Exxon halobutyl rubber is the world’s most widely used butyl rubber for tire innerliners. It provides tire innerliners with the outstanding inflation pressure loss rate (IPLR) and very reliable performance that have made it the most widely used butyl rubber for innerliners.
Key benefits include:
- Halobutyl rubbers (Exxon™ bromobutyl and Exxon™ chlorobutyl) can be vulcanized with other rubbers
- Low permeability
- High heat resistance
- Excellent flex cracking resistance
- Processability
The higher the halobutyl content in the innerliner, the greater the durability of the tire. The superior air barrier performance of halobutyl innerliners prevents carcass deterioration in passenger and truck tires.
