Inorganic glass because it has good adhesion, and a transparent, heat, cold, humidity, high mechanical strength properties, manufacturing laminated safety glass is currently the world's best adhesive material. Between two or more layers of glass sandwiched on tough transparent PVB film, made ​​by high temperature high pressure processing on the laminated safety glass. When subjected to a strong external impact, PVB film can absorb impact energy, glass fragments will be firmly adhered to the PVB film and thus will not be scattered, the person may produce harm reduction to a minimum. So this is widely used in automotive safety glass, high-rise buildings, and even marine, aviation and other fields. Now, transparent PVB film has become a very common use of industrial products.
