BOROSILICATE FLOAT GLASS DESCRIPTION
Bolipai GLASS Borosilicate glass has a very low thermal expansion coefficient, about one-third that of ordinary glass. This reduces material stresses caused by temperature gradients, thus making it more resistant to breaking. This makes it a popular material for objects like telescope mirrors, where it is essential to have very little deviation in shape. It is also used in the processing of high-level nuclear waste, where the waste is immobilised in the glass through a process known as vitrification (contrast with Synroc).


BOROSILICATE FLOAT GLASS 3.3
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;
