Abstract (en)

[origin: WO2019030252A1] The invention relates to flame-retardant polyamide compositions with a high glow wire ignition temperature of at least 775 °C, containing a polyamide having a melting point of less than or equal to 290 °C as component A, fillers and/or reinforcing materials as component B, phosphinic acid salt of formula (I) as component C, wherein R1 and R2 represent ethyl, M represents Al, Fe, TiOp or Zn, m represents 2 to 3, and p = (4 – m) / 2, a compound selected from the group of Al, Fe, TiOp or Zn salts of ethyl butylphosphinic acid, dibutylphosphinic acid, ethylhexylphosphinic acid, butylhexylphosphinic acid and/or of dihexylphosphinic acid as component D, phosphonic acid salt of formula (II) as component E, wherein R3represents ethyl, Met represents Al, Fe, TiOq or Zn, n represents 2 to 3, and q = (4 – n) / 2, and a melamine polyphosphate having an average degree of condensation of 2 to 200 as component F. The polyamide compositions can be used to produce fibers, films, and moulded bodies, in particular for applications in the electrical and electronics fields.
