PVB interlayer film is mainly used in making laminated safety glass. Laminated glass is a special glass which is inserted with PVB film between two layers of common glass, which under high heating temperature and pressure, binds to create a single construction. Because of PVB laminated glass with the function of safety, heat preservation, noise proof, and ultraviolet resistance, etc, it is widely used in areas such as high-rise building and auto. PVB film with special formula is also used in aeroplane, space flight ware, military instrument, solar battery, solar energy acceptor and so on.
