Chevron Phillips K-Resin® KK38 Styrene-Butadiene Copolymer, Sheet Grade  (discontinued **)
Categories: Polymer; Thermoplastic; Styrene-Butadiene; Styrene-Butadiene Copolymer, SBC

Material Notes: KK38 is an improved extrusion grade SBC designed specifically for superior performance in blends with general purpose polystyrene. It is easily processed by extrusion and gives thermoformed parts with excellent detail on fast production cycles. Thermoformed parts have greater polystyrene acceptance with equivalent processability, very good clarity, excellent toughness, and good stiffness.

Applications: Major applications include thermoformed blister packs, cups and lids, and portion packages.

Processing Recommendations:
Melt Temperature: 216°C maximum. High shear and restrictive type screws tend to degrade the melt. Generally no need to dry resin.

Specification Data: When combined with at least 17% food grade polystyrene to produce articles for food contact, KK38 complies with FDA Regulation 21 CFR 177.1640. EEC Directive 90/128/EEC and all its amendments. USP Class VI-50. UL94HB.

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.
