Fireproof Insulation Grade Ultrafine Powder

Unlike lightweight organic insulation materials that pose fire risks, our inorganic composite powder is non-combustible, making it a core component in fireproof boards, insulation mortar, lightweight cement panels, and fire-resistant coatings. When blended into cement-based mixes, it reduces the material’s density without sacrificing compressive strength—test results show that even at high dosages, the 28-day strength remains sufficient for load-bearing insulation applications. The ultra-fine particle size creates a porous yet stable microstructure, trapping air pockets to enhance thermal insulation while maintaining the structural integrity of the building envelope.

Beyond fire safety and insulation, this product improves the workability of cement-based mortars, reducing shrinkage and cracking during curing—a critical issue for insulation materials exposed to temperature fluctuations. It also enhances the product’s resistance to high temperatures, preventing structural degradation during fires and maintaining insulation performance when it matters most. For manufacturers of green building materials, YL Cement-Based Fireproof Insulation Ultrafine Powder is a sustainable choice that reduces reliance on clinker, lowers carbon emissions, and meets stringent international fire safety and energy efficiency standards, making it ideal for residential, commercial, and industrial construction projects.
