Drip-retardant plasticized polyphenylene ether compositions containing microfibrillar poly(tetrafluoroethylene)

摘要

There are provided drip-retardant, plasticized thermoplastic compositions which comprise, in admixture, a polyphenylene ether resin, a plasticizer in an amount at least sufficient to provide a plasticized composition after molding, and a microfibrillar poly(tetrafluoroethylene)resin in an amount at least sufficient to render the thermoplastic composition non-dripping when molten. The present compositions meet even more stringent standards than the UL-94 flame test.
