Fabric increases EV battery safety

Asahi Kasei’s new grade of LASTAN™ flame-retardant, highly flexible nonwoven fabric enhances EV battery safety with excellent resistance to flames and particle blasts. Conventional mineral-based materials for thermal runaway protection tend to be heavy and brittle, making them difficult to adapt to complex shapes. The highly flexible LASTAN is a non-mineral fabric characterized by high flame resistance and good electrical insulation with a special coating that augments abrasion resistance. It is easily processed with ordinary tools, contributing to a simplified manufacturing process.
