Chevron Phillips EB6755 Rubber Modified Polystyrene  (discontinued **)
Categories: Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Impact Modified

Material Notes: Description

Chevron EB6755 is an extrusion grade, high impact polystyrene developed for use in packaging applications. It is designed for exceptional environmental stress-crack resistance and practical toughness. Chevron EB6755 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 EB6755 is particularly well suited for containers and lids used for packaging stress-crack aggressive food products (yogurt, sour cream, delicatessen salads, dips, etc.) and applications requiring excellent practical toughness such as multiple use lids.Information provided by Chevron Phillips Chemical Company.
