How bullet proof glass is made and what make it bullet proof?
Bulletproof glass is a colloquial term for glass that is particularly resistant to being penetrated when struck by bullets. Since manufacturing glass of usable thicknesses capable of fully stopping most bullets cannot currently be done, the industry generally refers to it as bullet-resistant glass instead .. Bullet-resistant glass is usually constructed using a strong but transparent material such as polycarbonate thermoplastic or by using layers of laminated glass. The desired result is a material with an appearance and light-transmitting behavior of standard glass but offers varying degrees of protection from small arms fire . The polycarbonate layer, usually consisting of products such as Makroclear, Cyrolon, Lexan or Tuffak, is often sandwiched between layers of regular glass. The use of plastic in the laminate provides impact-resistance, such as physical assault with a hammer, an axe, etc. The plastic provides little in the way of bullet-resistance.
