Ethylene Propylene (EPDM)
EPDM rubber is used in seals (for example, it is used in cold-room doors since it is an insulator, as well as in the face seals of industrial respirators in automotive paint spray environments, where silicone must be avoided). EPDM is also used in glass-run channels, radiators, garden and appliance hose, tubing, pond liners, washers, belts,electrical insulation, vibrators, O-rings, solar panel heat collectors, and speaker cone surrounds.
The most common use, however, is probably in vehicles. It is used in door seals, window seals, trunk seals, and sometimes hood seals. Frequently, these seals are the source of noise due to movement of the door against the car body and the resulting friction between the EPDM rubber and the mating surface (painted sheet metal or glass).Rubber temperature restistance chart (in °C) Available qualities
