Ethylene-vinyl acetate copolymer

Ethylene-vinyl acetate copolymer (CAS 103470-05-9), also identified by E-number E1050, is a thermoplastic resin.

Where is Ethylene-vinyl acetate copolymer used?

• Hot-melt adhesives: backbone resin for packaging seals, bookbinding, and product assembly lines
• Flexible packaging: softness and heat-seal performance in films and shrink wraps
• Coatings and sealants: rheology modifier and film-forming agent in waterborne systems
• Rubber and footwear: foam compounds for midsoles and cushioning components
• Vinyl acetate content determines flexibility and adhesion, letting formulators select grades matched to processing and end-use requirements.

Good to know: Grades vary primarily by vinyl acetate content, typically ranging from 9% to 40% VA; higher VA content delivers increased flexibility and tackiness.
