About Bromo butyl 2235

Bromobutyl rubber (BIIR) is a synthetic, halogenated elastomer prized for its exceptional gas impermeability, chemical resistance, and heat aging resistance. It is primarily used in tubeless tire inner liners for superior air pressure retention, and as pharmaceutical closures (stoppers, plungers) due to its high purity, low extractables, and stability.
