Product Details

Bromo butyl rubber BIIR is a copolymer rubber of bromo isobutylene and isoprene. It is derived from halogenating butyl rubber with bromine in a continuous process. Bromo butyl rubber products possesse other fundamental advantages including stability at high temperatures, rejuvenating capabilities, stronger resistance, increased adhesion to other rubbers and metals, and lastly, improved ozone and environmental resistance.
