Chlorosulphonated Polyethylene (CSM)
Chlorosulphonated polyethylene or chlorosulfonated polyethylene (CSM) is a kind of white or light color elastomer which is charactered by its own unique properties as well as the same characteristics as the raw rubber. In aromatic and chlorine hydrocarbons, it can be soluble, but in ketones and ether, it can be only swelling, not soluble.
Product & engineering
Understand the product.
Chlorosulphonated polyethylene or chlorosulfonated polyethylene (CSM) is a kind of white or light color elastomer which is charactered by its own unique properties as well as the same characteristics as the raw rubber. In aromatic and chlorine hydrocarbons, it can be soluble, but in ketones and ether, it can be only swelling, not soluble.
The chemical structure bond of CSM is completely saturated, so the vulcanizate has excellent properties, such as ozone resistance, weather and aging resistance, chemiacal resistance, ionizing radiation resistance, colorability, good physical and mechanical properties, thermal aging resistance, heat and low temperature resistance, flame retardancy, abrasion resistanceand wonderful electric insulation, etc.
