Ethylene Propylene Diene Monomer (EPDM)

EPDM elastomers provide excellent resistance to heat, water, steam, ozone and UV light (color stability) while providing very good low temperature flexibility properties. These compounds also withstand the affects of brake fluids, alkali, mild acidic and oxygenated solvent environments. EPDM compounds are not recommended for gasoline, petroleum oil and greases, and hydrocarbon solvent environments.

EPDM’s are very effective for outdoor functions requiring long term weathering properties. EPDM elastomers are also suitable for use in hot water and steam environments. EPDM’s are especially suited to high temperature brake fluid applications.
