The invention relates to additive mixtures for plastics-containing phosphinic acid salt of the formula (I) as component Aworin Rund REthyl, M is Al, Fe, TiO or Zn, m is 2 to 3, preferably 2 or 3, andp = (4 - m) / 2-compound selected from the group of the Al, Fe, TiO or Zn salts of ethylbutylphosphinic acid, dibutylphosphinic acid, ethylhexylphosphinic acid, butylhexylphosphinic acid and / or dihexylphosphinic acid as component B-phosphonic acid salt of formula (II) as component Cvorin REthyl means Met is Al, Fe, TiO or Zn, n is 2 to 3, preferably 2 or 3, and q = (4 - n) / 2, and - copper as component D. Polymer compositions containing these additive mixtures are characterized by a excellent flame retardancy and by a very good laser markability or laser weldability. |
