Bullet proof glass material

The main components of bulletproof glass are mentioned in the introduction of bulletproof glass products, because bulletproof glass materials are mainly transparent glass materials. Bulletproof glass also has the difference in the application of different materials as different uses.

Main component

The main components of bulletproof glass materials are as follows:

• Glass material (as a transparent and safe basic material, it can effectively guarantee light transmission)
• Film material (PVB is generally used, the safest and most effective buffer material to reduce the ballistic impact caused by transition)
• Composite materials (such as Polycarbonate, Polyurethane, new materials, which can be used as substitutes for glass: advantages are light weight, high safety, higher light transmission, disadvantages: higher prices)
• Bulletproof film (the film layer plays a role in surface protection to avoid bumps and scratches, and is generally installed on the back to avoid splashing glass fragments)《How to shoot through bullet proof glass》

Bulletproof glass material price

Glass is a custom-made material, so the price of the material is also tailor-made, generally calculated at the price per square meter, because the price of ordinary glass material is tempered and is cheaper. Therefore, the price of all-glass bulletproof glass is less than US$100/㎡. Film materials are more common, unless SGP bulletproof film materials with high toughness and hardness are used.

Since polycarbonate and polyurethane materials are polymer materials, the price is higher after adding special polymer materials on the basis of basic materials, and the cost is higher due to the particularity and performance of the material combination and the complex production process
