EPDM(Ethylene Propylene Rubber)

Characteristics
EPDM is a terpolymer of ethylene and propylene with a small amount of a third monomer (usually a diolefin) to permit vulcanization with sulfur. Generally Ethylene Propylene Rubber posses excellent resistance to ozone, sunlight and weathering, and has a very good flexibility at low temperature, good chemical resistance (many dilute acids and alkalis, polar solvents), and good electrical insulation properties.

Service Temperature
For EPDM the service temperature can be designed from -55℃ to 150℃ (for peroxide cured systems).

Hardness
40 to 90 Shore A are available.

Color
Black, brown, green, white, rust, yellow, blue, red, orange, purple and gray are available, or any assigned color from customers.

ApplicationIn
phosphate-ester based hydraulic fluids and glycol based brake fluids systems, EPDM is a good choice for sealing parts. When applied in contact with domestic water, rubber parts must pass the chloramine and chlorine resistance test. The higher saturated and amount of ethylene make EPDM better resistant to chloramine and chlorine corrosion. EPDM is also usually used in hot water or steam applications up to 150 C. Ethylene Propylene Rubber is not suitable in petroleum solvents (fuels, mineral oils, greases)
