It is mainly composed of glass and high toughness materials. Bulletproof glasses from different manufacturers have different properties, but they all have the same feature, that is, good transparency, impact resistance, strong shock resistance and not easy to break. Therefore, different materials can be used to process bullet-proof glass according to different needs.
Bulletproof glass has the following three characteristics:
First, the transparency is good, and the transparency of bulletproof glass is generally above 80%.
Second, shock resistance and strong earthquake resistance. Ordinary glass cannot withstand high-intensity shock waves and strong vibrations, and bullets fired from a long distance can crush ordinary glass. Bulletproof glass can effectively protect 1 to 6.
Third, it is not fragile. Bullet-proof glass is not fragile, even if a bullet with strong blasting power comes, only a small hole can be made, so that there will be no accident of glass fragments hurting people.
There are many bullet-proof glasses in China, but most of them are laminated. The new bullet-proof glass is made of PVB film, SGP film, TPU film, PC board and other materials.
