Ethylene Propylene Rubber – EPDM / EPR

Do to its low level of unsaturation in the terpolymer grades (fully saturated in copolymer grades) it has excellent resistance to oxygen, ozone and general weatherability. Also, as this is a “non-polar” material, it has very good resistance to non-hydrocarbon fluids including alcohols, glycols (coolant), Ketones and phosphate esters (brake fluids) and can be found in automotive hoses, wire and cable and even oil patch application for Geo-thermal packers.

Excellent Weatherability
Excellent low temperature properties -67°F/-55°C
Good high temperature resistance up to 302°F/150°C (peroxide cured)
