Is Bulletproof Glass For Bullet Proof Doors A Composite?

Polycarbonate is a plastic 30 times stronger than that of a single-strength glass and 17 times stronger than single-strength glass of the same thickness. It is a transparent (transparent), soft and malleable plastic with very high strength, which is one-sixth of the weight of glass.

Polycarbonate composite glass, processed from glass and polycarbonate, mainly provides effective bullet-proof and impact-resistant glass for bullet proof doors for jewellery shop.

Once the glass and polycarbonate are combined, the overall strength can withstand shocks and shocks. Conventional bulletproof glass for bullet proof doors is composed of high-temperature, high-pressure laminated glass and polycarbonate. Also varies according to the requirements of the protection level.

Whether the substrate is acrylic or a combination of glass and polycarbonate, the end result is a transparent barrier that can prevent certain types of gun attacks.

Innovative glass and bulletproof glass technologies

While no material can truly be “bulletproof” glass, Insulgard Security Products offers innovative glass and bulletproof glass technologies to provide physical protection against ballistic attacks.

Bulletproof glass, ballistic glass, transparent armor, or bulletproof glass are durable and optically transparent materials that are particularly resistant to bullet penetration. More properly called bulletproof glass (because no glass is completely bulletproof). It consists of several layers of hard glass with “interlayers” of various plastics.

Sometimes there is a last inner layer of polycarbonate (a tough type of plastic) or plastic wrap to prevent “chipping”. When dangerous glass or plastic fragments are shattered by a bullet.

A combination of two or more types of glass bullet proof doors

It is usually made from a combination of two or more types of glass, hard and soft. The refractive index for both glasses used in the bulletproof layers must be nearly the same in order for the glass to remain transparent. And allow a clear image without distortion through the glass.

As you can imagine, the thickness of these plates (or acrylic) determines the resistance of the glass to bullets. The laminated glass layer consists of glass sheets bonded together with polyvinyl butyral, polyurethane, Sentryglas.

In this case, the glass is made of polycarbonate formed by the reaction of bisphenol A and phosgene, and is stacked with other plastics to provide greater impact resistance.

Inner layer of a hard plastic called polycarbonate

Sometimes we can also find the last inner layer of a hard plastic called polycarbonate, which helps prevent the glass from breaking when hit by a bullet and the formation of dangerous plastic or glass shards.

However, the big difference between regular glass and bulletproof glass is that the latter has layers of plastic sandwiched between the glasses. That not only absorb but also dissipate the energy of the bullet.

In other words, if you hold a piece of bulletproof glass in front of you and someone shoots at you. The bullet will slow down significantly when it penetrates the glass, causing less damage (if any) than any other type. Bullets fired from weapons that are never larger and more powerful than those designed to protect glass will bounce off the glass.

Bulletproof glass is a multi-layer composite material that can slow down the speed of hitting bullets and can withstand a lot of heat and pressure. Bulletproof laminated safety glass. Also known as bulletproof glass, is a composite product made by bonding at least three pieces of glass with various synthetic adhesives between layers.

A combination of multiple layers of glass and transparent flexible material

Bulletproof glass consists of a combination of multiple layers of glass and transparent flexible Avant-grade material, as well as a polycarbonate spacer that allows bullets to be absorbed without passing through them.

The material itself is a multi-layer laminated glass of various thicknesses, depending on the degree of threat. It should technically be called a bulletproof laminate composite, but it doesn’t sound very good.

It simply stops bullets without regard to the fact

Bulletproof glass is often considered “bulletproof” and it is assumed that it simply stops bullets without regard to the fact that it fires at the glass from a small pistol to rockets. Regular glass shatters into radiant cracks from the bullet entry point. And the glass does nothing to slow down the bullet’s pulse.

In fact, shards of glass from a bullet can be as deadly as the bullet itself. Glass, which is much harder than plastic, flattens the bullet, and plastic deforms to absorb the rest of the energy.

The layers of polycarbonate for bullet proof doors

While the layers of glass inside bulletproof glass can break, the layers of polycarbonate that are attached to the glass prevent them from shattering and shattering. And thus the entire structure remains intact. Unlike regular glass, which fragments fly all over the place.

Among the most common uses for bulletproof glass are banks. The boxes the cashier uses to exchange money and documents with clients. As well as the thick windows behind which they sit, usually bulletproof and government buildings.

This type of glass is a high quality polyacrylic combined with layers of annealed or tempered glass and has a thickness of 7.9 mm to 18 mm. In addition to ballistic protection, this glass also provides up to 60 minutes of resistance. In the event of a prolonged attack. By an intruder using a simple one-handed weapon.

A solid piece of acrylic provides its bulletproof properties

To increase security to 3 – capable of withstanding at least three hits from. 44 Magnum – Total Security Solutions inserts 1 bulletproof acrylic glass between two sheets of polycarbonate, transforming it. Into an acrylic LP (laminated polycarbonate) window.

A solid piece of acrylic provides its bulletproof properties while maintaining transparency when the glass is 1.25-1.375 inches thick. Provides Level 1 protection against 9mm weapons.

Between the two glasses there will be something like polycarbonate (very strong but transparent plastic).

Although they also use a glass-plastic sandwich, plastic is composed of ethylene vinyl acetate, acrylic glass, polycarbonate. Everyone knows that this is a great shatterproof alternative to glass.

The process of making this sandwich is called lamination. So when it comes to bulletproof glass you will see references to laminated glass or laminated polycarbonate.

For example, a Level 3 glass-coated polycarbonate. Capable of stopping three shots of a .44 Magnum is a 0.375 “layer of glass, a thin layer of polyurethane, and another 0.375” glass sheet. The final “layout” can consist of 2-5 glasses and 1-2 layers of polycarbonate.

All in all

The bulletproof glass in glass-clad polycarbonate is a multi-layer composite laminate. That combines polycarbonate and glass using special high-adhesion polyurethane interlayers that account. For the expansion / contraction difference of both materials.

StormSheild uses high quality laminates specially developed during the manufacturing process. It’s made of layers of glass and resin, like the thick pile of windshields on modern cars.

Depending on the level of protection, weight and cost. It can be combined with all ultra-transparent materials available thanks to human technology, such as glass, acrylic, polycarbonate, ceramics.
