The present invention relates to a flame-retardant polyamide composition having a glow wire ignition temperature not lower than 775 ° C, which contains:-as component A, having a melting point not exceeding 290 ° C Polyamide,-as a filler and / or strengthening agent of component B,-as a phosphonate of formula (I) of 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,-as component D is selected from ethyl butyl Al, Fe, TiO p and Zn salts of diphosphonic acid, Al, Fe, TiO p and Zn salts of dibutylphosphonic acid, Al, Fe, TiO p and Zn salts of ethylhexylphosphonic acid, butylhexylphosphine Al, Fe, TiO p and Zn salts of acids and / or Al, Fe, TiO p and Zn salts of dihexylphosphonic acid,-Phosphonates 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, and-as component F has an average condensation of 2 to 200 Degrees of melamine polyphosphate. The polyamide composition can be used to manufacture fibers, films and shaped bodies, especially in the power industry and the electronics industry. |
