FLAME RETARDANT-STABILIZER COMBINATION FOR THERMOPLASTIC POLYMERS

The invention relates to flame retardant-stabilizer mixtures comprisingas component A 5% to 50% by weight of aluminium diethylphosphinate (DEPAL) or zinc diethylphosphinate (DEPZN),as component B 5% to 50% by weight of titanium phosphinates and/or titanyl phosphinates of the formula (I) (DEPTI),in which x is a number from 0 to 1.9, preferably 1-1.05, which means that the ratio of Ti to diethylphosphinates is from 1.9 to 2,as component C 0% to 10% by weight of aluminium phosphite or zinc phosphite of the formula (II) and (III) [HP(=O)O2]2-Zn2+ (II) [HP(=O)O2]2-3Al3+2 (III)as component D 0% to 30% by weight of a nitrogen-containing synergist and/or of a phosphorus-containing and/or nitrogen-containing flame retardant,as component E 0% to 70% by weight of a filler and reinforcer,as component F 0% to 3% by weight of an organic phosphonite or an organic phosphite and mixtures with phenolic antioxidants and as component G 0% to 3% by weight of an ester and/or salt of long-chain aliphatic carboxylic acids (fatty acids) typically having chain lengths of C14 to C40, where the sum total of the components is always 100% by weight.
