3.7 borosilicate bullet-proof glass

borosilicate bullet-proof sight glass for military armored vehicles. Compared to 6.4 Mohs’scale of hardness and the same thickness of the normal float glass, 3.3 borosilicate glass has a surface hardness of 7.0, which is better in bullet-proof performance.

With 3.3 borosilicate glass, thickness will lower, weight lighter where the whole vehicle can be lighter to reach good performance of saving fuel and putting up speed.

Adopted for our tempering and laminated process, bullet-proof performance can be further improved.  The light transmittance up to 90%.
