CellBlockEX is the environmentally-friendly, mineral-based extinguishing agent used for fire fighting and prevention of problematic fires including metal, lithium-ion battery cells, and combustible liquids. The small lightweight spheres of CellBlockEX are composed of non-crystalline glass granulates repurposed from recycled glass with tiny pores on the inside. The engineered formulation of grain sizes produces optimal fire suppression results, and can be adjusted for varied industrial applications. Since the granulate is 100% mineral based – it’s safe for you and the environment.
