THERMOPLASTIC ELASTOMER MIXTURES

摘要

Thermoplastic elastomer mixture comprises: at least one thermoplastic elastomer except thermoplastic polyurethane; and at least one filler comprising precipitated silicic acid, precipitated silicate or carbon black. Independent claims are also included for: (1) producing the thermoplastic elastomer mixture, comprising (a) mixing at least one filler and at least one thermoplastic into a master batch, and (b) mixing the master batch with at least one thermoplastic elastomer except the thermoplastic polyurethane; (2) improving the isotropic mechanical properties of injection molded articles, comprising (a) and (b); and (3) an injection molded article comprising the thermoplastic elastomer mixture, where the anisotropy factor is improved with respect to an injection molded article prepared with the above method and above composition, where the filler comprises fumed silica.
