Celanese Ateva® 2821A Ethylene Vinyl Acetate Copolymer
Categories:	Polymer; Thermoplastic; Ethylene Vinyl Acetate; Ethylene Vinyl Acetate; Molded/Extruded
Material Notes:	Ateva® 2821A resin is well suited for extrusion coating, co-extrusion and specialty lamination applications. This EVA resin may be safely used as articles or components of articles intended for uses in contact with food as provided in FDA regulation 21 CFR 177.1350 - Ethylene-vinyl acetate copolymers, subject to extraction limitations on the finished food-contact article as specified in that regulation. This polymer may be processed on conventional extrusion equipment. It is recommended that the melt temperature be kept below 210°C as decomposition can occur at higher temperatures. Additives: Antioxidant Applications: Extrusion Coating & Laminating Information provided by Celanese Corporation.
Key Words:	extrusion coating, co-extrusion and specialty lamination applications
