Thermoplastic moulding compositions having an improved colour stability-3

Abstract

A thermoplastic moulding composition having a viscosity number of 90 to 120 ml/g comprising at least one thermoplastic polyamide, as component A), at least one of sodium hypophosphite or a hydrate of sodium hypophosphite, as component B), a colourant comprising at least one not covalently bonded sulfur atom, or two or more colourants comprising at least one sulfur containing colourant comprising at least one not covalently bonded sulfur atom, as component C) and optionally further components; a process for producing the inventive thermoplastic moulding composition comprising the step of mixing the components A), B), C) and optionally further components; the use of the inventive thermoplastic moulding composition for producing moulded articles, fibres, films and extruded articles, preferably moulded articles, which are more preferably coloured and which are most preferably coloured orange; a moulded or extruded article made of the inventive thermoplastic moulding composition; the inventive moulded or extruded article being a high-voltage component; a process for producing the inventive moulded or extruded articles by injection moulding or extrusion of the inventive thermoplastic moulding composition; and the use of a thermoplastic moulding composition having a viscosity number of 90 to 120 ml/g comprising i) at least one thermoplastic polyamide, ii) at least one of sodium hypophosphite or a hydrate of sodium hypophosphite and iii) a colourant comprising at least one not covalently bonded sulfur atom or two or more colourants comprising at least one sulfur containing colourant comprising at least one not covalently bonded sulfur atom, for improving the hydrogen sulfide smell of said thermoplastic moulding compositions.
