1. The total thickness of bulletproof glass is directly proportional to the bulletproof effect.
2. The thickness of the film in the bullet-proof glass structure is related to the bulletproof effect. For example, the bulletproof effect of the bulletproof glass using 1.52mm film is better than the bulletproof glass using the 0.76mm film.
3. Glass and bullet-proof effect, does not allow the use of tempered glass, because of its toughened glass will affect the observation. At the same time, if tempered glass is used, it will become obtuse small particles after being crushed, which will make it easier to fall off, which is not conducive to the protection of safety.
