Product Description

APPLICATION
Borosilicate 3.3 serves as a material of truly functional 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. Iatrology and bio-engineering;
8. Safety protection (bullet proof glass);
