The automotive laminated glass PVB film is widely used in cars, buses, high-speed rail, its versatility not only has anti-penetration and anti-splash and other safety performance and it can play comfort, security, and other effects. And on this basis it can further improve the added value, with a quiet space to maintain the sound insulation and it can inhibit the internal temperature of the heat insulation and so on.
