ExxonMobil branded Tire

Bromobutyl  

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.

Our bromobutyl rubber gradeslate 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
