In a joint news release, the co-developers, Kraiburg and Lanxess AG said, “with a maximum operating temperature of up to 170°C, Hipex can withstand such temperatures for a period of several days. The polar nature of the two polymer components is the reason why the new TPV also displays exceptional oil resistance
Hipex is based on the Levapren ethylene vinyl acetate (EVM) rubber elastomer from Lanxess, combined with a polar copolyester.
“The two polymer components are perfectly tailored to one another and undergo dynamic vulcanization at Kraiburg TPE using a crosslinking system specially optimized for the job. This produces high-quality TPV pellets with optimized phase morphology,” said Kay Varnhorn, Product Developer at Lanxess.
Kraiburg TPE GmbH & Co. KG is based in Waldkraiburg, Germany. Lanxess is based in Leverkusen. (Plastic News)
