  • FLAME-RETARDANT POLYAMIDE MOULDING COMPOSITIONS
    Publication number: 20180086899
    Abstract: The present invention relates to a flame-retardant polyamide moulding composition with good mechanical properties with the following constitution: (A) from 25 to 90% by weight of at least one polyamide, (B) from 5 to 60% by weight of glass fibres, where the arithmetic average of the length of these in the polyamide moulding composition is from 100 to 220 ?m, (C) from 5 to 25% by weight of at least one phosphinic salt and/or one diphosphinic salt, (D) from 0 to 20% by weight of at least one additive, where the entirety of components (A) to (D) gives 100% by weight. The invention also relates to processes for the production of moulding compositions of this type, to mouldings produced therefrom, and also to uses.
