Hypalon is a chlorine containing special elastomer with high saturated chemical structure, which is prepared by chlorination and Reed reaction of polyethylene. The average molecular weight of CSM2910 is 30,000, CSM4010 is 40,000, CSM3304 is 120000, C and SM2305 is 100000. It appears as white or milky flake or granular solid with relative density 1.07 ~ 1.28. Mooney viscosity 30 ~ 90. Brittle temperature-56 ~-40 °C. Soluble in aromatic hydrocarbons and chlorinated hydrocarbons, insoluble in fats and alcohols, in ketones and ethers can only be swelling can not be dissolved. Because the molecular structure is completely saturated, it has excellent properties such as resistance to chemical medium corrosion, resistance to ozone oxidation, resistance to oil corrosion and flame retardant, it is a kind of high-performance special rubber, which is resistant to climate change, heat, ion radiation, low temperature, abrasion and electric insulation

As a special rubber, CSM has been widely used in the fields of special pipe, transport belt, seal, wire and cable, waterproof coil, automobile industry, etc. . For example, the laminated pipe made with CSM as the inner layer has low permeability to fluorohydrocarbon refrigerant, so it is suitable for refrigerant delivery pipe. The mechanical properties and thermal properties of vulcanizates were improved by blending SM with fluororubber and EPDM. Blending EVA polymer with CSM and isoprene rubber can make composite materials with slip resistance, wear resistance and oil resistance. The vulcanized rubber with high oil resistance and ozone resistance can be made by mixing CSM with PVC and PU in extruder.
