Ethylene acrylic acid copolymer is a carboxyl group containing copolymer generated by high-pressure and high-temperature free radical polymerization of ethylene and acrylic acid, with a density of 0.932g/cm ³. Its melting point, rigidity, and yield tensile strength are lower than polyethylene. Its gas permeability and resistance to environmental stress cracking increase with the increase of acrylic acid content, and it has transparency, wear resistance, and adhesion. Mainly used in the fields of film packaging and coating adhesives, it can bond rubber, plastic, metal, and glass, and is used to manufacture composite films, wire and cable sheaths, protective clothing, and carpet linings. The ethylene acrylic acid copolymer modified by grafting diamine maleic nitrile and oximation treatment forms a multi-layer porous structure, with an adsorption capacity of 3.196 mg/g for uranyl ions at pH 4 and an adsorption selectivity 8.17 times that of Ba ² ⁺.

PRODUCT FEATURES

Its melting point, rigidity, and yield tensile strength are lower than polyethylene, but decrease with increasing content of alpha and alpha. Its gas permeability and resistance to environmental stress cracking increase with increasing content of alpha. It is transparent, wear-resistant, and has good low-temperature resistance, adhesion, and coloring properties. It is made by high-pressure and high-temperature free radical polymerization of ethylene and acrylic acid. It is used as a film packaging and coating, and as a rubber drill to bond rubber, plastic, metal, and glass. Make composite films, toothpaste tubes, wire and cable sheaths, protective clothing, large antennas, explosion-proof glass, carpet backing, etc.
