Ethylene Vinyl Acetate (EVA) is a thermoplastic elastomer formed by copolymerizing ethylene and vinyl acetate (VAc). Its properties vary with VAc content—lower content results in plastic-like characteristics, while higher content brings more rubber-like elasticity. EVA is widely used in injection molding, extrusion, and foam applications such as shoe soles, cable insulation, and packaging films. It improves flexibility, toughness, and compatibility when blended with PE or PP and can be modified for enhanced wear and tear resistance.
