EDPM Products

EPDM (ethylene propylene diene monomer) provides superior properties for outdoor and high temperature applications. EPDM has excellent resistance to heat, ozone and sunlight and good resistance to alkalis, acids and oxygenated solvents. Very good temperature flexibility, superior resistance to water and steam. It is highly extendible and is sulfur and peroxide curable.

Our EPDM Products are available in Premium, Commercial & Spec Grades or as a specialty product.
