Borosilicate Float Glass3.3（BG33）
This revolutionary glass is made of borosilicate, a special material that combines strength and durability with an extraordinarily high heat resistance.
Whether it's functional or decorative, this magnificent material will make any project look great while helping protect against extreme temperatures up to 500°C (932°F). And because of its excellent thermal shock properties, it won't cloud over time from frequent temperature fluctuations either!
Borosilicate float glass 3.3 is a special glass material with low expansion rate, high emperature resistance, high strength, high hardness, high light transmittance and high chemical stability.
Because of its excellent performance, it is widely used in household appliances, environmental engineering, medical technology, safety protection and other fields, especially in the field of household appliances, borosilicate float glass 3.3 is widely used as the panel and inner tray of ovens and microwave ovens. In addition, because the hardness of borosilicate float glass 3.3 is 8-10 times that of ordinary glass, it is also used as bulletproof glass by many customers.
Borosilicate 3.3 serves as a material of true function and wide applications:
1). Household electrical appliance (panel for oven and fireplace, microwave tray etc.);
2). Environmental engineering and chemical engineering (lining layer of repellence, autoclave of chemical reaction and safety spectacles);
3). Lighting (spotlight and protective glass for jumbo power of floodlight);
4). Power regeneration by solar energy (solar cell base plate);
5). Fine instruments (optical filter);
6). Semi-conductor technology (LCD disc, display glass);
7). Medical technique and bio-engineering;
8). Safety protection (bullet proof glass)
High borosilicate 3.3 glass is high-temperature resistant glass, heat-resistant glass and temperature difference resistant glass. The linear expansion coefficient is 3.3 ± 0.1 × 10-6 / K, is a glass with sodium oxide (Na2O), boron oxide (b2o2) and silicon dioxide (SiO2) as the basic components. The content of boron and silicon in the glass composition is relatively high, namely, boron: 12.5 ~ 13.5%, silicon: 78 ~ 80%.
The expansion coefficient will affect the stability of glass. The expansion coefficient of borosilicate 3.3 heat-resistant glass is 0.4 times that of ordinary glass. Therefore, at high temperature, borosilicate 3.3 heat-resistant glass still maintains excellent stability and will not crack or break.
The long-term working temperature of borosilicate 3.3 heat-resistant glass can reach 450 ℃, so it is often used as the microwave oven panel. At high temperature, borosilicate 3.3 heat-resistant glass can not only work normally, but also maintain high permeability, which is convenient for users to observe the internal food state.
Our 3.3 borosilicate glass is extremely versatile too – you can use it for almost any purpose imaginable; such as microscope slides and petri dishes; kitchenware items like oven-proof baking dishes; art projects like stained-glass windows.the possibilities are endless! Its lightweight yet strong construction allows for easy transport between workspaces so you can take your creations wherever they need to go. And thanks to its crystal clear transparency, light passes through beautifully with no distortion whatsoever - making sure whatever design you come up with looks perfect every time!
