halobutyl
Quick Summary
Halobutyls, specifically BIIR (bromobutyl rubber) and CIIR (chlorobutyl rubber), are synthetic polymers derived from butyl rubber (IIR). Butyl rubber itself is created by copolymerizing isobutylene with a small amount of isoprene. This process results in a material valued for its chemical inertness, resistance to gases, and durability against weather.12
The key characteristic of halobutyls is the addition of bromine or chlorine to the isoprene component of butyl rubber. This modification allows for faster curing times and the use of different curing agents compared to standard butyl rubber. These properties make halobutyls easier to integrate and cure with other types of rubber in composite products. Halobutyls share many of the desirable traits of butyl rubber, such as low gas permeability and resistance to oxidation and ozone.12
