0.76mm Blue on Clear Automotive Windshield PVB Film

Laminated glass is made by sandwiching a layer of polyvinyl butyral (PVB) between two pieces of glass. The glass and the PVB are sealed by a series of pressure rollers and then heated. This combination of pressure and heat chemically and mechanically bonds the PVB to the glass. The mechanical bond occurs through the adhesiveness of the PVB, while the chemical bond is created through hydrogen bonding of the PVB to the glass.

That inserted layer of PVB is what allows the glass to absorb energy during an impact and gives the glass resistance to penetration from flying projectiles. It also deflects up to 95 percent of ultraviolet (UV) rays from the sun. Laminated glass can break and be punctured, but it will stay intact because of its chemical bond with the PVB.
