The invention relates to flame retardant polyamide compositions containing - polyamide having a melting point of less than or equal to 290 ° C as component A, - fillers and / or reinforcing agents as component B, - phosphinic acid salt of formula (I) as component C wherein R1 and R2 are ethyl, M Al , Fe, TiOp or Zn, m is 2 to 3, and p = (4 - m) / 2 is 15 - compound selected from the group of Al, Fe, TiOp or Zn salts of ethylbutylphosphinic acid, dibutylphosphinic acid which is ethylhexylphosphinic acid, butylhexylphosphinic acid and / or dihexylphosphinic acid as component D - phosphonic acid salt of the formula II as component E in which R3 is ethyl, Met is Al, Fe, TiOq or Zn, n is 2 to 3, and q = (4 - n) / 2 is - Melaminpolyphosphat with an average degree of condensation of 2 to 200 as component F, and - gray colorant as component G. The gray polyamide compositions can be used for the production of fibers, films and Formk bodies, in particular for applications in the electrical and electronics sector. |
