Syensqo Launches New Xencor XTreme Glass Fiber PPA for Battery Thermal Runaway Protection

January 03, 2024

Syensqo, a global supplier of specialty materials, has introduced Xencor XTreme, a new range of long glass fiber PPA solutions for battery applications. These solutions are designed to resist thermal runaway and propagation, a critical safety feature for electric vehicle batteries. Xencor XTreme PPA LGF grades can withstand direct flame exposure at 1000℃ for over 10 minutes, providing ample time for vehicle evacuation in the event of a thermal runaway. This meets the latest global regulations in Europe, China, the United States, and other countries.

The materials are designed with a V-0 UL 94 flammability rating and maintain excellent electrical insulation even after flame exposure, which helps to prevent thermal runaway in batteries. Additionally, the material has a high glass transition temperature (Tg), ensuring the dimensional stability of the parts under battery operating conditions.

Xencor XTreme is suitable for battery components such as overmolded busbars, module end plates, and fixtures. It offers high stiffness, strength, and impact resistance, as well as best-in-class electrical insulation with a comparative tracking index of >600 volts, and high dielectric strength.

Brian Baleno, Head of Marketing Automotive at Syensqo, said, “Xencor XTreme extends our broad portfolio of battery solutions. This unique product range gives engineers the freedom to address some of their biggest challenges in terms of safety, power density, security, and lightweighting.”
