Product Description
Tempered borosilicate sight glass borosilicate glass disc
Product Description:
Borosilicate glass disc , borosilicate float glass, borosilicate sight glass
Borosilicate disc 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.
Baode optical glass can produce 3.3 high borosilicate glass disc, 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 disc
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)

1.Safety Performance: Tempered glass will appear hurtless obtuse angles when breakage.
2.Strong Performance: Four times more than ordinary glass.
3.Heat stability Performance: Three times more than ordinary glass, could bear the temperature change of about 200°C.
4.Tempered glass has a very good performance of anti-curve, anti-impact intensity.
5.Once tempered glass breakage occurs, the glass could break into small fragments, which are harmless to human body.
