Ethylene propylene terpolymer

Jump to: navigation, search


An elastomeric terpolymer composed of ethylene, propylene and a small amount of a diene. Ethylene-propylene terpolymer, or EPDM, is an off-white, rubber-like material that can be vulcanized with sulfur to form a chemically resistant rubber. It is resistant to ozone, acids and alkalis and retains its elasticity over a wide temperature range (-51 to 148C). EPDM is used for gaskets, coated fabrics, footwear and for automobile and appliance parts. See also ethylene propylene rubber.
