Ethylene-vinyl acetate copolymer

Ethylene-vinyl acetate copolymer (CAS 103470-05-9), also identified by E-number E1050, is a thermoplastic resin used across adhesives, coatings, and packaging applications.

The vinyl acetate content determines flexibility and adhesion characteristics, allowing formulators to select grades precisely matched to processing and end-use requirements.

In hot-melt adhesive formulations, EVA provides the backbone resin for packaging seals, bookbinding, and product assembly lines where fast set times and strong bonds are required.

Flexible packaging films and shrink wraps rely on EVA to deliver softness and heat-seal performance without compromising clarity for the final consumer product.

Coatings and sealant manufacturers incorporate it as a rheology modifier and film-forming agent in waterborne systems to improve the overall durability of the finish.

In the rubber and footwear sector, EVA foam compounds are used for midsoles and cushioning components where controlled density and resilience are critical for performance.

Ethylene-vinyl acetate copolymer is supplied as pellets, granules, and emulsion dispersions depending on the intended processing method and the specific machinery used.

Grades vary primarily by vinyl acetate content, typically ranging from 9% to 40% VA, with higher VA content delivering increased flexibility and tackiness for industrial use.
