The invention relates to a composition for production of a thermoplastic moulding compound, wherein the composition comprises or consists of the following constituents: (A) 50-90% by weight of aromatic polycarbonate or polyestercarbonate having a relative solution viscosity of at least 1.285, measured in CH2Cl2 as solvent at 25 DEG C and a concentration of 0.5 g/100 ml, (B) 1-10% by weight of rubber-modified graft polymer, (C) 2.5-10% by weight of boron nitride, (D) 4-20% by weight of talc, (E) 2-20% by weight of phosphorus-containing flame retardant, (F) 0-20% by weight of further additives, and to a process for producing the thermoplastic moulding compound, to the moulding compound itself, to the use of the moulding compound for production of mouldings and to the mouldings themselves.
