Rock wool board is a natural basalt as main raw material, melting at high temperature, high-speed centrifugal equipment manufacturing inorganic fiber, while adding a special binder and dust oil, and then heat cured and made into a variety of different requirements rock wool insulation products. 

 Specification: (mm) length 1000, width 630, thickness 30-120 

 Bulk Density: (kg/m3) 80,100,120,150 

 Scope of application: 

 For the plane and the radius of curvature larger tanks, boilers, heat exchangers and other equipment and building insulation, heat insulation and sound absorption. Waterproof rock wool board more suitable for the rainy, wet with water the environment, the moisture absorption rate of 5%, 98% of the hydrophobic rate.
