Cheap Price Thermal Insulation Rock Wool Board Basalt Fiber Slab 50mm Fireproof
Fireproof
Exterior rock wool board raw materials using natural volcanic rock, is non-combustible building materials fireproof materials.
Main fireproof characteristics.
☉With the highest fireproof grade A1, it can effectively prevent the spread of fire.
☉Size is very stable, will not elongate, shrink or deform in the fire.
☉High temperature resistance, melting point higher than 1000℃.
☉Does not produce smoke or burning droplets/debris in a fire.
☉Does not release substances and gases harmful to the environment in a fire.
Thermal insulation
Exterior rock wool board has thin and flexible fibers and low slag ball content. As a result, the thermal conductivity is low and it has excellent heat insulation effect.
Sound absorption and noise reduction
Rock wool is an ideal sound insulation material. The large number of long and thin fibers forming a porous connection structure determines that Schickardt rock wool is an excellent sound-absorbing and noise-reducing material.
Water Repellency
Water repellent rock wool products can reach 99.9% water repellency; water absorption rate is very low, no capillary penetration.
Moisture resistance
Rock wool has less than 0.2% moisture absorption by volume in an environment with high relative humidity, and less than 0.3% moisture absorption by mass when tested by ASTMC1104 or ASTM1104M method.
Non-corrosive
Rock wool is chemically stable, with a PH value of 7-8, neutral or weakly alkaline, and is non-corrosive to carbon steel, stainless steel,
Aluminum and other metal materials are not corrosive.
Safe and environmentally friendly
Rock wool is tested and does not contain asbestos, CFC, HFC, HCFC and other environmentally harmful substances. It will not be corroded or produce mold and bacteria. (Rock wool has been recognized by international cancer research authorities as a non-carcinogenic substance)
