                                 Product Description
                    Manufacture 19 mm heat resistant borosilicate sight glass   
   
Specifications
1. Excellent visual effect
2. Powerful effect on Fire, hydrolysis and Chemical Resistance
3. High resistance to thermal shock.
Bolipai 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;
