First it got commercialized in 1943. The primary attributes of butyl rubber are excellent impermeability/air retention and good flex properties, resulting from low levels of unsaturation between long polyisobutylene segments. Tyre innertubes were the first major use of butyl rubber. The development of halogenated butyl rubber (halobutyl) in the 1950s and 1960s greatly extended the usefulness of butyl by providing much higher curing rates and enabling covulcanization with general purpose rubbers such as natural rubber and styrene-butadiene rubber(SBR). These properties permitted development of more durable tubeless tires with the air retaining innerliner chemically bonded to the body of the tire. Tire innerliners are by far the largest application for halobutyl today. Both chlorinated (chlorobutyl) and brominated (bromobutyl) versions of halobutyl are commercially available. In addition to tire applications it also has good impermeability, weathering resistance, ozone resistance, vibration dampening, and stability make them good materials for pharmaceutical stoppers, construction sealants, hoses, and mechanical goods.
