IMPACT ProTeCTIonDamage to greenhouse glazing can be hazardous and expensive. Marlon polycarbonate is 200 times more resistant to impact than glass, providing excellent protection against hailstones, vandalism and accidental damage.
wInD ProTeCTIonMarlon polycarbonate sheet has a very high stiffness to weight ratio providing a lighter glazing alternative ideal for greenhouse structures.
FIre ProTeCTIonMarlon polycarbonate sheets comply with most international fire resistance standards.
ConDensATIon ProTeCTIonThe optional anti-drip surface layer prevents the formation of water droplets and reduces condensation and associated fogging. This technology positively impacts crop yields byimproving photosynthetic light transmission and decreasing the spoilage caused by dripping.
UV ProTeCTIonThe co-extruded UV absorption layer acts to block the damaging UV radiation which burns plants, flowers and people whilst transmitting the natural solar light for photosynthesis, encouraging healthy crop development. The structured options are both insulating and light diffusing.
PLASTICS FOR HORTICULTUREINTRODUCTION

Manufactured by plastics specialists Brett Martin, Marlon is a technically superior product which not only achieves the high levels of photosynthetic light transmission necessary for healthy plant growth but also combines high impact resistance, condensation control and UV protection.

PLASTICS FOR HORTICULTURECORRUGATED POLYCARBONATE
Marlon Cs longlife is available in Diffuser opal, a soft opal tinted sheet with advanced solar control and enhanced UV resilience. Diffuser opal’s clever technology dissipates daylight as it travels through the sheet creating a much softer, diffused light inside the building minimising shadows and eliminating hotspots with can be damaging to crops. enhanced UV resilience reduces yellowing caused by prolonged exposure to direct sunlight allowing the sheet to maintain it light transmission properties for longer and prolonging the life of the sheet.

PLASTICS FOR HORTICULTUREPROPERTIES
CHEMICAL RESISTANCEMarlon polycarbonate has, in general, excellent resistance to most chemicals; resistance to specific compounds depends on concentration and temperature, duration of exposure and stress within the sheet. Contact with plastic coated metal sheets, wet wood preservatives, solvents and alkali cleaners should be avoided.
IMPACT RESISTANCEPolycarbonate exhibits greater resistance to impact than any other glazing material over a temperature range of -40 to +130°C. It is up to 200 times more resistant to impact than glass. high impact resistance means that Marlon polycarbonate is suitable for use in areas with a high risk of glazing breakage, such as areas prone to vandalism or hail storms, where other glazing materials might be inappropriate.
FALLING DART The impact test illustrated demonstrates the impact resistance of Marlon polycarbonate sheet. A striker of diameter 16mm contacts a sample of sheet placed on a support ring with inner diameter 38mm. A weight of 1.8kg is dropped on to the striker from a height of 1.5m. The resulting impact energy of 27nm only dents the sample: it does not crack or penetrate.
