Product Details

Commodity Name:Chlorosulfonated Polyethylene (CSM)

CAS No.：68037-39-8

Polygrand adopts newly developed production process ,which is safe and friendly to the environment.

Product Characteristics:
Chlorosulfonated polyethylene (CSM) is a special synthetic rubber prepared by chlorination and sulfonation of polyethylene at the same time. It has a fully saturated main chain and side group, and can be vulcanized by metal oxide, sulfur, polyol, peroxide and other vulcanization systems. It is suitable for vulcanization by various vulcanization molding methods. Because of this structure, CSM has many characteristics in the rubber industry, including:
1. Excellent ozone resistance and weather resistance;
2. Good resilience;
3. Corrosion resistance to many chemicals;
4. Moderate oil and solvent resistance;
5. Good flame resistance;
6. Excellent friction resistance and mechanical damage resistance.

Product Applications

1. Automobile parts
CSM can be used in automotive air conditioning hoses, hydraulic hoses, exhaust hoses, fuel hoses, automotive steering power pipes, vacuum hose, spark plug caps and ignition wires, etc.
2. Wires & cables
CSM has excellent wear resistance, heat resistance, low water absorption, sun resistance, ozone resistance, corona resistance, etc., which can be used for the sheath of wires and cables; it has good color stability under high temperature conditions and UV resistance , which can be used to make the outer sheath of color cables. The cables with CSM sheath can meet the requirements of IEEE standard and has been used in nuclear power plants.
3. Hoses
CSM has excellent chemical resistance and low permeability to water and fluorinated cold aging agent. It is often designated as all kinds of air conditioning hose materials, liquefied petroleum gas hoses, chemical resistant hoses, etc.
4. Waterproof tapes
CSM has the characteristics of natural vulcanization and anti microbial growth. It is often made into reinforced waterproofing tapes, which is used for bridge cables, reservoir water storage, river levee, roof waterproofing, etc. At the same time, it has good chemical resistance, which makes it more widely used in the water treatment tank of chemical industry.
5. Construction
CSM is used for caulking agents, surface layer of PU foam, insulation materials, foam products, heat insulation tapes, etc. The heat insulation tapes made of CSM has excellent waterproof, heat insulation and anti ultraviolet characteristics. It maintains thermal plasticity in the process of roof construction, and can be bonded together by heating to make it overlap with each other.
