Chlorinated Butyl Rubber
Chlorinated Butyl Rubber
Chloro butyl rubber CIIR is a copolymer rubber of chloro isobutylene and isoprene. It has many of the attributes of synthetic butyl rubber, including low gas and moisture permeability, good vibration damping, low glass transition temperature, excellent resistance to ageing and weathering. Compared to butyl rubber, the chlorinated sites are more reactive, providing faster cure with lower amount of curatives and better adhesion to unsaturated rubbers and metals.

Features of Chlorinated Butyl Rubber
Improved heat resistance: Chlorinated butyl rubber has better heat resistance compared to regular butyl rubber, making it suitable for applications that involve high-temperature exposure.
Enhanced chemical resistance: The chlorination process enhances the rubber's resistance to chemicals, oils, and solvents, expanding its usability in various industrial settings.
Better adhesion: Chlorinated butyl rubber exhibits improved adhesion properties, allowing it to bond more effectively with other materials, such as fabrics or metals.
Reduced gas permeability: Chlorinated butyl rubber has lower gas permeability, making it suitable for applications where gas or moisture barrier properties are essential, such as in the production of inner tubes, air bladders, or liners for storage containers.
Good weather resistance: The chlorination process improves the rubber's resistance to weathering, UV rays, and ozone, which extends its lifespan and durability.
Application of Chlorinated Butyl Rubber
Chloro butyl rubberCIIR has superior air impermeability, outstanding performance of heat-resistance, chemical corrosion-resistance, thermal aging resistance, and good curing performance. It can be widely used for tire inner liners, medical stoppers, corrosion-resistance lining, protective clothing, shoes production and TPV industry.
