Cover glass wool board is in the glass molten state law centrifugal injection process fibrosis spraying thermosetting resin made from filamentous material, through the thermal curing deep processing, multiple applications can be made with a series of products. It has a flame retardant, non-toxic, corrosion resistance, bulk density of small, low thermal conductivity, chemical stability strong, and low moisture absorption rate, hydrophobic good, and many other advantages, is recognized as the most superior heat preservation performance, heat insulation, sound-absorbing materials, has a very wide range of USES. Made from the material board, felt and pipe has a large number of used in construction, chemical industry, electronics, electric power, metallurgy, energy, transportation and other fields of heat preservation and heat insulation, sound absorption, noise reduction, the effect is significant.
