The development space of the chlorosulfonated polyethylene (CSM) industry continues to expand, and local companies have competitive advantages in the global market

Chlorosulfonated polyethylene (CSM), also known as hyperon, refers to a white or yellow elastomer made from low-density polyethylene or high-density polyethylene through chlorination and chlorosulfonation reactions. Chlorosulfonated polyethylene is soluble in chlorinated hydrocarbons and aromatic hydrocarbons. It has aging resistance, corrosion resistance, wear resistance, flame resistance and other properties. It is widely used in automobile manufacturing, wires and cables, waterproof membranes, waterproof coatings and other fields. According to different Mooney viscosity, chlorosulfonated polyethylene can be divided into two types: low Mooney viscosity type and high Mooney viscosity type.

The preparation methods of chlorosulfonated polyethylene include gas-solid method and solvent method. The gas-solid method refers to using chlorinated polyethylene as the main raw material, passing in reaction gases such as sulfur dioxide and chlorine under ultraviolet irradiation, and finally producing chlorosulfonated polyethylene. This method is green and environmentally friendly, has a short production process, and has high raw material utilization rate. Advantages, it is expected to become the mainstream preparation method of chlorosulfonated polyethylene in the future; the solvent method is the traditional preparation method of chlorosulfonated polyethylene. This method uses carbon tetrachloride as raw material, and is easy to cause environmental pollution when used in large quantities. In the future, it will gradually be replaced by gas-solidified polyethylene. replaced by law.

Chlorosulfonated polyethylene is mainly used in automobile manufacturing, wires and cables, waterproof membranes, waterproof coatings and other fields. In the field of automobile manufacturing, chlorosulfonated polyethylene can be used to produce radial tire inner liner glue, oil-resistant hoses, etc.; in the field of wires and cables, chlorosulfonated polyethylene has electrical insulation resistance and can be used as cable sheathing materials; in waterproofing In the field of membrane materials, chlorosulfonated polyethylene waterproof membrane has the advantages of good waterproofing and weather resistance, and is widely used in construction projects. Benefiting from the growth in market demand, the development space of the chlorosulfonated polyethylene industry continues to expand. According to the “2023-2028 China Chlorosulfonated Polyethylene (CSM) Industry Market In-depth Research and Development Prospects Forecast Report span>” shows that my country’s chlorosulfonated polyethylene market size will reach 410 million yuan in 2022.

The global chlorosulfonated polyethylene industry is highly concentrated, with leading companies occupying a major share of the market. Japan’s Tosoh Co., Ltd. (TOSOH), Japan’s Toray Co., Ltd. (Toray), Japan’s TDK Co., Ltd., the U.S. DuPont (DuPont), South Korea’s LG Chem, etc. are world-renowned suppliers of chlorosulfonated polyethylene. . In terms of the local market, my country is one of the major producers of chlorosulfonated polyethylene in the world. Local companies have competitive advantages in the global market. Ruihe New Materials, Hongrun Chemical, Jilin Petrochemical, Polysheng Chemical, etc. are the leading producers of chlorosulfonated polyethylene in my country. major producers.

Industry analysts said that chlorosulfonated polyethylene, as an emerging elastomer material, is widely used in many fields, and with market demand Gradually released, the development trend of the industry will continue to improve. my country is one of the world’s major producers of chlorosulfonated polyethylene. As the level of technological innovation of local enterprises continues to improve, the development speed of my country’s chlorosulfonated polyethylene industry will further accelerate.
