Non-flammable; this product is made of special inorganic non-flammable mineral fibers, with a fire rating of A1.

2. High-temperature resistance: After one hour of burning at 1300 degrees, the physical properties remain unchanged and no deformation occurs; the chemical properties also do not change, and it can still be used after being fired.

3. Energy-saving: Thermal conductivity of 0.048-0.058, tensile strength around 0.2, compressive strength around 0.47, water absorption rate around 8%, specific gravity from 80 kg to 170 kg, adjustable in weight as needed, recommended around 150 kg.

4. Environmental Protection: No waste, wastewater, or emissions are produced during the production process. The fire burns smokeless and odorless, and the by-products generated during production can be reused. The workers are not at risk of silicosis, and there is no harm to the surrounding environment.
