Custom EPDM O Ring Food Grade Excellent Ozone / Chemical Resistance
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
Trade Names:
ASTM D1418 Designation: EPDM
ASTM D2000/SAE J200 Type, Class: AA, BA, CA, DA
Apple Compound Designation: EP
Standard Color: Black
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.
