polyvinyl butyral sheet, also called PVB sheet, are extruded mixture of special plasticizer, additives and PVB resin that form PVB films with even thickness.
PVB sheet are primarily applied in laminated glass that is a construction of two or more pieces of glass. The high adhesive PVB films are clamped between layers, so PVB films must equip with excellent adhesion, light transmission and safety.
