Chevron Phillips EA3400 Medium Flow Crystal (discontinued **)
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Transparent Grade
Material Notes:	Description Chevron EA3400 is a medium flow-crystal polystyrene resin developed to blend with Styrene-Butadiene block copolymers for sheet extrusion and vacuum thermoforming. EA3400 can be used in cap layer applications. EA3400 should be used in applications where clarity, toughness, and minimal taste/odor transfer is essential. This resin contains less than 250 ppm of residual volatiles. EA3400 complies with Food Additive Regulation 21CFR177.1640 for polystyrene, which states that such materials may be safely used in contact with foods. Information provided by Chevron Phillips Chemical Company. The Chevron Phillips polystyrene product line was transferred to Americas Styrenics in 2008.
