Popularity is a type of fly ash hollow sphere that floats on water, featuring the following characteristics:

Grayish white in color, thin-walled and hollow, extremely lightweight. Density at 720 kg/m3 (heavy) or 418.8 kg/m3 (light), particle size approximately 0.1 mm, surface sealed and smooth.

Low thermal conductivity, with a耐火度≥1610℃, it is an excellent insulation refractory material.

Chemical composition primarily consists of silicon dioxide and aluminum oxide, featuring fine particles, hollow structure, light weight, high strength, wear resistance, high-temperature resistance, thermal insulation, and flame-retardant insulation.

Based on these characteristics, expanded polystyrene beads are widely used in the production of fire-resistant and insulating boards. These boards not only offer excellent fire resistance but also effective insulation. Their integrated installation method reduces the number of processes, lowers construction costs, and also saves on ceiling height. The fire-resistant and insulating properties of this material are due to the unique structure and chemical composition of the beads, making it an ideal fire-resistant insulating material. Additionally, the expanded polystyrene beads are water- and solvent-resistant, further enhancing their safety and durability.

In summary, the principle of the expanded perlite fireproof and insulating board is to leverage the unique physical and chemical properties of expanded perlite, including its light weight, fire resistance, and insulation features, and to provide an efficient and safe fire and thermal insulation solution through an integrated installation method.
