2. resistance acid and alkali 
3. the competitive price 
4.good surface quality 

Borosilicate glass, borosilicate float glass, borosilicate sight glass

Borosilicate glass is one of transparent colorless glass, through wavelength is between 300 nm to 2500 nm, transmissivity is more than 90%. Coefficient of thermal expansion is 3.3. It can acid proof and alkali , the high temperature resistant is about 450°C. If course handling , the high temperature resistant can reach 550°C or so. Apply to lighting fixture , chemical industry , electron, high temperature equipment and so on.

Zeyuan optical glass can produce 3.3 high borosilicate glass, with a good appearance, high temperature, resistance strong pressure, resistance acid and alkali, high transparency, After cutting, grinding, polishing, milling, Tempered and so on process to complete. We can produce  borosilicate glass sight glasses.. 1.7,2.0,3.0,3.3,4.0,5.0,6.0,8.0,10.0,12.0,15.0,20.0,25.0 mm thickness, etc.,
The dimension and thickness can according to the requirement.(Customization)

Application of borosilicate glass

Borosilicate glass 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). Boiler, burner

8). Safety protection (bullet proof glass)
