thick 0.76mm shade blue on clear PVB interlayer film for auto windshield glass
Saflayer PVB interlayer film is a macromolecule material which produced by extrusion using PVB resin, plasticizer and additives. Saflayer pvb film is not only can shield out the UV, heat and sound, but also famous for its high visible transmittance, super anti-penetration. The major application of PVB film is laminated safety glass used on automotive windshields, architectural glass as well as the bullet proof glass.
