Flame-resistant polyamide compositions having a filament ignition temperature of at least 775 ° C and containing polyamide having a melting point of 290 ° C or lower as component A, fillers and / or reinforcing substances as component B; a phosphinic acid 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 from 2 to 3 and p = (4 - m ) / 2; a compound selected from the group of Al, Fe, TiO p or Zn salts of ethylbutylphosphinic acid, dibutylphosphinic acid, ethylhexylphosphinic acid, butylhexylphosphinic acid and / or dihexylphosphinic acid as component D; a phosphonic acid salt of formula (II) as constituent 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 a melamine polyphosphate having an average degree of condensation of 2 to 200 as constituent F. These polyamide compositions can be used for the production of fibers, films and moldings, especially for applications in the electrical field and electronic. |
