Ethylene Propylene Rubber (EPM, EPDM)
EPM is a Copolymer of ethylene and propylene, EPDM is 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 have very good flexibility at low temperature, good chemical resistance (many dilute acids and alkalis, polar solvents), and good electrical insulation property.

SERVIEC TEMPERATURE
For EPDM the service temperature can be designed from -55℃ to 125℃ or up 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 color we can design for you.

APPLICATION
In phosphate-ester based hydraulic fluids and glycol based brake fluids systems Ethylene Propylene Rubber is good choice for sealing parts. Appling in domestic water, rubber parts must pass the chloramine and chlorine resistance test. It is not suitable for any types Ethylene Propylene Rubber, higher saturated EPDM or EPM and higher ethylene content will be well for chloramine and chlorine attacking. It also usually be used in hot water or steam up to 150℃.
Ethylene Propylene Rubber is not suitable in petroleum fluid (fuels, mineral oils, greases)
