Reduce rolling resistance, reach an exceptional IPLR

With the radical changes in mobility happening now, we need more than ever before, maintenance-free tires with the lowest possible air-loss rates. Innerliners made with Exxpro™ 3563 enable exceptional IPLR performance (< 1.8%) affecting more than just energy efficiency. It impacts the vehicle’s safety, emissions and extends tire life. It’s a difference that can be measured with real data. Compared to the global average 80% halobutyl (HB)**/ 20% natural rubber (NR) innerliner blend, Exxpro™ 3563 delivers:

  • 12% improvement in in-use rolling resistance
  • 20-50% improvement in air retention

*Inflation Pressure Loss Rate

**HB acronym includes both bromobutyl and chlorobutyl

Gain a competitive edge with Exxpro™ 3563 in your tire innerliners


Advanced chemistry, advanced performance

Inclusion of high para-methyl styrene concentrations lead to lower segmental mobility and lower free volume, resulting in significant permeability reduction compared to halobutyl rubbers.

Compound consistency

Compared to halobutyl, Exxpro™ 3563 provides compound consistency advantages:

  • Ease of manufacturing: lower heat shrinkage, higher green strength and good tack
  • Greater production output: better filler dispersion
  • Better air retention: reduced segmental mobility and bulky hpMS
