Global Chlorosulphonated Polyethylene (CSM) Market Growth 2025-2031
Description
The global Chlorosulphonated Polyethylene (CSM) market size is predicted to grow from US$ 68.9 million in 2025 to US$ 121 million in 2031; it is expected to grow at a CAGR of 9.8% from 2025 to 2031.
The impact of the latest U.S. tariff measures and the corresponding policy responses from countries worldwide on market competitiveness, regional economic performance, and supply chain configurations will be comprehensively evaluated in this report.
Chlorosulfonated polyethylene (CSM) is an important specialty synthetic rubber made from high-density polyethylene (HDPE) or low-density polyethylene (LDPE) in solution through a two-step chemical reaction of chlorination and chlorosulfonation. Its molecular structure is characterized by the replacement of some hydrogen atoms on the polyethylene backbone with chlorine atoms, and the introduction of a small amount of chlorosulfonyl groups. Its core performance advantage lies in its excellent weather resistance, ozone resistance and chemical corrosion resistance. CSM has extremely strong resistance to erosion by sunlight (especially ultraviolet rays), oxygen and ozone, which is far superior to many general-purpose rubbers, making it an ideal material for long-term outdoor use, such as wire and cable sheathing and roof waterproofing membranes.
Global Chlorosulphonated Polyethylene (CSM) key players include Tosoh, Jilin Petrochemical and Jiangxi Hongrun Chemical Industry, etc. In 2024, the global three largest players hold a share approximately 80% 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 is the largest segment, with a share over 52%. And in terms of application, the largest application is Automotive, has a share over 36%, followed by Construction, Industrial Products and Wire & Cable, etc.
The chlorosulfonated polyethylene market can be divided into high-performance products and standard-grade products. High-performance CSM mainly meets the needs of automotive, construction and industrial fields for excellent durability and endurance, while standard-grade CSM is suitable for applications with medium performance requirements and is popular for its cost-effectiveness. The automotive industry is an important contributor to the chlorosulfonated polyethylene market, and CSM is used to manufacture air conditioning hoses, hydraulic hoses, fuel hoses, as well as gaskets, seals, etc. The construction field is also a key application scenario, and CSM is used for roof membranes, waterproofing solutions and sealing applications. Environmental protection and sustainable development are important directions, and the industry is shifting towards bio-based alternatives and environmentally friendly formulations.
