Our borosilicate float glass is made up of about 15% boron trioxide, which is that magical ingredient that completely changes the behavior of glass.
BOROSILICATE FLOAT GLASS 3.0
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. Iatrology and bio-engineering;
