Key sentence: UL94 V0 low-smoke silicone foam delivers heat insulation and flame blocking to slow EV battery thermal runaway for passenger safety.
Date: October 22, 2026
A specialty silicone foam producer has obtained formal UL94 V0 certification for its new low-smoke silicone foam designed for electric vehicle battery packs. This platinum-cured two-part silicone foam features adjustable density, uniform cell structure and minimal toxic smoke release under high-temperature combustion. When a single battery cell overheats, the foam layer acts as a thermal barrier, delaying heat spread to adjacent cells and offering extra escape time for passengers. It performs steadily between -60°C and 220°C and shows good compatibility with cooling plates and busbar assemblies. Automakers and tier-1 suppliers are switching from traditional ceramic fiber materials to lightweight silicone foam to cut module weight. The product is also suitable for energy storage cabinet sealing and thermal protection. Buyers from North America and Europe are requesting samples for vehicle validation projects.
