Halogenated Butyl Rubber

Halogenated butyl rubber (HIIR) is a chemically modified form of butyl rubber where halogen atoms, typically chlorine or bromine, are incorporated into the polymer chain. This modification enhances its properties, making it more versatile for applications that require improved air and moisture impermeability, as well as enhanced resistance to heat, chemicals, and aging. The halogenation process introduces a degree of unsaturation in the polymer, which allows halogenated butyl rubber to vulcanize more rapidly and cross-link with a broader range of curing systems compared to regular butyl rubber. The most common forms are chlorinated butyl rubber (CIIR) and brominated butyl rubber
