Description
1) A general name for a family of thermoplastic vinyl resins produced by the condensation of polyvinyl alcohol with an aldehyde. Examples are polyvinyl acetal (Alvar), polyvinyl formal (Formvar®) and polyvinyl butyral (Butvar®). They are used as adhesives, paints, coatings, and films.
2) A specific name for resins made from the condensation of polyvinyl alcohol with acetaldehyde (Alvar). Polyvinyl acetal is a thermoplastic, transparent resin used in lacquers, coating and for phonograph records. It is tough and hard with good adhesion but weathers less well than polyvinyl acetate.
Note: these resins are not the same as acetal resins.
Synonyms and Related Terms
poly(vinyl acetal); polivinilacetal (Esp.); Alvar; Butvar® [Solutia]; Formvar® [Solutia]; Vinylite [Union Carbide];
