Abstract

Thermoplastic elastomer mixture which comprises at least one thermoplastic elastomer TPE, with the exception of a thermoplastic polyurethane TPU, and at least one filler from the group of precipitated silica, or precipitated silicate or carbon black.The thermoplastic elastomer mixtures are produced by, in a first step, mixing at least one filler selected from the group of precipitated silica, or precipitated silicate or carbon black, and at least one thermoplastic to give a masterbatch and, in a second step, mixing the masterbatch with at least one thermoplastic elastomer, with the exception of a thermoplastic polyurethane TPU.The thermoplastic elastomer mixture can be used in injection-molded items.
