Product Description
GSC Series Rigid Foam are renowned for their distinctive characteristics, which include:
◆GSC ceramicized solid silicone is a high-performance material meticulously developed for thermal protection and cable insulation scenarios, especially in environments requiring extreme heat resistance and fire safety.
◆ Extreme Thermal Endurance: Can withstand 1000℃ open flame without cracking and ceramicizes into a stable supporting structure. It also features long-term resistance to 1200℃ without cracking or burning through.
◆ Fire Retardancy: Meets the UL94 V-0 flammability rating, delivering outstanding fire suppression and propagation resistance.

◆ Fire Retardancy: Meets the UL94 V-0 flammability rating, delivering outstanding fire suppression and propagation resistance.
◆ Longevity & Stability: Exhibits superior high-temperature stability and aging resistance, ensuring a prolonged service life even in harsh operating conditions.
【Applications】
◆Application Spotlight: Battery Thermal Runaway Protection: A critical application lies in electric vehicle (EV) battery packs (and other energy storage systems). As depicted in the schematic, the material acts as a thermal barrier between battery modules and cells. When thermal runaway occurs (or during external fire exposure), GSC ceramicized silicone ceramicizes to form a heat-insulating layer, preventing heat propagation and protecting adjacent components.
◆Laboratory and field tests validate its performance: the temperature curve graph shows that while the exposed side reaches ultra-high temperatures (exceeding 1200℃), the protected “backside” maintains a significantly lower, safe temperature—proving robust thermal insulation.
