Bitwater (Shenzhen) Technology Co., Ltd.’s expanded vermiculite fireproof material is a premium solution for high-temperature insulation needs. Derived from natural vermiculite, this material undergoes an expansion process to create a lightweight, porous structure with exceptional fire resistance, capable of withstanding continuous temperatures above 1200°C. It features low thermal conductivity (0.06–0.2 W/m·K), effectively minimizing heat transfer in industrial furnaces, fireplaces, and aluminium electrolytic cells. The fireproof material is non-combustible, non-toxic, and free from harmful additives, meeting strict safety standards. Available in various forms including boards and bricks, it offers versatility for different applications, with options like 400 low density for lightweight use or 500 high density for heavy-duty environments. Its durability against thermal shock and chemical corrosion ensures long-lasting performance and energy efficiency.
