Polycarbonate bulletproof glass structure principle

The combination of PC bulletproof glass and ordinary glass requires the use of Polycarbonate（PC） materials for process production: the subdivision structure of 8+6+3PC combination of 8mm(glass)+1.52mmPVB(Glue layer)+6mm(glass)+1.25mm polyurethane(PU) materials+3mm Polycarbonate(PC) sheet.

PC plates is also called polycarbonate material, it is a kind of strong and tough thermoplastic resin, with flame retardant, wear resistance and oxidation resistance;

PU material, also known as polyurethane material, is a polymer material with various types and wide applications.

What are the characteristics of PC materials and PU materials

PC materials have higher toughness and anti-ballistic performance than ordinary inorganic glass, and the PC materials used by Tedun factory are mainly imported polymer materials from abroad, and PU materials are less common in industry. They are also imported new materials and have high adhesive type, can improve the adhesion of the PC material on the back of the bulletproof glass, and further improve the penetration resistance of the back of the bulletproof glass. For example, the F79B-25 and FDCL-3B-19 models of the bulletproof glass model, the former belongs to the old model bulletproof rating standard (GA165-1997 standard), which belongs to the 3B rating of the new GA165-2016 new standard, 19mm thick PC bulletproof glass can also withstand the 520m/s steel core 5m distance of F79B-25 class B micro-impact Bullet shooting. It can be seen that the lower thickness of the composite bulletproof glass using PC material has better ballistic resistance than ordinary glass.

To sum up, the cost of bulletproof glass with ordinary structure of bulletproof glass is indeed lower than that of PC bulletproof transparent material, but in terms of thickness and glass weight, PC structured bulletproof glass can reduce the glass thickness and glass weight by increasing its own strength to achieve protection. The balance between, for example, the demanding vaults or vehicle applications may mostly require bulletproof glass with a PC structure. The main purpose is to ensure the transparency of the vault and the mobility of the car.
