Wholesale Perfect Fire Resistant Performance High Strength Acoustic Mineral Wool Insulation Rock Wool Board Panel Plain Slab

The raw material of the exterior wall rock wool board is natural volcanic rock, which is a non-combustible building material and fireproof material. Main fireproof characteristics:
☉ It has the highest fireproof grade A1, which can effectively prevent the spread of fire.
☉ The size is very stable and will not stretch, shrink or deform in a fire.
☉ High temperature resistance; melting point is higher than 1000 °C.
☉ No smoke or burning droplets/fragments are produced in a fire.
☉ No substances and gases harm

The fibers of the exterior wall rock wool board are slender and flexible, with a low slag ball content. Therefore, the thermal conductivity is low and it has excellent thermal insulation effect.

Rock wool is an ideal sound insulation material. A large number of slender fibers form a porous connection structure, which determines that Shikeda rock wool is an excellent sound absorption and noise reduction material.

The hydrophobicity of hydrophobic rock wool products can reach 99.9%; the water absorption rate is extremely low, and there is no capillary penetration. Moisture resistance In an environment with high relative humidity, the volume moisture absorption rate of rock wool is less than 0.2%. According to the ASTMC1104 or ASTM1104M method test, the mass moisture absorption rate is less than 0.3%.

Rock wool has stable chemical properties, a pH value of 7-8, and is neutral or weakly alkaline. It has no corrosion to metal materials such as carbon steel, stainless steel, and aluminum.

Rock wool has been tested to contain no asbestos, CFC, HFC, HCFC and other environmentally harmful substances. It will not be corroded or produce mildew and bacteria. (Rock wool has been identified as a non-carcinogenic substance by the International Cancer Research Authority)
