In Mid-Q4 2025, the APAC Chlorosulphonated Polyethylene Rubber price surged during Oct-Nov. This rise was supported by strong demand and tight supply conditions, as well as increasing energy and transportation costs. Building works in China, India, and ASEAN countries continue to support Chlorosulphonated Polyethylene Rubber demand for membranes and roofing, water repellents, sealants, and clear coating. There was also strong Chlorosulphonated Polyethylene Rubber demand from the automotive industry, driven particularly by the booming vehicle production in India and Southeast Asia. The growth in electric vehicles pushed even higher demand for hoses, gaskets, and protective parts. Industrial use, such as cable sheathing and special coatings, is to a large extent responsible for the demand for Chlorosulphonated Polyethylene Rubber. With steady feedstock access, output was unhindered, and Chinese exports led the way. A balanced Chlorosulphonated Polyethylene Rubber market is expected in the foreseeable future, and prices are anticipated to hold steady as seasonal and holiday factors prevail in supply and demand.
