Laminated glass can be produced in two ways: one is to place a PVB interlayer between two layers of glass; One method is to inject resin between two layers of glass. But the built-in interlayer of both methods is a crucial part of laminated glass.
The PVB sandwich method is to sandwich a special tough and elastic material between two layers of glass, and then use high temperature and high pressure to permanently bond them together. Generally speaking, the PVB interlayer is 0.38 millimeters thick, and for automobiles and other special purposes, it can be 0.76 millimeters thick.
The resin casting method involves pouring liquid resin between two layers of glass plates, and then curing them using ultraviolet radiation or other catalytic effects. Products made using this method can achieve diverse product designs while retaining the advantages of laminated glass. So this pouring method is mostly used for the production of irregularly sized laminated glass. This resin can be used for laminating glass and plastic, plastic and plastic, unlike PVB which can only be used for laminating glass and glass. Liquid resin is mostly used for internal areas, and safety is its second important characteristic.
