How Automotive Glass Works?


Material:Laminated glass and PVB

Laminated glass is made by sandwiching a layer of polyvinyl brutality (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 [source: Reuters]. Laminated glass can break and be punctured, but it will stay intact because of its chemical bond with the PVB.

Laminated glass is strong enough to keep flying objects from penetrating a car's windshield.After the laminated glass breakage will be the core of the collision point of radiation, the driver's line of sight is not completely blocked, and the glass can also maintain a whole, to prevent splashing out to hurt people. 

In addition, the replacement of the front windshield, we must pay attention to quality, don't use low price but inferior glass.
