Royalene® EPDM Elastomers

Royalene® EPDM elastomers are terpolymers of ethylene and propylene, and a non-conjugated diene. The main attributes of EPDM are its electrical properties and outstanding resistance to oxidation, ozone, and the effects of weathering. Royalene® EPDM Elastomers are highly extendable, allowing high levels of fillers and plasticizers to be added while maintaining good physical properties.

Common applications include automotive weather seals, hoses, tire sidewalls, single-ply roof membranes, and wire and cable insulation.
