Polyvinyl acetate

Polyvinyl acetate (CAS 9003-20-7), commonly abbreviated as PVAc and listed as E1519 in food contact applications, is a synthetic polymer produced by the emulsion or bulk polymerization of vinyl acetate monomer.

Where is Polyvinyl acetate used?

• Woodworking and construction: primary binder in white wood glues
• Paper and packaging: laminating adhesive and coating binder for multi-layer board constructions
• Textile and nonwoven: fabric stiffeners and fiber-bonding agents in finishing operations
• Printing: pigment binder in water-based inks and overprint varnishes
• It functions as a film-forming binder and adhesive base in industrial and consumer formulations.

Commercial specifications

• Aqueous emulsion, typically 50–55% solids content
• Solid form as beads or powder for solvent-based applications
• Grades: general-purpose, high-viscosity, plasticized variants
• Food-contact compliance governed by EU and FDA frameworks
