Special fireproof glass refers to the glass with special composition as glass substrates. It is mainly classified as borosilicate fireproof glass, aluminosilicate fireproof glass and glass-ceramics fireproof glass. Its common characteristics are: due to the different composition, the softening point of glass is higher, which can generally reach above 900 C, and the coefficient of thermal expansion is low. Under strong flame, it will not burst or deform due to high temperature. It has the advantages of high softening temperature and low coefficient of thermal expansion. It is a high quality work in fire-proof glass.
