Borosilicate 4.0 glass has the characteristics of low expansion, high temperature resistance, corrosion resistance, high mechanical strength and light weight, and has extremely wide application. The borosilicate 4.0 glass has excellent thermal shock resistance, high softening point temperature, can generate enough preheating stress, and has the density lower than that of the traditional soda-lime glass by more than 8 percent, so the borosilicate 4.0 glass is also an ideal material for replacing the traditional float glass in the field of building fire prevention.
Borosilicate 4.0 flat glass was introduced by Schott, Germany in the early 90 s, and the technology of oxy-fuel combustion, electric-boosting melting and micro-floating molding was adopted.
