DuPont EAA-2014 Introduction: AA content = 8%; melt index = 8g / 10min; Vicat softening point = 57 ℃; mainly used in adhesives, coatings applications, laminates, pipe coating and so on. Ethylene acrylic acid copolymer (Ethylene Acrylic Acid Acronym EAA) is a thermoplastic polymer and high adhesion, due to the presence of carboxyl groups as well as hydrogen bond, crystallization of the polymer is suppressed, the linear main chain is damage, thus increasing the transparency and toughness EAA, lower the melting point and the softening point. When MI is the same, with the increase of AA content, EAA transparency, toughness, adhesion, resistance to environmental stress cracking resistance will increase; the contrary, its rigidity, moisture vapor transmission rate, creep resistance, chemical resistance will better. When the AA content of the same, with the increase of MI, EAA adhesion, workability will be better; the contrary, its toughness, resistance to environmental stress cracking resistance will increase. Second, characteristics: 1, excellent adhesion, and can EAA adhesive materials are: aluminum and tin and other metals and oxides, glass, cellulose, wood, leather, cellophane, proteins, nylon, polyurethane, polyethylene EPDM rubber, etc. 2, toughness and flex 3, ease of processing three application areas: EAA is widely used in areas of packaging, powder coatings, adhesives, hot melt adhesives, sealants, solvents, water, Below is a brief description: 1. Packing: extrusion coating production of beverage cartons, toothpaste tubes, cable shielding, etc., while the protective effect EAA also tear, puncture resistance and corrosion; 2, powder coating: EAA powder can sprayed on the surface of the pipe material, steel, non-woven fabrics, etc., as the anti-corrosion materials; 3, hot melt adhesives: high performance and high MI of EAA can produce hot melt adhesive material for difficult; 4, aqueous solvents: high AA content The high MI EAA under appropriate reaction conditions can be dissolved in hot alkaline solution, water-based adhesive may be formulated, for clothing and other fabrics;
