Halobutyl Rubber

Butyl rubber is an elastomeric copolymer of isobutylene and of isoprene, offered in a range of polymer compositions. Halogenated butyl rubber greatly extended the usefulness of butyl rubber by providing much higher curing rates and enabling co-vulcanization with general purpose rubbers such as natural rubber and styrene-butadiene rubber (SBR).

Halogenation of butyl rubber with bromine produces rubber which is particularly suitable for the tire industry, wherever low permeability to gases and liquids is required, e.g., tire inner liners, hoses, seals and membranes. It is also suitable for pharmaceutical stoppers and rubber articles needing good resistance to chemicals, weathering, and ozone, such as tank linings, conveyor belts, and protective clothing.
