Borosilicate Glass

borosilicate glass I. 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) II.
