Material Notes:
Styrene-Butadiene CopolymerCustomer Benefits: BK11 is an SBC consisting of KR03 grade with a mold release added of easier processing. BK11 molded parts give excellent detail on fast production cycles, and are easily processed by injection molding. This resin can be tinted or colored in a variety of transparent and opaque shades. Compared to KR03, BK11 offers improved mold release with the same injection molding process conditions, and equivalent molded part performance and properties. Molded parts offer excellent clarity, good toughness, good stiffness, and high surface gloss.Applications: Major applications include molded boxes and containers, toys, displays, medical devices, overcaps, and novelties.Processing Recommendations:Injection Molding: Minimum melt temperature between 193-232°C necessary to permit mold fill. Minimum injection pressure required to fill the cavity. Maximum back pressure of 0.3 MPa. Drying: Generally, no need to dry resin.Specification Data: FDA Regulation 21 CFR 177.1640. Suitable for contact with non-fatty foods. [Parts over 0.200 inches thick, for alcoholic beverages, or for high temperature food use (hot filled over 150°F or heat sterilized over 212°F) would require additional testing.Data provided by Chevron Phillips Chemical Company LP.
