Ethylene Methacrylic Acid (EMAA)

Ethylene Methacrylic Acid Copolymers (EMAA) are produced by reacting ethylene with methacrylic acid. The ethylene segments provide properties such as water resistance, flexibility, chemical resistance and flexibility. The presence of methacrylic acid brings polarity, adhesion, toughness, hot tack strength and low temperature heat sealability. Increasing the methacrylic acid content increases the adhesion to polar substrates, reduces the softening and melting temperatures, improves clarity and increases strength. Methacrylic acid copolymers are heavily used in flexible packaging such as laminated tubes, condiment pouches and sachets, aseptic packaging, meat and cheese packaging, as well as protective metal coating, wire and cable and powder coating. Methacrylic acid copolymer have also found use in aqueous dispersions, glass adhesives, and ink and paint formulations.
