Global Chlorosulfonated Polyethylene (CSM) Supply, Demand and Key Producers, 2026-2032

The global Chlorosulfonated Polyethylene (CSM) market size is expected to reach $ 129 million by 2032, rising at a market growth of 9.3% CAGR during the forecast period (2026-2032).

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.

Global Chlorosulfonated Polyethylene key players include Tosoh, Jilin Petrochemical and Jiangxi Hongrun Chemical Industry, etc. In 2024, the global three largest players hold a share approximately 85% in terms of revenue.

The largest market is China, has a share about 50%, followed by Japan, with around 40% market share respectively.

In terms of product, Low Mooney Viscosity (Below 60) is the largest segment, with a share over 50%. And in terms of application, the largest application is Automotive, has a share over 35%, followed by Construction, Industrial Products and Wire & Cable, etc.

The automotive industry is the core application of CSM, including hoses, sealing strips, etc. With the rise of electric vehicles, the demand for lightweight and temperature-resistant materials has increased; in addition, the construction industry has also promoted the expansion of CSM applications in areas such as roof waterproofing and sealing membranes. On the technical level, the industry is accelerating the development of new formulas and green processes to improve sustainability and material performance, while responding to fluctuations in raw material costs and challenges in environmental regulations.
