HS Code: 700721 – Laminated safety glass, of size and shape suitable for incorporation in motor vehicles, aircraft …
Laminated glass is produced by combining two or more sheets of float/tempered glass with one or more interlayers and is processed by autoclaving at 1400°C and pressure up to 14 bar. Polyvinyl butyral (PVB) is the most common interlayer used in laminated glass.
The PVB sheet bonds with both the layers of the glass and keep it intact even upon impact. The bond between PVB sheet and glass is a chemical bond and thus it does not delaminate easily.
The glasses used in a laminated glass may be float glass or tinted glass. The layers of glass and PVB sheet can be increased according to the requirement to increase its strength.
One of the biggest benefits of laminated glass is that if it does break, the broken glass will stick to the plastic rather than falling to the floor.
In addition to being found in vehicles, laminated glass is also commonly used for the windows of tall buildings, skylights, balconies, and frameless glass railings
