Abstract
High temperature nylon compounds that are flame retardant using non-halogenated ingredients are disclosed. Poly phenylene ether, or alternatively the combination of polyphenylene ether and bismaleimides, act as synergists with polyphosphonate to achieve a V-0 rating in a UL 94 test at thicknesses of about 3.18 mm or, preferably, about 1.59 mm.

A flame retardant high temperature nylon compound, comprising:
- (a) high temperature nylon;
- (b) polyphosphonate;
- (c) polyphenylene ether;
- (d) stabilizer;
- and
- (e) optionally polytetrafluoroethylene;
- wherein the compound comprises at least about 10 weight percent polyphosphonate and at least about 5 weight percent polyphenylene ether,
- wherein a combined amount of polyphosphonate and polyphenylene ether is at least about 30 weight percent, and
- wherein the compound is injection molded and tested at a thickness of 3.18 mm or less, the compound has a UL 94 rating of V-0.
