Chevron Phillips EB6765 Rubber Modified Polystyrene (discontinued **)
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Impact Modified
Material Notes:	Description Chevron EB6765 is a general purpose high impact polystyrene developed for use in packaging applications. Its processing characteristics make EB6765 suitable for extrusion and deep-draw thermoforming. EB6765 has been developed to permit the processing of high levels of regrind. This material provides good surface smoothness, moderately high heat distortion and excellent practical toughness. Chevron EB6765 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 EB6765 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.
