General introduction

Chlorosulfonated polyethylene, referred to as CSM, is a kind of elastomer which has completely saturated main chain and pendant group and can be vulcanized by all kind of cross linking agent. Because of its unique molecular structure, CSM vulcanizate has excellent ozone resistance and weatherability. In additional, properly formulated CSM vulcanizate has excellent resistance to heat, oil, chemicals and aging. 

SUNPREN™ CSM is chlorosulfonated polyethylene produced by Sundow Polymers Co.,LTD.

Characteristic of CSM

 Permanent bright colors

 Superior ozone and weather resistance, even for the formation without carbon black

 High working temperature up to 150℃

 Resistance to a wide range of aggressive chemicals

 Moderate resistance to oil and solvent depending on chlorine level

 Good flame retardancy

 Electrical insulating properties

 Excellent resistance to abrasion and mechanic abuse


SUNPREN CSM 


Sundow Polymers supplies two series CSM grades, one is H-series, which is produced by traditional solvent technology; another is M-series, which is produced by non-solvent technology.
