Ethylene propylene rubber

Jump to navigation Jump to search


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.
