Material Notes:
Styrene-Butadiene CopolymerCustomer Benefits: This SBC is easily processed on blow molding or extrusion and thermoforming equipment. Finished products have excellent clarity, good toughness, good stiffness, high surface gloss, good formability. KR05NW is the no wax form of KR05 to facilitate printing and decorating.Applications: Major applications include bottles, profiles, displays, containers, and unblended sheet.Processing Recommendations:Sheet Extrusion: Melt Temperature, 218°C maximum. High shear and restrictive type screws tend to degrade the melt. Generally no need to dry resin. Blow Molding: 188-196°C for maximum melt strength. Generally no need to dry resin. Injection Blow Molding: Melt Temperature, 232°C maximum. 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. UL 94HB.Data provided by Chevron Phillips Chemical Company LP.
