CSM Soft Seated Butterfly Valve Spare Parts Rubber Seat Oil And Heat Resistance
Oil and heat resistance CSM Soft Seated Butterfly Valve Rubber Seat
Chlorosulfonated polyethylene, short called as CSM.
1.1 Excellent resistance to ozone, weather, chemical resistance and discoloration.
1.2 Good heat resistance, continuous use temperature 120-140 °C, intermittent use temperature up to 140-160 °C.
1.3 Because it contains more chlorine, it has flame resistance and burns very slowly. When it is removed, it will extinguish itself.
1.4 Good oil and heat resistance, comparable to acrylonitrile 40-containing nitrile rubber, but not aromatic.
1.5 Vulcanizate has excellent dielectric properties.
1.6 Low temperature resistance.
Scope of application: Mainly used for industrial products, wire and cable sheathing, hoses, equipment lining, coatings, construction such as waterproof coating, rubber flooring, pool lining, etc. and automotive parts.
