Products Description

Rock wool board (Stone wool board), also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. It was successfully measured in June 1981. Rock wool board is a new type of thermal insulation, Flame-proof and sound-absorbing materials.
Rock wool board is an artificial inorganic fiber processed by high-temperature melting. It has the characteristics of light weight, small thermal conductivity, heat absorption, and non-combustibility. The initial development is a common application type in construction, and it is mostly used in industrial buildings. Application Types and Basic Requirements".

Products feature

fire protection
The raw material of the outer wall rock wool board is natural volcanic rock, which is a non-combustible building material and fireproof material.
Main fire characteristics:
☉It has the highest fire protection grade A1, which can effectively prevent the fire from spreading.
☉Dimensions are very stable and will not elongate, shrink or deform in a fire.
☉High temperature resistance, melting point higher than 1000℃.
☉Do not produce smoke or burn droplets/fragments in a fire.
☉It will not release substances and gases harmful to the environment in a fire.
heat insulation
The fiber of the rock wool board for the exterior wall is slender and flexible, and the content of slag balls is low. Therefore, the thermal conductivity is low, and it has excellent thermal insulation effect.
Sound absorption and noise reduction
Rock wool is an ideal sound-insulating material. A large number of elongated fibers form a porous connection structure, which determines that Shida rock wool is an excellent sound-absorbing and noise-reducing material.
Hydrophobic
The hydrophobic rate 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 test of ASTM C1104 or ASTM1104M method, the mass moisture absorption rate is less than 0.3%.
non-corrosive
Rock wool has stable chemical properties, PH value is 7-8, and is neutral or slightly alkaline. It is suitable for carbon steel, stainless steel,
Metal materials such as aluminum have no corrosion.
safety and environmental protection
After testing, rock wool does not contain asbestos, CFC, HFC, HCFC and other substances harmful to the environment. 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)
