Butyl rubbers from ExxonMobil Chemical combine the barrier properties, high damping and resistance to ozone that make them ideal for tire applications. You’ll find our butyl rubbers in many tire components, including the innerliner, non-staining black sidewall, white sidewall and white sidewall coverstrip.

Applications and benefits

Manufacturing innertubes withExxon™ butyl rubber or Exxon™ chlorobutyl rubberinstead of natural rubber provides numerous benefits to the users of bicycle tires, radial truck tube-type tires and some severe service, off-road tire applications.

Benefits include:

  • Consistent inflation pressure
  • Reduction in in-use tire rolling resistance due to the better inflation pressure retention, leading to the potential for less fuel consumption
  • Longer tire life and more even-wear performance
  • Longer innertube life due to better heat stability
  • Enhanced tire durability

Recommended products:

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:

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.
