Abstract: A composition including a compatibilized blend of polyamide, polyphenylene ether and a flameproofing agent that synergistically interact such that plaques produced from the composition pass a glow wire ignition temperature test (GWIT) without producing a flame. Advantageously, the flameproofing agent is non-halogenated and the compositions also free of other halogen containing components. In addition, the compositions are free of fillers and are unexpectedly still able to pass the noted tests.
