Borosilicate glass is one kind of special float glass. The main component of high borosilicate glass is boron: 12.5-13.5%, with a silicon content of 78-80%. Therefore, the acid and alkali resistance of high borosilicate glass are very superior, with a strain temperature difference of 520°C. High-grade borosilicate glass can withstand high temperatures of 850°C and can withstand temperatures of 750°C for a long time. Its high-temperature softening point is above 850°C.
Refer to the applications, there are two series of borosilicate glass as Borosilicate fire-resistant glass (4.0) and Borosilicate heat-resistant glass (3.3) in our production.
Borosilicate fire-resistant glass (4.0) is a kind of outstanding material and this glass has a wide range of safety applications. They can be used as single or insulating glass and meet different protection requirements.
Borosilicate heat-resistant glass (3.3) is widely used in situations to meet the requirements of low thermal expansion.
