Abstract

The disclosure is directed to a thermoplastic molding composition. The composition includes A) from 10 to 98% by weight of a thermoplastic polyester; B) from 0.5 to 30% by weight of a dicarboxylic salt; C) from 1 to 30% by weight of a flame retardant combination made of C1) a halogen-containing flame retardant differing from B), and C2) an antimony oxide; and D) from 0 to 50% by weight of other additives. The total of the percentages by weight of components A) to D) is 100%. The dicarboxylic salt is represented by the following formula, where R1 to R4 are mutually independently halogen or hydrogen, wherein at least one moiety R1 to R4 is halogen, x is 1 to 3, m is 1 to 9, n is 2 to 3, and M is an alkaline earth metal, Ni, Ce, Fe, In, Ga, Al, Pb, Y, Zn, or Hg:
