MCSM is a modified chlorosulfonated polyethylene rubber, its air tightness is equivalent to halogenated butyl rubber, oil resistance is better than nitrile rubber, and has excellent aging resistance and high temperature resistance, and various types of rubber Olefin rubber has excellent compatibility. Mainly used for tire sealing layer and rubber products such as oil resistance, high temperature resistance and weather resistance. When used in tire sealing layer, it can be substituted for bromobutyl rubber. Due to its slow curing speed, it is generally recommended to replace 5-10 parts. The combined use of modified chlorosulfonated polyethylene rubber can significantly improve the processing performance of the rubber material and increase the air tightness of the rubber material.
