mineral rock wool board insulation materials

Rock wool is an ideal sound insulation material. A large number of slender fibers form a porous connection structure, which determines that Shida rock wool is an excellent sound-absorbing and noise-reducing material.
　　 Hydrophobicity
　　The water-repellent rate of water-repellent rock wool products can reach 99.9%; the water absorption rate is extremely low, and there is no capillary penetration.
　　 Moisture resistance
　　 Rock wool has a volumetric moisture absorption rate of less than 0.2% in an environment with a high relative humidity. According to the ASTM1104 or ASTM1104M method, the mass moisture absorption rate is less than 0.3%.
Non-corrosive
 
　　 Rock wool has stable chemical properties, with a PH value of 7-8, which is neutral or weakly alkaline. It is suitable for carbon steel, stainless steel,
　　Aluminum and other metal materials are non-corrosive.
Safety and environmental protection
 
　　 Rock wool has been tested and does not contain asbestos, CFC, HFC, HCFC and other substances harmful to the environment. Will not be corroded or produce mildew and bacteria.
