PVB is the abbreviation of Polyvinyl Butyral. In order to meet the demand of glass. S safety and transmittance in defense area, America Defense appointed to develop a new special adhesive material. So people found PVB. PVB is made from PVB resin and plasticizer. It is a non-toxic and smell-free soft sheet material with thickness between 0.2mm-2mm, the best material for the interlayer of safety glass as its wonderful product property such as anti-penetration, anti-ultraviolet, Soundproof etc.
