The difference between bulletproof glass and explosion-proof glass

Explosion proof glass and bulletproof glass both have defense functions, but their usage scenarios and defense principles are different.

Explosion proof glass is made by adding a certain amount of polymer or fiberglass to two or more layers of glass interlayers, making them highly resistant to explosions. This can prevent glass from shattering when subjected to external impact, prevent glass fragments from splashing, and reduce harm. Explosion proof glass is suitable for explosion-proof, bulletproof, explosive proof and other occasions.

Bulletproof glass is made by adding multiple layers of special polymers, special metal alloys, and other materials to the glass. These special materials can enhance the impact resistance, penetration resistance, and bullet resistance of glass, enabling it to effectively resist attacks such as bullets and hand grenades. Bulletproof glass is commonly used in areas such as safety doors, bulletproof windows, and bulletproof mats.

Therefore, the difference between explosion-proof glass and bulletproof glass lies in their main application scenarios and defense principles.

The difference between bulletproof glass and explosion-proof glass is mainly due to their different functionalities. bulletproof glass blocks bullets, while explosion-proof glass has a strong anti violent impact effect. Bulletproof glass is composed of three or more pieces of glass added with materials such as PVB/SGP/PC; Explosion proof glass is made by adding some polyvinyl alcohol butyraldehyde ester or EVA polymer adhesive materials on the basis of ordinary tempered glass and smelting them in a hot melt furnace.

Explosion proof glass:

Special glass made by machine processing using special additives and central interlayer, even if the glass is broken, it is not easy to fall because the central data (laminated glass) or the other side (single-sided explosion-proof glass) are connected, greatly reducing damage to personnel and furniture.

Bulletproof glass:

Bulletproof and anti-theft glass is scientifically composed of multiple transparent float glass pieces of different thicknesses and multiple PVB films, with a total thickness usually exceeding 20mm. It is required that the total thickness of higher bulletproof glass can reach 50mm or more. Metal impact can only break the glass and cannot penetrate it, thus playing a role in bulletproof and anti-theft.

What are the classifications of explosion-proof glass and bulletproof glass

Bulletproof glass can be divided into two types, one is safety type and the other is life safety type. Safe bulletproof glass, after being shot, has no splashes on its non impact surface and does not cause any harm to the human body. Life safety bulletproof glass, after being shot, may have splashes on the non impact surface, but bullets cannot penetrate the glass, which may cause secondary injury to the human body.

Explosion proof glass can also be divided into two types: ordinary explosion-proof glass and reinforced explosion-proof glass

Ordinary explosion-proof glass is a special type of glass made from single piece float glass through strengthening treatment. The surface of the strengthened glass has strong resistance to violent impact. As the thickness of the glass increases, its explosion-proof effect is constantly enhanced. The thickest thickness is usually 20 millimeters. Glass with a thickness exceeding 20 millimeters is made into explosion-proof glass, and strengthening treatment is difficult to achieve at once. For users who choose ordinary explosion-proof glass, it is necessary to be cautious.

Reinforced explosion-proof glass refers to two or more pieces of float glass sandwiched between strong and tough PVB films, which are pressed by a hot press machine and discharged as much as possible into the middle air. Then, they are placed in a high-pressure steam kettle and dissolved into the adhesive film using high temperature and pressure to form a small amount of residual air.
