyethylene. The word polyethylene means: "a lot of ethylene
parts”. These invisible tiny ethylene parts form the building blocks for polyethylene during the production. If we could look into
the material during this process, we would see that these building blocks thread together into strings. Once these strings are
ready, they look like branches.
The raw material: where do the granules come from?
The ethylene enters the factory as a gas. When the gas is transformed into polyethylene it looks like a warm, fluid pulp. Before it
solidifies, the pulp is pushed through a plate with small holes in a constant stream. The solidifying polyethylene strings that come
out at the other end are immediately cut into small pieces by a rotating knife. The result is a mass of white, transparent granules
that look a lot like coarse hail. These granules will go to companies as raw material, where they are melted and processed into all
kinds of products.
Basic features: density and liquidity
During production polyethylene can already be given a certain characteristic. One can choose for a stiffer or for a more elastic
type. These features don’t only determine what kind of things can be manufactured from polyethylene, but also how easily it can
be done. Whether polyethylene has a stiff or elastic character depends on the "density” of the material and on the "liquidity” in its
melted form. The density and liquidity also largely depend on the amount of pressure that is applied during the production of
polyethylene. The result of a "low” or on the other hand a "high” pressure is as follows:
When producing polyethylene at low pressure it gets a high density. The invisible small substance particles form
"straight”, robust and tightly packed branches. The result is "dense” polyethylene, with a firm and stiff structure that can
be compared with a bundle of straight branches that cannot be pressed further.
Manufacturing polyethylene at high pressure on the other hand leads to a low density. The particles form a crisscross of
branches and side branches with, literally, no "line” whatsoever. The weight of this less "dense” polyethylene is lighter. It
sticks together more loosely and can be compared to a bundle of sticks of young and elastic wood with a lot of side
branches that are also branched off. When you press on such a bundle and let go of it, it bounces back into shape. So
elasticity right from the beginning.
Whether polyethylene has a liquid character or not depends on the so-called "melting index”. This technical word
indicates how slowly – or how quickly – the melted mass flows through a gap. It is not surprising that the "dense”, solid
polyethylene flows slowly and with difficulty, as it has a stiff and tough character. The "less dense” and looser
polyethylene flows much easier. When it is solidified, it feels more flexible and it is more elastic.
Three main types
By making polyethylene more or less "dense” in the factory, there is a suitable type of material available for every application. In
practice one of the following types is used in 90% of the applications.
LDPE: "low density” polyethylene
The oldest type. A soft, tough and flexible polyethylene type, used for strong, flexible consumer items, like screw caps and lids.
For a long time already, it is also used as insulation material. At present the most popular application is foil, from which carrier
bags, packaging material and agricultural plastic are made. During the high water levels in Holland in the last years, the tough
strong LDPE foil served as an improvised reinforcement for the dikes.
HDPE: "high density” polyethylene
This is the sturdiest and most inflexible type. Its sturdy and somewhat tough character can be used for a large range of
applications. For example the well-known gft-container and a number of everyday domestic products like bottles, clothes pegs
and the handle of a washing-up brush. Although HDPE is quite heavy, it can also be used for paper-thin foil that is extremely light
and feels crispy. All of us use this type of foil daily; examples are sandwich bags, pedal bin bags or packaging for vegetables, fruit
or meats.
LLDPE: a mixture of both previous-mentioned types
With this polyethylene one can go into every direction. It has some features from both of the previous-mentioned types. Both
flexible and sturdy products are made from it. LLDPE is generally used in mixtures with one of the previously mentioned
materials. Amongst others, even thinner foils can be produced. It is also used for multi-layer packaging. LLDPE is extremely tough
and inflexible. These features can be used for the production of larger items, like covers, storage bins and some types of
containers.
New developments
The development of new types of polyethylene, adapted to modern needs and made possible because of new production
techniques, clearly shows that time doesn’t stand still.
A leading hit amongst the new materials is UHMWPE. This polyethylene is really hardwearing and can resist higher
temperatures. This makes it extremely suitable for applications whereby the utmost is required from the material, like
gear wheels, gaskets, bearings, filters, cutting boards and hammers.
The latest is the so-called metallocene (metalloceen) polyethylene. This material has spectacular features because of its
very regular pattern of branches and side branches. A special type is the plastomeres (plastomeren). The distinctive
feature of this polyethylene is its extremely low density, which makes it very tough. Next to this, it is as clear as glass. In
practice, these materials are often used as reinforcement for other plastics.
Processing polyethylene into products – how is it done?
For most of the processing methods the polyethylene granules are put - via a funnel - into a cylinder where they are heated.
Inside this cylinder a rotating screw presses the melted mass through an opening at the end, after which the polyethylene can be
processed into different products, before it cools off and solidifies. The cylinder with the screw expressing the melted material is
called an extruder. The principle of the extruder can be compared to that of a sausage mill. From melted polyethylene objects in
many different models can be made, whether they are hollow of massive, large or small. Garden chairs, screw tops, doorknobs or
squeeze bottles… the most diverse shapes and dimensions are possible. During the pressing the material can also be flattened
into a sheet or stretched into foil.
