Chlorosulphonated polyethylene CSM - General grade
Chlorosulphonated polyethylene (CSM)
These materials give good service in many media including water, dilute alkalis, lower alcohols, aliphatic hydrocarbons, silicone oils and greases, vegetable oils, and mineral-based and water/glycol hydraulic fluids.
They also show excellent resistance to weathering.
Typical operating temperatures
-30°C to +120°C continuous, or +150°C intermittent.
Fluid sealing duties
Used mainly for static sealing duties. They are not recommended for dynamic applications as compression set resistance is limited.
