Laminated and Bulletproof Glasses

A PVB layer is used between security glass to create laminated and bulletproof glass. These PVB layers are connected by Autoclave Machine. By adding more layers of PVB and security glasses, bulletproof glasses are made. This glass doesn’t scatter by a bullet. The possibility of glass particle thrown at the time a bullet hits the glass is zero.

PVB holds the glass particle together. The thickness of laminated glasses depends on the application.

Laminated and bulletproof glasses are stronger and more resistant than normal glasses that is because of their structure.

Bulletproof glasses are usually used for banks, governmental, political and army cars, and showcases of jewelry shops. Currently, bulletproof and anti-theft glasses are made of glass and hard plastic (polycarbonate of acrylic glass). PVB is inserted between these glass or plastic layers. Then, they undergo heat and pressure.

This process is done in a vacuum to prevent air from penetrating the layers. Because air weakens the glass and deviates the light.

The Difference Between Bulletproof Glass and Normal Glass

They are significantly different. Bulletproof glasses are a type of laminated glasses that is made by increasing the glass and plexiglass.

This glass breaks if a bullet hits it but it doesn’t scatter so the bullet doesn’t pass through it.

Bulletproof glass is made of polycarbonate layers that are compressed between glass layers. This compressed part is called “laminated”. It can be 10 times thicker than normal glass. So it is heavy.

When a bullet hits the glass, the energy of the bullet distributes to the whole surface. Because energy is divided between different layers of glass and plastic, energy is absorbed quicker. This reduces bullet speed so it doesn’t have enough energy to pierce or damage the glass.
