Fire-resistant glass / bulletproof glass
Fireproof Glass
Fireproof GlassSYP fireproof glass comes in single-pane and laminated glass. The heat-resistant performance of fireproof glass can block flames during a fire accident, helping people prepare for an easy escape. Single-pane fireproof glass is classified as follows according to the Chinese fire resistance test standard. SYP can even produce Class 1 fireproof glass, the highest grade.
Class 1 (≥90 minutes), Class 2 (≥60 minutes), Class 3 (≥45 minutes), Class 4 (≥30 minutes). Single-pane fireproof glass can be made into coated glass, laminated glass, and composite glass.

Bulletproof Glass
Bulletproof GlassBulletproof glass is a composite material obtained by specially processing glass and high-quality engineering plastics. Bulletproof glass is a transparent material that looks no different from ordinary glass and can prevent bullets from penetrating, providing certain protection against small arms fire.
- Traditional Bulletproof Glass: Glass + Polymer Interlayer + Glass + Anti-Splash Film
- New Bulletproof Glass: Glass + Polymer Interlayer + Engineering Plastic (Lightweight and Thin)
Bulletproof Principle of Glass
-
Ordinary Glass: Energy penetrates the glass
-
Bulletproof Glass: Energy is absorbed by the laminated material