The making of molded products
Injection moulds (usually called injection molding). At the end of the extruder a measured quantity of melted polyethylene
is pressed into a cooled mould. The content solidifies, the mould opens… and the ready-made product is ejected. This
method is suitable for large and small products, like tops, covers, handles, garden furniture, buckets and gft-containers.
Blow moulds. At the end of the extruder a measured quantity of polyethylene is "put through” and closed off on one side
in the shape of a tube. Through the tube opening the polyethylene is blown against the mould side, using compressed air.
It immediately solidifies and is than - ready-made – ejected from the mould. This is the designated manner to make
bottles.
Rotation moulds. This is a good method for large hollow objects, like containers or toilet booths. The polyethylene is put
into a mould as a powder. The mould rotates inside a big hot oven until the powder is melted and an even side is formed.
After cooling off the product is finished.
The making of foil
Blow foil. The melted material is pressed through the opening of the mould using compressed air and rises as a trunk of
foil. After cooling off mills flatten the foil to a double layer after which it is rolled up and ready for further processing. This
method is very suitable to make foil for bin bags and carrier bags.
Surface foil. The melted material is pressed through a very narrow opening. This results into one single layer of very thin
foil that is rolled up immediately after cooling off. This foil can, in contrast with the blow foil, only be stretched into one
direction. Surface foil is often used to stick on layers of other material.
The making of multi-layer foil
Polyethylene foil is very suitable for using in combination with layers of paper, aluminum or other plastics. It is usually used to
extra strengthen the food packaging, to be able to print on them and to ensure that the content remains fresher for a longer
period. There are three types of multi-layer foil:
Laminated foil. This is glued on aluminum, paper or other plastic as a layer. An example is the well-known coffee
packaging.
Coating. Melted polyethylene is directly pressed onto a layer of aluminum or paper. Such a coated layer is amongst others
used for photo paper and packaging for products containing oil or fat.
Coex foil. Apart from polyethylene this foil can consist of one or more layers of other plastics. In contrast with the
laminated foil, all layers of melted material are pressed together, they jointly solidify and become an indestructible foil.
An example of this multi-layer foil is cheese packaging.
The making of sheets
This is done in the same manner as with surface foil, only the opening, through which the material is pressed, is wider and in
accordance with the desired thickness of the sheet. Polyethylene sheets are often used to make relief shapes. For large, straight
pieces, for example side parts, the shapes in the sheet are made with a vacuum machine (vacuumtrekker). For smaller objects,
where each groove of the relief has to be visible, a stamp is used.
The making of foam applications for insulation
For a long time already polyethylene is a recognized insulation material, both for electricity and warmth. The foam effect is
reached by adding a foam substance or a gas to the melted polyethylene. The material will than get a cell structure that makes it
very suitable for warmth insulation. The foamed, warm mass is pressed out off the extruder via a window or tube profile, it cools
off immediately and is cut to size.
Additions
Polyethylene can sometimes be processed as it is – natural – but most of the time it will need something extra to make it more
suitable for certain applications. Substances are added to prevent objects, which are exposed to the open air, from eroding or
fading. Sometimes a substance is added that makes the foil even smoother or a substance that prevents the foils from sticking
together. Often substances are added that prevents the inflammability. Coloring substances are frequently added. In all cases it
are useful and necessary additions.
Polyethylene and the environment
Polyethylene is one of the most environment-friendly materials, since:
It is an efficient raw material. Per year, not even one percent of the total crude oil and natural gas is used for the global
production of polyethylene.
The manufacturing of polyethylene is relatively clean and efficient: the emission of harmful substances is minimal and
there is hardly any waste.
Polyethylene is extremely suitable for recycling. It is a thermoplastic material, which means that it can be melted
unlimited times and new products can be made with it. At present, many carrier bags and bin bags are made from
recycled polyethylene.
If polyethylene is collected after use and cannot be processed again, it supplies high-quality fuel for power supply.
Polyethylene: today’s and tomorrow’s material
It is beyond dispute that polyethylene is indispensable in the current world. It obtained a permanent and undisputed position on
the materials market. What other material provided so many useful innovations in the field of insulation and packaging?
The question, how to store or transport our valuable food, water and energy without loss or decay – and in the safest possible
manner –, is a lot easier to answer since polyethylene is used. It is impossible to imagine life today without polyethylene foils,
coatings and cable insulation as well as without the more extensive range of strong, light packaging and domestic applications.
Because of the superior features of polyethylene, these products cannot be realized in a better and cheaper manner using other
materials.
Tomorrow, undoubtedly, we will demand more stringent requirements from our products than we do today. Polyethylene is the
material that can endure the strictest test in the field of durability, safety, hygiene and environmental friendliness. Everything
seems to indicate that we can expect a lot more from this valuable material in the future.
