Description
- 💎 boro3.3 belongs to a kind of fireproof glass. High borosilicate glass is a kind of glass melting by heating in the glass, which is made by advanced production technology, taking advantage of the conductivity of glass at high temperature. High borosilicate glass has very low coefficient of thermal expansion, high temperature resistance, temperature difference of 200 ℃.
- 💎 boro3.3 has excellent physical and chemical properties. Its silicon content is over 80%. The internal structure of glass is very stable, so it has good mechanical and chemical properties.
- 💎 boro3.3 high-temperature glass fully conforms to ISO3583 international standard. Because of its low thermal expansion coefficient, it can better withstand higher temperature difference and has good flame processing performance. It is an excellent material for manufacturing heating utensils and various complicated glassware.
- 💎 This product is a customized product. After the order is confirmed, it takes about 3-5 days to complete the production. It takes a long time to form by high temperature condensation.Each of our products is manufactured by a master, who spends a lot of time firing them.
- 💎 We has more than 200 workers, providing customized glass products. Can meet all customer customization needs. If you need custom glass products, you can contact us.
