EVA PREMIX Pre-Elec CP 1319Use performance

EVA (ethylene - vinyl acetate copolymer), Characteristics and Uses:
A. Characteristic
EVA resin is characterized by having a good softness, rubber-like elasticity, at -50 ℃ still be able to have a better flexibility, and transparency and surface gloss, good chemical stability, aging and ozone resistance strength Good, non-toxic. Good miscibility with fillers, coloring, and moldability is good.
And vinyl acetate content and molecular weight, melt index relationship. When the melt index (MI) is constant, the content of vinyl acetate (VAC) to improve its flexibility, softness, compatibility, transparency, etc. also rise. VAC content reduction, the performance is close polyethylene, the rigidity increased, increased wear resistance, electrical insulating properties. If the VAC content is a certain time, when the melt index increases, the softening point depressants, workability and surface gloss to improve but the intensity will drop, Otherwise, with the MI of reducing the molecular weight increases, the impact properties, and the performance improvement of environmental stress cracking resistance.
Titanium root polarity so that the elasticity and viscosity increases, the crystallinity and electrical properties, soluble in hydrocarbon solvents and oils.
II. Use
EVA resin very versatile. Under normal circumstances, the vinyl acetate content of 5% or less EVA, its main product is a film, wire and cable, LDPE modifiers, adhesives, etc.; elastic membrane, etc. of the vinyl acetate content of 5% to 10% of the EVA product; vinyl acetate content of 20 to 28% of the EVA, is mainly used for hot melt adhesive and coating products; vinyl acetate content of 5% to 45%, the main products for the film (including agricultural film) and sheet, injection moldings , foam products, hot melt adhesives. Such as:
(1) films, sheets and laminates: sealability, adhesion, flexibility, toughness, and tightening, suitable for flexible packaging film, shrink film, agricultural film, food packaging films, laminated film, can be used on doing the intermediate layer of the polyolefin laminate film.
(2) General supplies: flexibility, resistance to environmental stress cracking resistance, weather resistance good advantage, suitable for industrial power wire insulation material purses and accessories for electrical appliances, window sealing material.
(3) groceries class sporting goods, toys, cushions, belted, sealed container cover, EVA rubber football.
(4) auto parts shock absorbers, fenders, car interior and exterior decoration and other accessories.
(5) foam products: pressurized foam foam slippers, sandals, building materials and so on. Injection foam has a variety of industrial parts, female soles, hot melt adhesive.
EVA can be injection molding, extrusion molding, blow molding, calendering, rotomolding vacuum thermal molding, the molding of the foam, coating, sealing, welding or the like.
