PRODUCT DESCRIPTION

Chlorosulfonated polyethylene material 

Chlorosulfonated polyethylene as CSM, is a vulcanized elastomer, having a completely saturated main chain and side groups ,and various of vulcanization methods can be used. Because of this structure, CSM vulcanizate has excellent property in ozone resistance, oxidation resistance and aging resistance. In addition, if suitably formulated, CSM vulcanizates will have excellent heat resistance, oil resistance, chemical resistance, and aging resistance.

Characteristics

 

1) Excellent resistance to ozone and weather resistance, even without the carbon black products having these properties;

2) Resistance to high temperature of 145 degrees;

3) Tolerated to many chemical corrosions;

4) By the influence of the chlorine content, and it has a moderate oil resistance and solvent resistance;

5) Good flame retardant properties (associated with chlorine-containing polymers);

6) Excellent abrasion resistance and mechanical damage.
