Abstract:
1. A filled polyamide (PA) molding compound comprising A) 25-72% by weight of a polymer mixture forming a polyamide matrix containing A1) 55 to 90% by weight of an aliphatic polyamide selected from the group PA6, PA46, PA66, PA610, PA612, PA6/12, PA1010, PA11, PA12, PA1012, PA1212 and/or mixtures and/or copolyamide of these, the aliphatic polyamide having a solution viscosity η A2) 10 to 45% by weight of at least one polyamide selected from MACM10-18, MACMI, MACMT, PACM10-18, 6I/6T, the molar ratio of 6I to 6T units being in the range of 40:60 to 25:75, 6T/66, the molar ratio of 6T and 66 units being in the range of 50:50 to 70:30, and/or mixtures and/or copolyamides of these, the polyamide having a solution viscosity η B) 20 to 55% by weight of a glass fiber with a non-circular cross-sectional area and a dimensional ratio of the main cross-sectional axis to the subsidiary cross-sectional axis of 2 to 8, and also C) 8 -25% by weight of a flameproofing agent containing C1) 60 -100% by weight of at least one of a phosphinic acid salt and a diphosphinic acid salt, C2) 0-40% by weight of a melamine polyphosphate.
