Chlorosulfonated Polyethylene (CSM)


    General introductionCSM.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.

    Characteristic of CSM

    image.png Permanent bright colors

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

    image.png High working temperature up to 150℃

    image.png Resistance to a wide range of aggressive chemicals

    image.png Moderate resistance to oil and solvent depending on chlorine level

    image.png Good flame retardancy

    image.png Electrical insulating properties

    image.png Excellent resistance to abrasion and mechanic abuse


    SUNPREN CSM 

    Sunpren™ CSM is produced by new non-solvent technology (Gas-Solid phase technology) which is called M series.Its production process is without solvents such as carbon tetrachloride, so it is environmental friendly and doesn’t destroy the ozone layer. So itdoesn’t contain harmful organic solvent and it’s not harmful to operator’s health. Its mechanical property is similar to CSM which is produced by traditional solvent technology; and it can meet the technical demand of most general rubber applications. Another important point, as this technology is environmental friendly, it is easier to be approved for capacity expansion.
