<p>PROBLEM TO BE SOLVED: To provide a polyamide moulding compound which has excellent flame-retardant properties and very good long-term heat-ageing resistance without causing contact corrosion or conductive bridges.SOLUTION: The moulding compounds comprise a partially aromatic polyamide, caprolactam, a heat stabiliser, possibly a flame retardant and optionally further additives and admixtures. The polyamide moulding compound is free of metal salts and/or metal oxides of a transition metal of group VB, VIB, VIIB or VIIIB of the periodic table.</p> |
