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