Rockwool Department of selected basalt as the main raw material, made by high-temperature melting inorganic synthetic fibers. With light weight, small thermal conductivity, sound absorption performance, non-flammable, good chemical stability and so on. It is a new type of insulation, heat insulation, sound-absorbing material, rock wool v products in addition to the characteristics of rock wool with the general, but also has a waterproof, thermal insulation, cold insulation properties, Even in the case of wet long-term use will not occur deliquescence. According to the method of JISA95-1979 test, the hydrophobic rate of 98% or more. Because of its products do not contain fluoride (F-), chlorine (CL), so it has no corrosive effect on the equipment. It is a kind of non-combustible material tested by the Tianjin Fire Research Institute of the Ministry of Public Security. It is an excellent non-combustible material for buildings, pipes, storage tanks, distillation towers, boilers, flues, heat exchangers, fans and vehicles. Sound absorption of the ideal material.
