An Ultra High Molecular Weight SEBS Polymer for High Temperature TPE Applications

Abstract

Many automotive and medical TPE applications require good balance of high temperature performance and processability. Conventional styrene-ethylene-butylene-styrene (SEBS) block copolymers are limited in performance at higher service temperatures. Ultra-high molecular weight SEBS can be used to achieve low compression set at high temperatures and a wider range of hardness in compounds, as well as compatibility with TPV. This presentation compares properties and processability of various compounds based on a conventional SEBS polymer, an ultra-high molecular weight SEBS polymer, and blends with TPV compounds.
