Bulletproof glass of a jeweler's window after a burglary attempt. The Mona Lisa behind bulletproof glass at the Louvre Museum. Bulletproof glass, ballistic glass, transparent armor, or bullet-resistant glass is a strong and optically transparent material that is particularly resistant to penetration by projectiles, although, like any other material, it is not completely impenetrable.
The main polycarbonate material is produced by the reaction of bisphenol A (BPA) and phosgene COCl 2. The overall reaction can be written as follows: The first step of the synthesis involves treatment of bisphenol A with sodium hydroxide, which deprotonates the hydroxyl groups of the bisphenol A. [6] (HOC 6 H 4) 2 CMe 2 + 2 NaOH → Na 2 (OC 6 ...
The desired result is a material with the appearance and light-transmitting behaviour of standard glass, which offers varying degrees of protection from small arms fire. The polycarbonate layer, usually consisting of products such as Armormax, Makroclear, Cyrolon, Lexan or Tuffak, is often sandwiched between layers of regular glass. The use of ...
This is a list of some physical properties of common glasses. Unless otherwise stated, the technical glass compositions and many experimentally determined properties are taken from one large study. [1]
The windows are bullet resistant polycarbonate, measuring 1.5 in (38 mm) thick on the windshield and 0.5 in (13 mm) thick on the sides. [2] The TIV weighs approximately 14,000 lb (6,400 kg) fully loaded [ 3 ] and is powered by a 7.3 litre Ford Powerstroke turbocharged diesel engine manufactured by Navistar-International , otherwise known as the ...
Dr. Daniel W. Fox and LEXAN polycarbonate. Dr. Daniel W. Fox (May 14, 1927 – February 15, 1989) was an American polymer chemist who is often regarded as the father of LEXAN. LEXAN is the flagship product of SABIC Innovative Plastics (formerly GE Plastics) and is used in everything from CDs and
The 19.3 per cent efficiency record is still a long way off other solar cell technologies, with researchers passing the 30 per cent barrier last year with a tandem design that used the so-called ...
The larger circular clear black area represents the larger outer side of the thick one-piece plastic cone "window". Being transparent and durable, PMMA is a versatile material and has been used in a wide range of fields and applications such as rear-lights and instrument clusters for vehicles, appliances, and lenses for glasses.
