Ethylene vinyl acetate copolymer, referred to as EVA. Ethylene vinyl acetate (VA) content in 5%-40%, and polyethylene (PE) compared to EVA due to the molecular chain of the vinyl acetate monomer, thereby reducing the high crystallinity, improved toughness, impact resistance, filler compatibility and heat sealing performance, EVA resin is widely used. In general, the vinyl content is below 5% EVA, its main products are film, wire and cable, LDPE modifier, adhesive; vinyl acetate content in 5%~10% EVA products for elastic film; vinyl acetate content in 20~28% EVA, mainly used for hot melt adhesives and coating products; vinyl acetate content in 5%~45% the main products (including film, agricultural film and sheet), injection molding, molding products, foam products, hot melt adhesive etc.. (1) film, sheet and laminated products: sealing, adhesion, flexibility, toughness, tight fit, flexible packaging film, heat shrinkable film, agricultural film, food packaging film, laminated film, can be used in the middle layer of the laminated film made of polyolefin. (2) general products: flexibility, environmental stress, cracking resistance, good climate resistance, suitable for industrial materials, power lines, insulation bags, household electrical appliances parts, window sealing materials, etc.. (3) daily necessities have sporting goods, toys, cushion, drawstring, sealed container cover, EVA rubber, football and so on. (4) auto parts include shock absorbers, fenders, interior and exterior decorative fittings, etc.. (5) foaming products: pressurized foaming, foam plastics, slippers, sandals, building materials, etc.. Injection molding foam has a variety of industrial components, women's soles, hot melt adhesives. Molding process of ethylene vinyl acetate copolymer EVA can be injection molding, extrusion, blow molding, calendering, rotational molding, foam, vacuum coating, heat sealing, welding and other processing.
