3mm Heat Strengthened Borosilicate Glass Sheet Heat Resistant Borosilicate 3.3

About Borosilicate 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 waste, where the waste is immobilised in the glass through a process known as vitrification (contrast with Synroc).


Advantage of Borosilicate Glass:

  1. High temperature resistant.
  2. Excellent thermal shock stability making them more dimensionally stable.
  3. High transmission to 85%.
  4. Electric insulation ,it is 10000 times of usual glass.
  5. Low thermal expansion.
