Flame retardant thermoplastic polycarbonate compositions, use and method thereof
A thermoplastic composition contains about 20 to about 90 wt. % of a polycarbonate resin; up to about 35 wt. % of an impact modifier; about 0.5 to about 30 wt. % of a polysiloxane-polycarbonate copolymer; and about 0.5 to about 20 wt. % of a phosphorus-containing flame retardant, each based on the t...

Summary: | A thermoplastic composition contains about 20 to about 90 wt. % of a polycarbonate resin; up to about 35 wt. % of an impact modifier; about 0.5 to about 30 wt. % of a polysiloxane-polycarbonate copolymer; and about 0.5 to about 20 wt. % of a phosphorus-containing flame retardant, each based on the total combined weight of the thermoplastic composition, exclusive of any filler. An article of manufacture having a wall having a thickness of 3 mm or less may be made using the composition, e.g., by molding, extruding, or shaping the above-described composition into an article. Alternatively, an article may be made by ultrasonically welding a first part comprising the foregoing composition a second part. |
