Colors may be selected maximize or minimize heat retention and additives can be formulated to help film resist the degrading effects of sunlight, heat, moisture and agricultural chemicals. Greenhouse film must remain strong and flexible, even after months or years of exposure to intense sunlight, heat and humidity. These include colors that help control light transmission and heat retention.

With better heat and crush resistance versus foamed PE and FEP, Maxxam SY formulations also include options for 'zero halogen, low smoke and fume.' Crush and heat resistance Discover two distinct advantages over regular polyethylene: greatly-improved heat resistance and oil resistance

PolyOne supported the design and production engineers at Sylumis with thermal simulation and mold filling analysis to help the manufacturer optimize the geometry, heat transfer and manufacturability of the heat sinks. The Therma-Tech conductive formulation selected for these LED lamps outperforms aluminum, the material traditionally used in heat sinks, with a 25% increase in heat exchange surface area and a 9% reduction in weight.

High heat and chemical resistance Heat Sink Material for LED Therma-Tech™ provides thermal and electrical conductivity for high powered LED heat sink
