| White to amber bales. Regular cure rate grade. Exxon™ bromobutyl rubber is derived from halogenating butyl rubber with bromine in a continuous process. It is structurally similar to Exxon™ chlorobutyl rubber and produced through the same halogenation process. Bromobutyl rubber grade slate offers a range of polymer viscosities and cure responses, reflecting adjustments in functionality and additives content. Compared with regular butyl rubber, Exxon bromobutyl rubber provides faster and more stable cure through carbon-carbon linking. Benefits: Low permeability to air, gases and moisture, Low glass transition temperature similar to regular butyl, Wide vulcanization versatility, Fast cure rates, Processing safety: no nitrosamines or nitrosamines precursors. Exxon bromobutyl rubber is a copolymer of isobutylene and isoprene. Information provided by ExxonMobil. |
