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, TiO.sub.p 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.

A first composition is disclosed that includes a fire-resistant thermoplastic resin. The fire-resistant thermoplastic resin includes 1-20 wt % of an aryl phosphate, includes 1-20 wt % of a phosphate polymer, and 60%-98% of a (meth)acrylic polymer, including units from at least one monomer, wherein the monomer is chosen from methyl methacrylate, acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters, acrylonitrile and maleic anhydride. The first composition may further include a fabric or a composite material that is embedded with the fire-resistant thermoplastic resin. In some instances, the aryl-phosphate and the phosphonate polymer synergistically reduce an effective heat of combustion, a peak heat release, or a flame time as compared to a second composition that contains only one of the aryl phosphate or the phosphonate polymer.
