1. A polyamide moulding composition consisting of the following components:

a) 50 to 75% by weight of at least one partially crystalline polyamide consisting of at least one diamine and at least one aromatic dicarboxylic acid, wherein the at least one diamine has 4 to 18 carbon atoms and is selected from the group consisting of linear aliphatic diamines, branched aliphatic diamines, and cycloaliphatic diamines,

b) 5 to 20% by weight of at least one fibrous reinforcing agent,

c) 10 to 40% by weight of at least one non-sized filler which is different from the fibrous reinforcing agent in b), and wherein the at least one non-sized filler is

selected from the group consisting of milled glass fibres, milled carbon fibres, glass flakes, wollastonite, mica, phyllosilicates, and mixtures thereof, or

whiskers, or

is a mixture of at least one non-sized filler selected from the group consisting of milled glass fibres, milted carbon fibres, glass flakes, wollastonite, mica, phyllosilicates, and mixtures thereof; and whiskers, and

d) 0 to 6% by weight of at least one additive,

with the proviso that components b) and c) add up to 25 to 45% by weight and the entirety of components (a) to (d) adds up to 100% by weight,

wherein the moulding compositions a condensable outgassing resulting in a haze of a maximum of 10%, measured by determining the haze on a glass plate after a thermal treatment of pellets of the rob/amide moulding composition at 200° C. for a period of 8 hours.
