Polyvinyl butyral (PVB) film is a clear, colorless, amorphous thermoplastic obtained by condensation reaction of polyvinyl alcohol and butyraldehyde. The resin is known for its excellent flexibility, film-forming and good adhesion properties as well as outstanding UV resistance.
Use laminated glass can make car more safe and better sound insulation.
