What is laminated safety glass composed of?

Laminated safety glass is designed for enhanced strength and safety, particularly in automotive applications. It consists of two sheets of plate glass that are bonded together using a layer of tough plastic, typically polyvinyl butyral (PVB). This configuration is what makes laminated glass effective at holding together when shattered, reducing the risk of injury from flying glass shards and providing a barrier against external elements.

The combination of the glass and plastic layer allows the glass to maintain its integrity even under impact, making it less likely to break apart completely. This property is crucial for safety in vehicles, as it helps protect passengers and keeps the structural integrity of the windshield intact during collisions or accidents. Thus, the composition of laminated safety glass plays a vital role in both safety and structural performance.
