Chlorosulfonated Polyethylene (CSM) : An industry solution for high-performance elastomers

Chlorosulfonated Polyethylene (CSM) is an important synthetic rubber produced by chlorination and chlorosulfonation reactions of the main chain of polyethylene (PE). CSM features outstanding ozone resistance, weather resistance, chemical corrosion resistance, good heat resistance, flame retardancy, as well as certain oil resistance and mechanical properties, making it one of the preferred elastomer materials in high-performance seals, rubber hoses, cable sheaths, industrial linings (such as storage tanks and pipes), and roof waterproofing membranes.

CSM has many outstanding features, such as strong tolerance to various chemical substances and is suitable for chemical processing plants. It has excellent weather resistance and ozone resistance, and is widely used outdoors. It also has good heat resistance and can be used in the manufacturing of wire and cable coatings. CSM has moderate oil and solvent resistance and excellent mechanical properties, making it suitable for the automotive and mechanical industries.

In the automotive field, CSM plays a crucial role and is used to produce various components, such as gaskets, sealing rings and hoses.For example, gaskets and rings made from CSM provide a reliable and durable barrier against fluid and gas leakage in engines and other critical systems.

Its heat resistance, electrical insulation and flame retardant properties make it an ideal material to ensure the safe and efficient transmission of electricity, including the wiring of power cables and electronic devices. In addition, CSM is used to manufacture pipes, storage tanks and linings that come into contact with a variety of corrosive chemicals. These can resist the corrosion of chemicals and ensure the production process.
