Description: A copolymer of ethylene and propylene (EPR), combined with a third comonomer adiene(EPDM), Ethylene Propylene has gained wide seal industry acceptance for its excellent ozone and chemical resistance characteristics.

Key Use(s): Outdoor weather resistant uses. Automotive brake systems. Automobile cooling systems. Water applications. Low torque drive belts.

Temperature Range
Standard Compound: -40° to +275°F
Special Compound: -67° to +302°F

Hardness (Shore A): 40 to 95

Features: When compounded using peroxide curing agents high temperature service can reach +350°F.  Good resistance to acids and solvents (i.e. MEK and Acetone).

Limitations: Have no resistance to hydrocarbon fluids.

EPDM has outstanding resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight (-40ºF to +275ºF); but it is not recommended for gasoline, petroleum oil and grease, and hydrocarbon environments. This popular rubber compound is usually the first choice for low torque drive belt applications.
