Blending KRATON D and G polymers with PE significantly improves the toughness at both room and low temperatures. KRATON polymers are block segments of styrene and rubber monomers (A-B, A-B-A, or [A-B]n). The KRATON D series consists of an unsaturated polymer, either butadiene or isoprene, as the rubber monomer. Unless otherwise specified, All properties listed below are measured on blown film, 4 mil (100 microns) thick. Information provided by the manufacturer, Kraton® Polymers. |
