Ethylene Propylene Rubber (EPM, EPDM)

Ethylene Propylene Rubber (EPM, EPDM) / 三元乙丙橡膠

EPM is a Copolymer of ethylene and propylene. 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 hasa 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 C to 125 C or up to 150 C (for peroxide cured system
s).

Hardness

40 to 90 Shore A are availa
ble.

Color

Black, brown, green, white, rust, yellow, blue, red, orange, purple and gray are available, or any color we can design for y
ou.

Application

In phosphate-ester based hydraulic fluids and glycol based brake fluids systems Ethylene Propylene Rubber is good choice for sealing parts. EPDM is also is usually used in hot water or steam applications up to 150
C.

Ethylene
Propylene Rubber is not suitable in petroleum fluids (fuels, mineral oils, greases)
