GENERAL INFORMATION
This synthetic organic polymer is a member of the polyvinyl acetal family of resins produced commercially though the reaction of polyvinyl alcohol with butyraldehyde. Polyvinyl butyral (PVB) properties including high tensile strength, impact resistance,transparency and elasticity. PVB resins are used in general industrial and wood coatings,wash primers,ceramic substrates,composites and structural adhesive film interlayer in laminated safety glass (LSG) in automobile windshields and architectural safety glass.
