Abstract

Described is a thermoplastic molding composition comprising: a) 0.05 to 1.5 wt. %, with respect to the entire molding composition, of a fatty acid amide ester wax; b) 0.5 to 10 wt. %, with respect to the entire molding composition, of a silica selected from natural silica, synthetic silica and mixtures thereof; c) 0 to 1 wt. %, with respect to the entire molding composition, of a montan wax; and d) at least one thermoplastic elastomer. Also described are a method of preparing the thermoplastic molding composition, and methods of preparing articles from the thermoplastic molding composition.
