INEOS Styrolution K-Resin® KR05 Styrene Butadiene Copolymer (SBC)
Categories: Polymer; Thermoplastic; Styrene-Butadiene; Styrene-Butadiene Copolymer, SBC

Material Notes: K-Resin® KR05 alone or in blends, can be extruded into sheet and thermoformed on conventional equipment at high output rates. The favorable economics of K-Resin® SBC, along with high productivity, have made possible tough clear disposable drinking cups, lids and other packaging applications. INEOS Styrolution has several grades of K-Resin® SBC tailored for your sheet extrusion needs. K-Resin® KR05 will process on most conventional equipment, allowing the molder to run a crystal clear bottle without expensive machine modifications, special molds, different screws, or dryers. K-Resin® SBC are blow molded in a broad range of sizes and shapes, from small pill bottles and medical drainage units, to very tall display bottles. They can also be injection blow molded into extremely high impact bottles with glass-like clarity. Features: Excellent Clarity, Good Stiffness, Good Formability, Good Toughness, High Surface Gloss. Applications: Bottles, Molded Boxes and Containers, Medical Devices, Portion Packages, Blister Packaging
