In the present invention, as the − component A, the phosphinate of the formula (I), where R1 and R2 are ethyl, M is Al, Fe, TiO or Zn, m is 2-3, preferably 2 or 3 and p = (4-m) / 2, -as component B, ethylbutylphosphinic acid, dibutylphosphinic acid, ethylhexylphosphinic acid, butylhexylphosphinic acid, and / or dihexylphosphinic acid Al, Fe, Compounds Selected from the Group of TiOs or Zn Salts-Phosphites of Formula II as component C where R3 is ethyl, Met is Al, Fe, TiOq or Zn, n is 2-3, preferably. 2 or 3, q is (4 to n) / 2, and-for a mixture of additives for plastics containing component D as antimony, tin and / or indium. A polymer composition containing a mixture of these additives is characterized by excellent flame retardancy and very good laser markability or laser weldability. |
