Abstract: Flame-retardant polycarbonate compositions and methods for increasing the flame-retardancy of polycarbonate compositions are disclosed. A glass fiber, alumina particles, and wollastonite particles are added to polycarbonate compositions. The addition of the glass fiber, alumina particles, and wollastonite particles to the polycarbonate composition produces a polycarbonate composition having a frame-retardance rating of UL 94 5V-A at 2.3 mm thickness or less. The inventive compositions retain good surface quality.

Abstract: The present invention relates to flame-retardant polycarbonate compositions and methods for increasing the flame-retardancy of polycarbonate compositions. An α,ω-alkoxy phenyl phenyloligosiloxane compound and an alkali metal sulfonate salt are added to the polycarbonate compositions. The addition of the α,ω-alkoxy phenyl phenyloligosiloxane compound and the alkali metal sulfonate salt produces a polycarbonate composition having a flame-retardance rating of UL 94V-0 at 2 mm thickness or less.
