Chevron Phillips EA6765 Rubber Modified Polystyrene (discontinued **)
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Impact Modified
Material Notes:	Description Chevron EA6765 is a general purpose, high impact polystyrene material developed for packaging applications. Its processing characteristics make EA6765 suitable for extrusion and deep-draw thermoforming. This material provides good surface smoothness, moderately high heat distortion and excellent practical toughness. Chevron EA6765 natural complies with Food Additive Regulation 21CFR177.1640 for polystyrene and rubber modified polystyrene, which states that such materials may be safely used in contact with foods. Applications Chevron EA6765 is recommended for such applications as ice cream containers, container lids, cups for hot and cold drinks, conical cup liners and individual portion containers.Information provided by Chevron Phillips Chemical Company. The Chevron Phillips polystyrene product line was transferred to Americas Styrenics in 2008.
