    Ethylene vinyl acetate copolymer (EVA) is a thermoplastic resin obtained by copolymerization of ethylene and vinyl acetate. With the increase of vinyl acetate (VA) content, the elasticity, softness, adhesion, compatibility, transparency and solubility of EVA resin are also improved accordingly. Generally, the content of vinyl acetate (VA) is 5% to 40%.

    Compared with polyethylene, due to the introduction of vinyl acetate monomer in the molecular chain, EVA resin has reduced its high crystallinity and improved flexibility, impact resistance, filler compatibility and heat sealing. Therefore, EVA resin granules are widely used in foamed shoe materials, functional shed films, packaging films, hot melt adhesives, wires and cables, and toys and other fields.

    In general, if the VA content is 5% to 15%: agricultural film, heat shrinkable film, various composite films, cable sheathing. The VA content is 15%-40%: shoe soles, sealing strips, foam plastics, hot-melt adhesives, packaging materials; When the VA content is 40%-50%: cable industry. If the VA content is 70% to 95%: coatings, adhesives and coatings for paper and fabrics.

    Film. EVA resin is widely used in film manufacturing due to its high transparency, as well as high impact resistance, tear resistance, low temperature and weather resistance. Such as agricultural film, cast film, deep frozen film, stretch film,laminated film, hot melt film. Due to its unique non-toxicity, it can be used to make food packaging films, medical films and utensils.

    Hot melt adhesive. EVA resin is mixed with tackifying resin and wax to make hot-melt adhesive, which has excellent adhesive force and is widely used in packaging, bookbinding, woodworking, shoe industry, plastic bonding, etc.

    Injection molded products. Making hollow containers, shock absorbers, sound insulation boards, fenders, floor mats, cushions for beer bottles, oil drums and plastic container covers, toilet covers, washing machine sealing plugs, and sealing rings. Bicycle saddles, toys, protective hats, ski shields, safety belts, hard hats, etc.

    Foam. Due to EVA resin has good foaming performance, and it has excellent resilience, aging resistance and crack resistance, it is widely used in shoe soles, foam sheets for insoles and other foams such as baby wheels, various Foamed items for packaging, building and pipeline insulation, sound insulation panels, auto parts, durable belts, gymnastics mats, yacht protection spanners, etc.

    Extruded products

    •  Water pipes, micro-irrigation pipes, mine underground pipes and other hoses.
    • Wire and cable materials (sheath, inner and outer shielding materials, semiconductor materials, heat shrinkable materials, etc.).
    • Various sheets, modified PVC materials for building doors and windows, pipes, and modification of SBS and other materials to improve the weather resistance, elasticity and aging resistance of materials.
    • Besides, EVA resin has good stress crack resistance, it can be used in the manufacture of deep buried pipes.

    Others. The EVA copolymer can also be used as hot-melt coatings, anti-corrosion coatings, and as base materials for inks, paints, and more.

    • The characteristics of EVA have good softness, rubber-like elasticity, good flexibility at -50°C, transparency and surface gloss, good chemical stability, good anti-aging and ozone resistance, and non-toxic . Good blendability, colorability and molding processability with fillers. When the melt index (MI) is constant and the content of vinyl acetate (VAC) increases, its elasticity, softness, compatibility, and transparency will also increase.
    • When the VAC content decreases, the performance is close to that of polyethylene, the rigidity is increased, and the wear resistance and electrical insulation are improved. If the VAC content is constant and the melt index increases, the softening point will decrease, the processability and surface gloss will improve but the strength will decrease, otherwise, the molecular weight will increase with the decrease of MI, and the impact performance and environmental stress cracking resistance will increase.
    • EVA can be processed by injection molding, extrusion molding, blow molding, calendaring, rotational vacuum thermoforming, foaming, coating, heat sealing, welding, etc.
