CSM 40 rubber is a kind of white grey material , tasteless evenly rubber-shape, and it has the mutual character with rubber which also has its own property.

The chemical structure of Chlorosulfonated Polyethylene is a fully saturated backbone. CSM Rubber has excellent ozone resistance, atmospheric aging resistance chemical resistance, ionizing radiation resistance and color stability, good mechanical properties, thermal aging resistance, low temperature resistance, flame resistance, abrasion resistance and electrical insulation function.

Chlorosulfonated Polyethylene is a kind of white or yellowish elastomer in round chip with not only the same properties as base polymer but also special properties of itself. It’s soluble in aromatic hydrocarbon and hydrochloric ether, insoluble in fatty hydrocarbon and alcohol, only swells but not be soluble in ketone and ether. It has excellent ozone resistance, atmospheric ageing resistance, chemical resistance, etc., also has better physical mechanical features, heat ageing resistance, heat endurance, subzero resistance, fuel resistance, abrasion resistance and electrical insulation.
