Perlite for fire door core (fire door filling material, fire door raw material) is mainly used as filling material for fire doors and security doors. Good fireproof, heat insulation and sound insulation performance, which is higher than that of aluminum silicate wool and rock wool. Fire door core perlite is a new type of fire door filling material with low cost, excellent fire protection performance and good environmental protection performance.

Good fire resistance

Perlite is used as the filling material for fire doors, which can play a better role in fire prevention. All materials used for environmental protection are environmentally friendly products and have no pollution. The product consists of glass fiber reinforced material and inorganic binder.

Environmental protection material

Perlite used as the filling material for fire doors has the characteristics of incombustibility, non-explosion, water resistance, oil resistance, chemical corrosion resistance, non-toxicity and good mechanical strength, and the products can be sawed, drilled and planed. High fire resistance, in the simulated combustion test, the flame will not be deformed when the highest temperature reaches 800 degrees, and it has good fire resistance and flame resistance.

low cost

As a filling material for fire doors, perlite for fire doors is cheap and suitable for all kinds of fire-proof materials. Perlite fire-proof board is molded from expanded perlite powder and high-temperature fire-proof adhesive, which is suitable for filling materials of wood fire-proof doors and steel fire-proof doors, and is a substitute product of aluminum silicate wool and rock wool.

Various specifications

Perlite used as the filling material for fire doors has the advantages of light bulk density, high fire resistance, high compressive strength, low thermal conductivity, non-flammable, non-toxic, tasteless and pollution-free. Product specification: product trademark: product model: price description.
