Abstract

See full text

Described herein is a flame retardant-stabilizer mixture including as a component A, 5% to 95% by weight of aluminium diethylphosphinate (DEPAL) and/or zinc diethylphosphinate (DEPZN); as a component B, 5% to 95% 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; as a component C, 0% to 10% by weight of aluminium phosphite or zinc phosphite of the formula (II), [HP(═O)O2]2−Zn2+, and formula (III), [HP(═O)O2]2−3Al3+2; as a 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 a component E, 0% to 70% by weight of a filler and reinforcer; as a component F, 0% to 3% by weight of an organic phosphonite and/or an organic phosphite and/or mixtures with phenolic antioxidants; and as a 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. The sum total of components A-G is 100% by weight.
