The centrifugal glass wool is silk-like materials made by fiberization in the tel process and spraying of thermosetting resin. By further deep processing of thermal setting, this material can be made into series of multi-purpose products. It features number-ous advantages: It is non-combustible, nontoxic, and resistant to corrosion; It has low weight by volume, low thermal conductivity, stable chemical property, low moisture rate and good hydrophobicity. 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, felt and pipe 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.
