The Role of Bulletproof Glass

Bulletproof glass plays a crucial role in security protection. Its core technical parameters include ballistic resistance level (e.g., NIJ Level III, capable of withstanding rifle bullets), impact resistance (withstanding blast wave pressure ≥100kPa), and light transmittance (≥70%). In terms of fire resistance, it can effectively intercept multiple consecutive shots from handguns (e.g., 9mm bullets with a muzzle velocity of 360m/s) and rifles (e.g., 7.62mm bullets with a muzzle velocity of 830m/s), providing a safe buffer for high-risk locations such as banks and military facilities. Its multi-layered composite structure (typically containing 2-3 layers of polycarbonate interlayer) provides excellent blast resistance, preventing secondary injuries from flying glass shards. It also possesses fire-resistant properties (fire resistance limit of 60-90 minutes), slowing the spread of fire in emergencies.
