Abstract:
A flame-retardant polyamide composition can be prepared with a glow wire ignition temperature of not less than 775° C. Such a composition can include a polyamide having a melting point of not more than 290° C. as component A, fillers and/or reinforcers as component B, a phosphinic salt of the formula (I) as component C, a compound selected from the group of the Al, Fe, TiOp and Zn salts of ethylbutylphosphinic acid, of dibutylphosphinic acid, of ethylhexylphosphinic acid, of butylhexylphosphinic acid and/or of dihexylphosphinic acid as component D, a phosphonic salt of the formula (II) as component E, and a melamine polyphosphate having an average degree of condensation of 2 to 200 as component F. Additional components can be included in the composition.
