Description
An elastomeric copolymer of ethylene and propylene. Ethylene-propylene, or EPR, is a rubber-like material that can be crosslinked 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. See also Ethylene propylene terpolymer (EPDM).
Synonyms and Related Terms
ethylene-propylene rubber; EPR; EPM; goma de etileno- propileno (Esp.);
Other Properties
Soluble in most organic solvents. Resistant to mineral acids and alkalis.
Hazards and Safety
Combustible.
