A new styrenic block copolymer from Kraton Polymers, Houston, reportedly offers reduced compression set and improved stress relaxation at temperatures above 70 C (158 F). Molecular weight of Kraton G1633 is 50% higher than that of standard SBCs and its compression-set value approaches that of some olefinic TPVs. Kraton says compression set is further optimized when G1633 is used with certain polyolefin Wends such as a combination of PP and HDPE. Uses include automotive grommets and weather seals and medical stoppers and plunger tips. (800) 457-2866 * www.kraton.com
