Fresh Polyvinyl Butyral Resin Polyvinyl Butyral Film for safe glass
PVB interlayer 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.
Safety
Due to high tenacity and adhesion of PVB films, the films can endure external impact and are hard to penetrate through. Although the glass might be broken, it reduces the damage level dramatically since the glass fragment will not scattered around.
Energy saving
PVB films can reduce radiations from the sun to penetrate into buildings and automobiles, which can balance the high temperature sunlight. Thus, will save electricity consumption for air-condition in buildings and automobiles effectively.
Sound proof
PVB films have a good characteristic of Sound proof, which not only block external noise from outside but also provide a private space.
Architectural Grade PVB film has wide range usage in the field of architectural glass,such as construction wall,cover grid,show wind,bank counter,screen of steel-smeding furnace and bulletproof glass and so on.
