Properties of bullet proof glass
Explain bulletproof glass?
Bulletproof glass, also called ballistic glass, is a type of glass that is constructed to bear the impact of bullets and other projectiles.
Properties of bullet proof glass
The key properties of bullet proof glass has given below:
- High impact resistance:
- Multiple layers:
- Customizable thickness:
- Optical clarity:
- Durability:
- Fire resistance:
- Sound insulation:
High impact resistance:
Bulletproof glass is constructed to bear the influence of bullets and other projectiles without breaking or shattering.
Multiple layers:
Bulletproof glass is usually constructed of numerous layers of glass and polymer materials, such as
- polycarbonate
- or polyvinyl butyral (PVB),
which provide aid in the absorption and dissipation of the energy of the projectile.
Customizable thickness:
The thickness and composition of bulletproof glass can be customized to harmonize with different levels ofsafety, according to the specific demand .
Optical clarity:
Many types of bulletproof glass are constructed to be highly opaque and have good optical properties, which made them useful in applications where clarity and light transmission are important.
Durability:
Bulletproof glass is highly long lasting and resistant to
- Scratches
- Abrasion
- and other types of wear and tear.
Fire resistance:
Bulletproof glass are fire resistant and can bear high temperatures without disrupting its structure.
Sound insulation:
The sound insulating property of bulletproof glass is helpful where insulation of sound is necessary.
Which polymer is used to make bulletproof glass?
The bulletproof glass normally synthesized from laminating multiple layers of glass with a layer of polymer material in between them.
The polymer which are usually used in the formation of bulletproof glass are given below:
- Polycarbonate:
- Polyvinyl butyral (PVB):
- Ethylene-vinyl acetate (EVA):
- Acrylic:
Polycarbonate:
When making bulletproof glass, polycarbonate, a sturdy and clear thermoplastic polymer, is frequently used. It can aid to deflect projectile energy and has great impact resistance.
Polyvinyl butyral (PVB):
Frequently used as the interlayer among the multiple layers of glass in bulletproof glass, PVB is a clear, adhesive polymer. It helps to absorb and disperse the force of a projectile and has exceptional visual clarity.
Ethylene-vinyl acetate (EVA):
Glass laminated items frequently use EVA, a thermoplastic polymer. It can assist increase the durability and resistant to impact of bulletproof glass and has good adhesive properties.
Acrylic:
Acrylic is a strong and transparent thermoplastic polymer that is sometimes consumed in the production of bulletproof glass. It has good optical properties and can aid to enhance the impact resistance of the glass.
