Contáctanos Formato PDFn 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.
n 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
n 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.
