Chevron Phillips K-Resin® CK02 Styrene-Butadiene Copolymer, Blow Molding Grade (discontinued **)
Categories:	Polymer; Thermoplastic; Styrene-Butadiene; Styrene-Butadiene Copolymer, SBC
Material Notes:	Styrene-Butadiene Copolymer Customer Benefits: CK02 is a blow molding SBC designed to provide a softer, tougher, more flexible container while retaining the clarity and gloss of bottles produced from KR05. Finished products have low stiffness, excellent clarity, high surface gloss, and excellent toughness. K-Resin provides integral handles and wide mouth containers. Applications: Major applications include squeeze bottles, food containers, medical packaging, and toys. Processing Recommendations: Can be processed on extrusion blow, injection stretch, and injection blow. Extrusion: Recommended maximum melt temperature is 195°C. Injection: Recommended maximum melt temperature, 216°C. High shear and restrictive type screws tend to degrade the melt. Generally no need to dry resin. Specification Data: FDA Regulation 21 CFR 177.1640; suitable for food contact. EEC Directive 90/128/EEC and all its amendments. USP Class VI-50. Data provided by Chevron Phillips Chemical Company LP. Ineos Styrolution acquired the K-Resin® product line from Chevron Phillips Chemical Company in 2016. This grade was previously discontinued.
