Branded Exxpro 3563, the high para-methyl styrene copolymer* can achieve a 50% improvement in air retention compared to currently used materials, said Arancha Guisuraga, global market development manager, specialty elastomer and butyl business ExxonMobil.
Customers can use the new product “as an additive or full halobutyl replacement depending on the performance improvement required,” Guisuraga told the conference.
The product, she said, will allow tire manufacturers to meet stringent OE air-retention specifications for advanced ICE, hybrid and EV vehicles.
The introduction, explained Guisuraga, reflects ExxonMobil’s drive to improve tire-sustainability by maintaining low-rolling-resistance and safety performance during use.
