Propylene Rubber (EPM, EPDM) / 三元乙丙橡膠
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.
For EPDM the service temperature can be designed from
-55 C to 125 C or up to 150 C (for peroxide cured
40 to 90 Shore A are available.
Black, brown, green, white, rust, yellow, blue, red,
orange, purple and gray are available, or any color
we can design for you.
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.
Rubber is not suitable in petroleum fluids (fuels,
mineral oils, greases)
