Boost your tire performance  

Tire performance for the new mobility

Mobility is changing around the world. Are you keeping up? You can quickly and affordably produce high-performance tires that meet the challenges of today’s evolving demands with Exxpro™ 3563 specialty elastomer – the world’s most advanced material for innerliners1.

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

As mobility cultures evolve, tires that meet the next level of performance can gain a greater share of the market. Don’t be left behind. Tap into our test data and technical expertise, as well as initial formulations, to save time and money while developing next-generation tires that can boost your business.

    Well suited for today’s and tomorrow’s automotive trends

    Develop new tire designs that meet the increased demands created by electric and new energy vehicles (NEV) and evolving driving cultures.

  • Gain a competitive edge

    Lead the marketplace by meeting tomorrow’s needs today.

Advanced chemistry. Advanced performance

Inclusion of high p-methyl styrene concentrations leads 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
