  • Polyvinyl butyral (or PVB) is a resin usually used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility.
  • It is prepared from polyvinyl alcohol by reaction with butyraldehyde. The major application is laminated safety glass for automobile windshields.
  • Tradenames for PVB-films include GlasNovations, Butacite, Saflex, S-Lec, and Trosifol.
  • In the structure of PVB resin, there are three functional groups: butyral, hydroxyl and acetyl group.
  • Polyvinyl acetates with different molecular weights serve as the starting materials for the production of Mowital.
  • Polyvinyl alcohols (PVA) are produced from polyvinyl acetates via transesterification. The reaction of the aqueous polyvinyl alcohol solution with butyraldehyde in the presence of small amounts of mineral acid yields polyvinyl butyral.
  • PVB is compatible with phthalate ester, phosphate ester, fatty ester, glycol derivatives and many other plasticizers.
  • The thermoforming and coating characteristics of PVB are excellent. And, combining with plasticizers and other resins can further modify its performance .
  • The best-known PVB resin application for metal paints is "wash primer". It is widely used on a variety of metal surfaces, such as storage tank, ship, airplane, bridge, dam lock, electronic appliances and etc.
  • PVB is a 80-year-old product. It has been the dominant interlayer material since the late 1930s. It is currently manufactured and marketed by a number of companies worldwide, including DuPont (Wilmington, Delaware, USA) ("Butacite"-brand PVB), Solutia (St. Louis, Missouri, USA) (Saflex-brand PVB), Kuraray Europe GmbH (Frankfurt, Germany) ("Trosifol"-brand PVB and "Mowital / Pioloform" for powdered PVB resins), and Sekisui (Kyoto, Japan) ("S-Lec" brand PVB film and powdered PVB resins).
  • The market for laminated glass products is a mature one, and relatively stagnant. With only minor modifications, the PVB interlayer sold today is essentially identical to the PVB sold 30 years ago.
  • Since its introduction in 1938, the worldwide market for PVB interlayer has been dominated by a handful of large chemical concerns.
