ethylene-propylene rubber

polymer

Ethylene-propylene rubber (EPR) is a synthetic elastomer copolymer composed of ethylene and propylene monomers, valued for its excellent resistance to heat, ozone, and weathering. It is widely used in automotive seals, gaskets, and hoses, as well as in roofing membranes, cable insulation, and industrial vibration damping applications, where its low-temperature flexibility and chemical resistance make it preferable to natural rubber or neoprene in outdoor and thermally demanding environments.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
