Butyl

We live in a rapidly-evolving world with ever-changing requirements. Exxon™ butyl rubbers provide critical performance attributes, enabling key industries such as tire manufacturing, automotive, and pharmaceutical to adapt quickly and even gain market share. Our broad range of consistent quality products allows the development of specific solutions to many current and future challenges:

  • Environmental pressure and fuel efficiency demands force the automotive industry to work to decrease CO2 emissions continuously. Fuel-efficient tires with innerliners made with halobutyl rubber can reduce fuel consumption and emissions.
  • Although electric vehicles do not emit CO2, driving range remains a concern. Tire manufacturers can provide automakers with an extra boost by developing EV-specific tires with innerliners made with top-of-the-line Exxpro™ 3563.
  • Autonomous vehicles will drive and interact without human participation, increasing the risk of insufficient monitoring. Thousands of tire-related crashes already occur every year, and this will compel self-driving car manufacturers to develop technology and high requirements for their vehicles and tires.
  • The Pharmaceutical industry's development of new or improved medical drugs and medications increases the need for high-grade stoppers. Exxpro™ specialty elastomers are a cost-effective super-clean solution.

Exxon™ butyl rubber to top-of-line Exxpro™ specialty elastomers, Exxonmobil provides top quality products, technical expertise, and global supply reliability to help you succeed.
