Product

Our UL94 V0 Fire-Retardant Battery Seals Silicone Sponge Sheet is a high-performance flame-retardant silicone foam material designed specifically for battery sealing, gasketing, cushioning, and thermal insulation applications. It combines excellent compressibility with reliable flame resistance, making it an ideal sealing solution for EV battery packs, ESS battery modules, battery boxes, BMS housings, and other safety-critical battery systems.

The silicone sponge structure provides soft compression and good recovery, allowing the sheet to form a tight seal against dust, moisture, air, and other environmental contaminants. With a UL94 V0 flame-retardant rating, this material is suitable for applications where fire safety and long-term sealing reliability are essential. It also offers excellent resistance to high and low temperatures, ozone, UV, and aging, ensuring stable performance in demanding operating conditions.

A closed-cell silicone sponge foam sheet engineered to meet the stringent UL 94 V-0 flammability standard, ensuring exceptional flame retardancy. This material combines high-temperature resistance (-60°C to +200°C), excellent compression set resistance, and superior sealing properties. Ideal for gasketing, insulation, and vibration damping in electronics, automotive, aerospace, and industrial applications where fire safety is critical.
