PVB Film is a kind of the laminated glass interlayer, or called PVB interlayer/sheets, it is manufactured commercially by extrusion with PVB resin, plasticizer and additives. PVB film exhibit special characteristics such as transparency, impact resistance, high tensile strength, and elasticity, even if the glass cracks, splinters will adhere to the interlayer and not scatter. These properties make the films and sheets suitable for the manufacture of safety glass. It is primarily used in the production of automotive windshields and the usage of PVB film in building & construction, Additionally PVB film can be applied in photovoltaic modules fields.
