Glass wool is used in a molten state centrifugal blowing spray technology for fibrosis filamentous material thermosetting resin, and then after thermal curing deep processing, products can be made with a variety of uses. It has a flame-retardant, non-toxic, corrosion resistance, bulk density of small, low thermal conductivity, chemical stability, low moisture absorption, good hydrophobicity and many other advantages, is widely recognized as the most superior performance of thermal insulation, sound-absorbing materials, has a very wide range of uses. Insulation board with this material, carpets, have been widely used in construction, chemical, electronics, electricity, metallurgy, energy, transportation and other areas, sound absorption, the effect is very significant. Due to centrifugal glass wool is soft, fine fiber construction will not irritate the skin, and thus by construction units welcome, becoming the first choice of insulation.
