The described is a flame-retardant polyamide composition with a heat distortion temperature HDT-A of at least 280 ° C, which includes-polyamide with a melting point of not less than 290 ° C as component A;-filler and / or Or enhancer, as component B;-Phosphonic salt of formula (I), as component C , Where R 1 and R 2 are ethyl, M is Al, Fe, TiO p or Zn, M is 2 to 3, and p = (4-m) / 2-compound selected from ethyl butyl phosphonic acid (ethylbutylphosphinic acid), dibutylphosphinic acid, ethylhexylphosphinic acid, ethylhexylphosphinic acid, butylhexylphosphinic acid and / or Al, Fe, dihexylphosphinic acid Group consisting of TiO p and Zn salts as component D; and-monoethylphosphinic salt of formula II as component E , Where R 3 is ethyl, Met is Al, Fe, TiO q or Zn, n is 2 to 3, and q = (4-n) / 2. The polyamide composition can be used to manufacture fibers, films, and plastic objects, especially in the fields of electronics and electrical appliances. |
