PVB film is a semi-transparent film, with good adhesion to inorganic glass, transparent, heat-resistant, cold-resistant, high mechanical strength, it is the best adhesive material for manufacturing laminated glass.PVB film can absorb the impact energy and does not produce broken fragments, this kind of safety glass is widely used in automobiles, high-rise buildings, bank counters, all kinds of bullet-proof glass, etc. With safety performance, it also has excellent sound insulation, light control, heat insulation, shockproof and other properties. In addition to safety performance, there are excellent sound insulation, light control, thermal insulation, heat insulation, shockproof performance, is the world’s ideal safety glass processing materials.
Main applications of PVB film: PVB film for automobile safety glass, the middle layer of automobile windscreen, the middle layer of high-rise building glass, and the encapsulation film for solar thin film battery.
PVB film production line is divided into two practices, one is the dry process, also known as over-roll process, through the calendering extrusion, air cooling and shaping roll, the other is the wet process, also known as over-water process, calendering extrusion of film through the water tank cooling and shaping, followed by blow-drying and winding, the two processes there is a great deal of difference between the equipment, the price also varies greatly.
