Patent ID: 8586662

Claim:
A filled polyamide (PA) moulding compound made of A) 30-80% by weight of a polyamide matrix containing polyamides A1 and A2: A1) 55 to 85% by weight, of the total weight of A1 and A2, an aliphatic polyamide selected from the group consisting of PA6, PA46, PA66, PA610, PA612, PA6/12, PA1010, PA11, PAl2, PA1012, PA1212, mixtures thereof and copolyamides thereof, and A2) (a) 15 to 45% by weight, of the total weight of A1 and A2, a polyamide selected from the group consisting of MACM10-18, PACM10-18, MCMI, MCMT, MXDI, MXD6, 6I, 6T, and mixtures thereof, (b) 15 to 45% by weight, of the total weight of A1 and A2, at least one copolyamide comprising (i) one or more polyamide units selected from the group consisting of MACM10-18, PACM10-18, MACMI, MACMT, MXDI, MXD6, 6I, and 6T, and (ii) one or more polyamide units selected from the group consisting of PA66, PA610, PA6 and PA12, or (c) 15 to 45% by weight, of the total weight of A1 and A2, a copolyamide selected from the group consisting of MXD6/MXDI, MACM12, PACM12/MACM12, 6T/66, and 6I/6T, and B) 20 to 70% by weight of a glass fibre with 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; wherein the polyamide matrix C) optionally contains up to 30% by weight of the polyamide matrix a particle- and/or layer-shaped filler C selected from the group consisting of whiskers, talcum, mica, silicates, quartz, titanium dioxide, wollastonite, kaolin, silicic acids, magnesium carbonate, magnesium hydroxide, chalk, ground or precipitated calcium carbonate, lime, feldspar, barium sulphate, permanent-magnetic or magnetizable metals or alloys, glass balls, hollow glass balls, hollow-ball silicate fillers, natural layer silicates, synthetic layer silicates and mixtures thereof; and D) optionally up to 5% by weight of the polyamide matrix an additive D selected from the group consisting of heat protection agents, antioxidants, light protection agents, lubricants, mould-release agents, nucleation agents, pigments, colourants and anti-drip agents and mixtures thereof, with the proviso that the sum of A+B+C+D is 100% by weight, wherein the filled PA moulding compound is free of carbon fibres.
