Features of Heat-resistant High Borosilicate Glass:

--High borosilicate glass (also known as hard glass) is a special glass material with

low expansion rate, high temperature resistance, high strength, high hardness, high smoothness, high transmittance and high chemical stability.

--The main component of high borosilicate glass is boron accounting for 12.5-13.5%, silicon accounting for 78-80%,

so the acid resistance of high borosilicate glass is excellent, and the strain temperature difference of high borosilicate glass is 560 degrees.

--Therefore, it does not contain toxic substances, and the high temperature resistance and acid resistance of borosilicate make it difficult to precipitate harmful substances in daily use.
