The resin known as polyvinyl butyral (or PVB) is frequently used in applications that need flexibility, toughness, optical clarity, strong binding, and adhesion to a variety of surfaces. By reacting polyvinyl alcohol and butyraldehyde, it is made. Laminated safety glass for car windscreens is the main use. KB PVB, Saflex, GlasNovations, Butacite, WINLITE, S-Lec, Trosifol, and EVERLAM are some brand names for PVB-films. A stronger and more heat-resistant filament for 3D printers than polylactic acid is PVB. It consists of two glass panels that are joined together by a protective interlayer, often made of polyvinyl butyral. It is frequently used in the automotive and architectural industries. Pressure and heat are applied during the bonding process.
