Description
An elastomeric terpolymer composed of ethylene, propylene and a small amount of a diene. Ethylene-propylene diene terpolymer, or EPDM, is an off-white, rubber-like material that can be vulcanized with sulfur, peroxides or phenolics 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.
Synonyms and Related Terms

Physical and Chemical Properties
The ratio of the polymeric components can be varied to provide products with different characteristics. Some products contain additives such as fillers and plasticizers.
EPDM is affected by hydrocarbon and halogenated solvents. It is insoluble in water, acids, alkalis and ketones (acetone).
