Elvax 670 Ethylene-vinyl acetate copolymer DuPont Ethylene co-terpolymers - solid (EVA, EMA) >> Ethylene Vinyl Acetate, EVA Elvax(R) is the DuPont registered trademark for a broad line of ethylene-vinyl acetate copolymer resins for use in adhesives, sealants, and coatings. Elvax(R) blended with a petroleum wax and resin tackifier is the basis of many hot melt adhesives. In addition, Elvax(R) resins impart plastic-like properties that enable wax to compete effectively with high-quality polymeric coatings. In summary, Elvax(R) resins are key ingredients in a variety of hot melt and solvent-applied systems. They are used as: Resin bases for flexible, heat-sealable, hot melt coatings with excellent water vapor and gas barrier properties. 500, 600, and 700 Series Resins (<18% VA) may be used in hot melt systems where their low cost makes them attractive extenders or modifiers. Resins in this series may also impart higher temperature resistance where this property is required. These same resins are used for molding, compounding, and extrusion applications. All grades contain 190-910 ppm butylated hydroxy toluene. Ethylene-vinyl acetate copolymer resin. Contains butylated hydroxytoluene. Used as a resin base for flexible, heat-sealable, hot melt coatings. Provides very good water vapor and gas barrier properties, toughness, flexibility, and adhesion. Can be used as an extender and modifier. Gives high temperature resistance.
