ExxonMobil Escor™ 5050 Ethylene Acrylic Acid Copolymer Resin
Categories: Polymer; Thermoplastic; Ethylene Acrylic Acid

Material Notes: Ethylene and acrylic acid (EAA) copolymer resins offer excellent adhesion to polar substrates without the need for primers. Applications include liquid aseptic, dry-food and laminated tube container packaging, and cable shielding.  Benefits: Adhesion to a range of polar substrates including metalized films, papers, iron, steel and glass, Balance of adhesion onto the substrates and inter layer adhesion with coextruded LDPE and EVAs, Formulations can be UV-stabilized for use in outdoor applications, High bond resistance when used to pack acidic food products, Coextrusion adhesive resin for polyamides, Sealing performance: very low temperature sealing with high seal strengths, high hot-tack forces and good seal-through contamination.  Escor™ 5050 resin is primarily intended for extrusion coating, coextrusion coating, and extrusion lamination.  It has very good adhesion to polar substrates, aluminum foil, metalized films, paper, iron, steel, and glass.  It offers excellent balance of adhesion onto substrates and inter layer adhesion with coextruded LDPE and EVA material. 

Availability:  Africa & Middle East, Asia Pacific, Europe, North America. 

Additive:  antiblock: no, slip: no; thermal stabilizer: no. 

Applications:  Aluminum containing packaging, extrusion coating, liquid packaging, cable shielding, food packaging, Extrusion lamination, metalized films, coextrusion coating, hygiene packaging, cosmetic packaging.
