Abstract:
A flame retardant composition and method for making flame retardant articles. The flame retardant composition can include a silicone polyetherimide, an fibrillated polytetrafluoroethylene, and a zinc borate. The silicone polyetherimide can be present in an amount of from about 99.6 to about 80.0 percent by weight. The silicone polyetherimide can have from about 5 to about 50 percent by weight dimethyl siloxane units, and less than about 100 ppm amine end groups. The fibrillated polytetrafluoroethylene can be present in an amount of from more than about 1.25 to about 5.0 percent by weight. The fibrillated polytetrafluoroethylene can be encapsulated in a polystyrene, a poly(styrene acrylonitrile), a poly(methyl methacrylate), a polycarbonate, a polyetherimide, a polysulfone, and combinations thereof. The zinc borate can be present in an amount of more than 0 to about 10 percent by weight.
