COLOGNE, Germany—ExxonMobil Chemical has developed an inner liner material that it claims can significantly improve air retention in tires, and introduced the new material during the Future Tire—Sustainability conference in Cologne.
Branded Exxpro 3563, the high para-methyl styrene co-polymer can achieve a 50 percent improvement in air retention compared to currently used materials, according to Arancha Guisuraga, global market development manager for ExxonMobil's specialty elastomer and butyl business.
Customers can use the new product "as an additive or full halobutyl replacement depending on the performance improvement required," Guisuraga said. The product also allow tire makers to meet stringent OE air-retention specifications for advanced ICE, hybrid and EV vehicles.
Exxpro 3563 reflects ExxonMobil's drive to improve tire sustainability through low-rolling-resistance and optimized safety performance during use.
