Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer widely used as a binder, thickener, emulsifier, and film-forming agent in adhesives, textiles, paper coatings, and pharmaceuticals. It is also employed in detergents, cosmetics, and as a protective colloid in various industrial processes. This versatile polymer is non-toxic, biodegradable, and offers excellent film-forming properties. Polyvinyl alcohol has a CAS number of 9002-89-5 and the molecular formula (C2H4O)n with a repeating unit molecular weight of 44.0526 g/mol. It is typically stored at ambient conditions and carries a signal word of "Warning" per GHS classification. Molekula supplies Polyvinyl alcohol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
