A mixture comprising at least one polymer and from 0.1 wt % to 1.5 wt %, based on the weight of the polymer, of at least one fumed silica, wherein the polymer comprises at least one semi-aromatic polyamide in an amount of more than 50 wt %, based on the weight of the polymer. The presence of the fumed silica in the semi-aromatic polyamide-based mixture allows notably for reducing the cycle time necessary for the manufacture of various shaped articles, such as mobile phone housings, by melt processing methods like injection molding. |
