Styrene-Butadiene Copolymer. Properties below based on 1 mil ( 0.025 mm) film; 2.5:1 Blow Up Ratio; 35 mil (0.90 mm) die gap. Customer Benefits: Provides the same high performance film properties as KR10 with added thermal stability and a broader processing window. Film produced has excellent clarity, high surface gloss, good heat sealability, good toughness, good stiffness, and high permeation. Has a puncture value of 1.2 J as per ASTM D3763. Has a crease retention of 99% as per TAPPI T446-B. Also has a moisture vapor transmission value of 0.6 g mm/m^2 24hr as per ASTM F1249 at 23°C. Film shrinkage is 67% MD and 48% TD. Applications: Major applications include medical packaging, produce packaging, skin packaging, twist wrap, lidstock film, labeling film, decorative films, industrial films, shrink wrap, overwrap film, barrier film, and tamper evident packaging Processing Recommendations: Blown Film: Melt temperature between 166-193°C recommended. Cast film: Melt temperature between 193-216°C recommended. High shear and restrictive type screws tend to degrade the melt. 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. Ineos Styrolution acquired the K-Resin® product line from Chevron Phillips Chemical Company in 2016. |
