Chevron Phillips MC3700 High Flow Crystal Polystyrene (discontinued **)
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Transparent Grade
Material Notes:	Description Chevron polystyrene resin MC3700 crystal is a free-flowing, crystal clear polystyrene injection molding compound, designed specifically for thin- and medium-walled or long-flow, difficult-to-fill parts of any size or complexity. MC 3700 combines greater processing latitude, exceptional mold release and the overall good molding characteristics required by such parts. MC3700 provides improved cycle times, better part stackability, reduced dusting and fewer part rejects. Processing energy requirements can also be reduced. Chevron MC 3700 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 MC3700 is recommended for such applications as housewares, disposable cups and cutlery.Information provided by Chevron Phillips Chemical Company.
