Centrifugal glass wool is a silk-like material made by fabrications of melted glass and then coating with thermosetting resin through centrifugal blowing process. By means of thermal setting, this material can be further processed into series of products for multiple purposes. It features numerous advantages: it is noncombustible, nontoxic, and resistant to corrosion; it has low weight by volume, low thermal conductivity, stable chemical property, low moisture rate and good hydrophobic. It is to date a well-recognized heat preservation, thermal insulation and sound absorption material with excellent properties. It has found wide applications. The board and blanket products made of this material have been used in heat preservation, thermal insulation and sound absorption in construction, chemical industry, electronic industry, electric power, metallurgy, energy industry and communication, presenting very good result.
