What is high borosilicate glass?

High borosilicate glass is a glass product containing a large amount of B2O3 and SiO2, of which the content of B2O3 is between 15% and 30%, and the content of SiO2 is between 65% and 78%. Due to the presence of boron in high borosilicate glass, it has excellent properties such as high temperature resistance, acid and alkali corrosion resistance, and is not easy to precipitate harmful substances. Therefore, it is widely used in various occasions, such as chemical equipment, laboratory instruments, food packaging and other fields.
The production process of high borosilicate glass is relatively complicated, and it needs to go through multiple steps such as melting, molding, and cooling to make it. During the melting process, high-purity raw materials need to be placed in a kiln and heated to a high temperature to melt it into a liquid state, and then it is made into cups of various shapes through a special molding method. Due to the high hardness of high borosilicate glass, the surface of the produced cup is smooth and delicate, and the transparency is also very good. In addition, high borosilicate glass also has certain heat insulation properties, which can effectively prevent the transfer of heat.
At present, there are many varieties of high borosilicate glass cups on the market, in various forms, including single-layer glass cups, double-layer glass cups, vacuum glass cups, etc. These cups are not only beautiful in appearance, but also have good practical properties, such as good heat preservation performance and strong wear resistance. Therefore, whether it is for home use or display in public places, high borosilicate glass cups are a very good choice.
