What is PVB Interlayer?

About PVB laminated glass

Laminated glass is a type of safety glass that provides enhanced shatterproof performance. The interlayer film consisting of PVB (polyvinyl butyral) as the main raw material is laminated between two sheets of glasses at high temperature and pressured by an autoclave to mainly prevent the glass from shattering.
Laminated glass is applied on multiple applications such as automotive windshields, windows, roofs and architectural glass.
