How is Shatterproof Glass Manufactured?

The manufacturing of shatterproof glass involves two primary processes: lamination or tempering.

Laminated Glass: This type of shatterproof glass features two or more layers of glass with a plastic interlayer (often made from polyvinyl butyral or PVB) between them. These layers are fused under heat and pressure. If the glass is struck, the plastic layer holds the shards together, preventing them from scattering.
Tempered Glass: In this process, the glass is heated to extremely high temperatures and then cooled rapidly. This strengthens the outer layers of the glass, making it much more resistant to impacts. If tempered glass breaks, it crumbles into small, blunt pieces that are far less likely to cause injury than regular glass.

Both methods significantly increase the glass’s strength and safety, making it ideal for various applications.
