Leverkusen - Hipex, a TPV from Kraiburg TPE has unusually high heat and oil resistance. In a joint press release, the co-developers, Kraiburg and Lanxess 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. Other TPEs intended for similar purposes can only achieve these properties at hardnesses of over Shore A 90. In contrast, the range of hardnesses covered by Hipex is very similar to that of rubber. "
Hipex is a TPV (thermoplastic vulcanisates) 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 vulcanisation at Kraiburg TPE using a crosslinking system specially optimised for the job. This produces high-quality TPV pellets with optimised phase morphology," said Kay Varnhorn, Product Developer at Lanxess.
