Description
An elastomeric copolymer of ethylene and propylene. Ethylene-propylene rubber, or EPR, is a rubber-like material that can be cross-linked with peroxides. It is more expensive than EPDM but has better compression set. Ethylene propylene rubber is resistant to ozone, acids and alkalis and retains its elasticity over a wide temperature range
(-51 to 148C). EPR is used for gaskets, coated fabrics, footwear and for automobile and appliance parts.
Synonyms and Related Terms
ethylene-propylene rubber; EPR; EPM; goma de etileno- propileno (Esp.);
Risks
Combustible.
Other Properties
Soluble in most organic solvents. Resistant to mineral acids and alkalis.
