Kraton® G1657 + PP blend + Talc (12/21/67)

Unmodified polypropylene has high rigidity and good heat resistance, but poor impact resistance, especially at low temperatures. Blending KRATON D and G polymers with PP 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 G series are second generation block polymers in which the rubber monomer is a saturated olefin polymer, either ethylene/butylene or ethylene/propylene. Kraton G polymer grades manufactured in France are labeled with an "E" for standard grades and "ES" for grades dusted with silica, for distribution in Europe, Africa and Asia Pacific.
