Bulletproof glass is a composite material obtained by special processing of glass (or plexiglass) and high-quality engineering plastics. It is usually a transparent material and usually includes a polycarbonate fiber layer sandwiched in a common glass layer.
Bulletproof glass is a composite material obtained by special processing of glass (or plexiglass) and high-quality engineering plastics. It is usually a transparent material, such as PVB/polycarbonate thermoplastics (usually lexan resin). Also called LEXAN PC RESIN). It has the appearance of ordinary glass and the act of transmitting light, providing certain protection for the shooting of small arms. The thicker pc board can be 136 mm thick, with a larger width of 2166 mm wide and effective time of 6664 days.
The bulletproof glass produced by different manufacturers varies. Basically, however, a layer of polycarbonate is sandwiched between ordinary glass layers. This process is called lamination. In this process, a material similar to ordinary glass but thicker than ordinary glass is formed. Polycarbonate is a rigid transparent plastic - people usually call it by its brand (Lexan, Tuffak or Cyrolon). The thickness of the bulletproof glass is between 7mm and 75mm. Bullets fired on bullet-proof glass will break through the outer glass, but the polycarbonate glass material layer can absorb the energy of the bullet, thus preventing it from penetrating the inner layer of glass. These large pieces of bullet-proof glass have been used for public purposes during the Second World War. They are usually as thick as 10.0 cm to 12.0 cm and are extremely heavy.
