Chlorosulfonated Polyethylene (CSM)


General introduction1555312778330862.jpg

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.

SUNPREN™ CSM has excellent mechanical property and good solubility in some organic solvents, so not only it can be used for general rubber applications, some grades can also be used for applications such as coating, adhesives.
