Ethylene vinyl acetate (EVA)
ELEVATE® Ethylene Vinyl Acetate (EVA) Copolymers are thermoplastic materials produced by the copolymerization of ethylene with vinyl acetate monomer in a high-pressure reactor. Westlake specializes in EVA formulation with vinyl acetate content up to 18%, appropriate for use in thermoplastic extrusion, film compounds and foam molding. With softness and flexibility approaching elastomeric materials, EVA has good clarity and gloss, barrier properties, low-temperature toughness, stress crack resistance and ultraviolet (UV) resistance. Applications include a wide variety of end-uses, such as flexible packaging, heat seal layers, thermal laminations, hose and tubing, blow molded (soft touch) bottles, cap liners, and foam which is used for shoe soles.
