EVA plastic name: ethylene - vinyl acetate English name: Ethylene-vinyl acetate copolymer English Name: Poly (ethylene-co-vinyl acetate) ethylene - vinyl acetate copolymer referred to as EVA, typically vinyl acetate (VA) containing 5% 40%. Compared with polyethylene, EVA [1] Since the introduction of the molecular chain of vinyl acetate monomer, which reduces the high crystallinity, improved flexibility, impact resistance, and thermal compatibility packing sealing performance, are widely used Foam shoe materials, functional films, packaging films, adhesives, wire and cable and toys and other fields. EVA resins are characterized by good flexibility, rubber-like elastic, despite the -50 ℃ to have good flexibility, transparency and surface gloss, good chemical stability, anti-aging and ozone resistance strength good, non-toxic. Mixing with the filler is good, good coloring and forming. EVA resin is widely used. In general, vinyl acetate content of 5% or less of the EVA, its main products are thin film, wire and cable, LDPE modifier, adhesive, etc.; vinyl acetate content of 5% to 10% of the EVA film and other flexible products; acetate content of 20 ~ 28% of EVA, is mainly used for hot-melt adhesives and coating products; vinyl acetate content of 5% to 45%, the main products for film (including agricultural film) and sheets, injection molding, molded products, foam products, hot melt adhesives. Such as: (1) films, sheets and laminated products: a seal, adhesion, flexibility, strength and toughness, tight, suitable for flexible packaging film, shrink film, agricultural film, food packaging films, laminated films, polyolefin laminated film can be used to make the middle layer. (2) General supplies: a flexible, anti-environmental stress cracking resistance, and good climate advantages for industrial use of electric wire insulation material bags, household accessories, window sealing materials. (3), groceries class of sporting goods, toys, cushions, straps, sealed container lid, EVA rubber football. (4) auto parts are shock absorbers, fenders, car accessories, such as internal and external decoration. (5) foam products: foamed with pressurized foam slippers, sandals and construction materials. Foam injection molding a variety of industrial parts, female soles, hot melt adhesives. Ethylene - vinyl acetate copolymer EVA can be injection molding process, extrusion, blow molding, calendering, rotational vacuum thermoforming, foaming, coating, sealing, welding, forming. Ethylene - vinyl acetate copolymer (EVA) EVA resin, ethylene - vinyl acetate copolymer, vinyl acetate generally (VA) content of 5% to 40%. Compared with polyethylene, EVA molecular chain due to the introduction of vinyl acetate monomer, which reduces the high crystallinity, improved flexibility, impact resistance, and thermal compatibility packing sealing performance, are widely used in foam shoes materials, functional films, packaging films, adhesives, wire and cable and toys and other fields.
