Ethylene Propylene Diene Monomer（EPDM）

Ethylene Propylene Diene Monomer（EPDM）rubber is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. It is a kind of ethylene propylene rubber and is represented by EPDM (Ethylene Propylene Diene Monomer) . Because its main chain is a chemically stable saturated hydrocarbon.

It consists of only unsaturated double bonds in the side chain.  So it is excellent in weathering resistance,such as ozone resistance, heat resistance and weather resistance. It can be widely used in automotive parts, waterproof materials for construction, wire and cable sheathing, heat-resistant hoses and tapes. , automotive seals and other fields.

Ethylene Propylene Diene Monomer（EPDM）Performance:
Compared with other commonly used general rubber or special rubber, the main performance advantages of Ethylene Propylene Diene Monomer（EPDM） rubber are as follows:
(1) High cost performance, the raw rubber density is only 0.86~0.90kg/m3, which is the common rubber with the lightest density of raw rubber.  And it can be filled in a large amount to reduce the cost of rubber compound.
(2) Excellent aging resistance, weather resistance, ozone resistance, sunlight resistance, heat resistance, water resistance, water vapor resistance, UV resistance, radiation resistance and other aging properties, and other unsaturated diene rubber such as NR, SBR, When BR, NBR, and CR are used together, ethylene propylene diene monomer（EPDM）can function as a polymeric antioxidant or an antioxidant.
(3) Excellent chemical resistance, acid, alkali, detergent, animal and vegetable oil, alcohol, ketone, etc.; outstanding water resistance, superheat resistance, water vapor resistance; resistance to polar oil.
(4) Excellent insulation performance, volume resistivity 1016Q•cm, breakdown voltage 30～40MV/m, dielectric constant (1kHz, 20°C) 2.27.
(5) The applicable temperature range is wide, and the minimum use temperature is -40 to -60 °C, which can be used at 130 °C for a long time.
