Dupont EVA Elvax 460
Dupont EVA Elvax 460 is an ethylene‑vinyl acetate (EVA) copolymer resin from Dupont’s Elvax family, engineered for demanding industrial applications including flexible packaging films, extrusion, molding, compounding, adhesives, sealants, and wax blends. With 18% vinyl acetate, a melt index of 2.5 g/10 min (190 °C/2.16 kg), and density of 0.941 g/cm³, Dupont EVA Elvax 460 balances flexibility, toughness, and processability for use in multilayer films, hot-melt adhesives, cable compounds, and molded parts. Supplied as natural granules with BHT antioxidant stabilization, it is trusted by Indian converters for reliability and consistent global quality.
Polymer Structure & Key Properties
