Material PC - polycarbonate
Polycarbonate is an amorphous plastic with very high impact strength, good ductility and fair stiffness. It is very difficult to break and the material is therefore considered fracture-proof (e.g. bullet-proof glass).

Light transmission is 85-90% but depends on the thickness. It has good outdoors resistance in the UV-stabilized form, but it tends to turn yellow by long exposition to sunlight. PC is transparent and can be dyed in many colours.

Environmen- tal notes Creation: Production of 1 kg of PC requires the equivalent of about 2 1/2 kg of oil (raw material and energy).

Use: Limited inflammability.

Disposal: Incineration in an incineration plant mainly producess water and carbon dioxide. Heating value is equivalent to 1/2 kg of oil.
Additional Info PC is resistant to oils, fats and alcohol also at high temperatures. Other solvents affect it, and hot water decreases its ductility.
