Abstract (en)
[origin: WO2019030253A1] The invention relates to flame-retardant polyamide compositions with a heat deflection temperature HDT-A of at least 280 °C, containing - a polyamide with a melting point of greater than or equal to 290 °C as component A, - fillers and/or reinforcing materials as component B, - a 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 containing Al-, Fe-, TiOp- or Zn-salts of ethylbutyl phosphinic acid, dibutyl phosphinic acid, ethylhexyl phosphinic acid, butylhexyl phosphinic acid and/or dihexyl phosphinic acid as component D, and - a phosphinic acid salt of formula (II) as component E, where R3 represents ethyl, Met represents Al, Fe, TiOq or Zn, n represents 2 to 3, and q = (4 – n) / 2. The polyamide compositions can be used to produce fibres, films and moulded bodies, in particular for electrical and electronic applications.
