China Borosilicate Sheets Glass 3.3



1) Stronger resistance to fracture;

2) Borosilicate Sheets Glass is lower than ordinary glass dense;

3) When broken, borosilicate glass sheets cracks tend to be relatively large, rather than crushed (it will unit, not split);

4) Borosilicate 3.3 glass has a low dispersion (about 65 Abbe crowns) and a relatively low refractive index (the entire visible range 1.51-1.54);

5) The linear expansion coefficient is 3.3 ± 0.1 × 10-6 / K;

6) Resistant to Water, Acid and alkali ;

7) Superior corrosion resistance;

8) It has good thermal stability, chemical stability and electrical properties, it is resistant to chemical attack, thermal shock resistance, good mechanical properties, to withstand high temperature and other characteristics.
