Various processing techniques
Hand Lamination
• Reinforcing
glass is wetted and
de-areated manually
• Typical procedure for
small or complex forms
• Small scale production
• Connect pipes and
create fittings
• Linings: renovation of
existing structures Inspection chamber, Source: Flowtite
Spray header bank for slurry, Source: Selip SPA
8
Various processing techniques
Centrifugally Casting
• Resin, glass and filler
are inserted by a steel
arm (feeder) into a
rotating mould
• Ashland resins
provide e.g. flexible
and smooth inner
liner for sewage and
water transport
applications

Various processing techniques
Filament Winding
• Raw material applied
to rotating mandrel
• Continuous and
discontinuous
• Oriented fiber
reinforcement:
circumferential,
helically, cut or
sprayed fiber
• On site winding
for large diameter
• Ashland offering tailor
made solutions for
your process and
needs.

Ashland: Latest development
PET Resin
• Developments in resin chemistry have historically
enable the production of composite parts which are
stronger, lighter and have lower overall unit costs
• Environment, cost and properties are key elements to
be considered for the production of unsaturated
polyester resins synthesized from the glycolisys of
PET.
• Ashland has dedicated considerable amount of
research to develop a family of UPR resins containing
post-consumer and/or post-industrial PET which is
already available for a number of applications
