The laminated glass is two-piece of either two-piece of above glass shrinks the butyric baldheaded with one or the multilayered polyvinyl alcohol is thin (PVB) the process pressurizes and heats up the combination becomes. Because in the glass clamps the PVB thin film refractive index extremely approaches glass itself, therefore the laminated glass may maintain and the simple glass it is pure and is transparent.
The laminated glass is one kind of security glass, when glass broken after, its fragment still agglutinated on the PVB thin film, was allowed to prevent the accident the occurrence could resist the penetration which the accident hit, was allowed to guard against theft, to guard against the violence invasion bulletproof, When glass broken after, still agglutinated on the PVB thin film, could not fall; The sound insulated performance is good. May the widespread application to each kind of window and the roof louver window; Window and so on vehicles and ships; Demonstrates the window and the demonstration frame; Other have bulletproof, defends against riots the request special occasion
