A polyamide molding compound comprising the following components:
- (A) 40 to 95 wt % of a polyamide mixture consisting of the polyamides (A1) and (A2), wherein
- (A1) 42 to 68 wt % of at least one semi-crystalline polyamide is selected from the group comprising PA 46, PA 66, PA 66/6, PA 610, PA 612, PA 614, PA 615, PA 616, and mixtures thereof;
- and
- (A2) 32-58 wt % of at least one transparent semi-aromatic polyamide having at least 30 mol % of monomers having aromatic structural units, with respect to the total quantity of diamines and dicarboxylic acids is in the polyamide (A2) that is amorphous or microcrystalline;
- (B) 5 to 50 wt % of at least one glass filler having a refractive index in the range from 1.540 to 1.600;
- and
- (C) 0 to 10 wt % of at least one additive;
- wherein the weight proportions of the components (A) to (C) add up to 100% by weight of the component (A) and the weight proportions of the components (A1) and (A2) add up to 100% by weight of component (A);
- wherein the at least one transparent polyamide (A2) has a transparency of at least 90% and a haze of at most 3%.
