The high strength of bulletproof glass and its material, production process is inseparable, bulletproof glass is mainly made of conventional glass + high strength high quality plastic by high temperature and high pressure, processed in a vacuum environment, belongs to the composite material. The firmness of bulletproof glass and its thickness is proportional to the two pieces of conventional glass interlayer of high strength high quality engineering plastic is mainly PVB is now used in glass of the best quality glass bonding material, laminated glass bonding layer all known as laminated layer, bulletproof glass is actually laminated glass production process. According to the national safety standards, according to the protection level needs, processed into a strong sandwich glass has the effect of bulletproof, so it is called bulletproof glass.

Conventional bulletproof glass specifications we use are three-layer structure, which is also the lowest level of bulletproof specifications, generally 8m+8m+8m, 5m+10m+5m, 5m+12m+5m, 3 thickness respectively represents the thickness of the three layers of composite material.

Bulletproof glass and laminated glass are the same from the material, but why can play a bulletproof effect, the material we know in the sandwich layer of PVB, there is a layer of PVB can play a bulletproof effect. Bullet-proof glass maintained a common glass appearance and performance, this layer of PVB clamp sub main play when strong burst, hit the glass strength safe bulletproof glass can be within the scope of protection to the front glass pieces sticky sticktite, improve overall soundness of the glass, the glass of the back without a splash, but bullets bullet-proof glass facade bulletproof layer, Thus can play a bulletproof effect.

Bullet-proof glass must be in the main purpose of protecting people's life and property security, and safety performance is proportional to the thickness of structure, professional assessment of bulletproof glass is mainly see certificate report of bulletproof glass, bulletproof glass is not completely, but within the national standard of bulletproof level are all can help us to resist the bulletproof level of conventional weapons fire damage.
