EAA 5000 is mainly used for extrusion coating, extrusion coating and extrusion lamination. EAA 5000 Advantages and Uses: good adhesion to polar substrates, aluminum foil, metal film, paper, steel and glass surfaces. Provide adhesion to the substrate surface and a coextruded low density polyethylene and ethylene vinyl acetate interlayer bonding force ester film excellent excellent balance of adhesion polymer. EAA 5000 Physical indicators: melt flow rate (190 ° C / 2.16 kg) 8.2 g / 10 min acid content 6.0 wt% EAA profile: ethylene - acrylic acid copolymer, and a thermoplastic material having a high cohesiveness. When MI is the same, with the increase of AA content of transparency, toughness, adhesion property and the resistance to environmental stress cracking resistance will increase; contrary rigidity, steam transmissivity, chemical resistance is better. When the AA content of the same, with the MI increases adhesion, processing performance will be better. Mainly used in packaging, powder coatings, adhesives, hot melt adhesives, sealing materials, water-based solvents, environmentally degradable materials. Physicochemical Principle: 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 main chain linearity is destroyed, thereby increasing the EAA transparency and toughness, lower the melting point and the softening point.
