Exxcore™ DVA resin
Making less count for more.
Exxcore™ dynamically vulcanized alloy (DVA) resin, a blend of specialty elastomer and nylon, is our next-generation resin for advanced tire innerliners. With Exxcore DVA-based innerliners, tire manufacturers can create tires that are lighter and more durable because they maintain proper air pressure far longer and roll easier.
This product is currently in development and is not yet available for commercial sales.
New versatility
Create your perfect balance of tire weight and performance.
Advanced technology
The future of tire manufacturing is cleaner and more efficient.
As light and thin as a plastic bag, innerliners made with Exxcore DVA can reduce passenger car weight by as much as 7 pounds (3.2 kg).
Tires with advanced innerliners handle better and last longer, thanks to up to 10 times better air retention.
Checking tire air pressure is a hassle for drivers. Lessen their burden with innerliners featuring leading-edge inflation pressure retention (IPR).
Innerliners made from Exxcore DVA require up to 80% less material than conventional innerliners. They also help automakers improve vehicle fuel economy and reduce CO2 emissions.
