Abstract
The present invention is directed to flame retardant, pigmented polycarbonate molding compositions which properties include both good flame resistance properties and virtual freedom from streaking. The compositions are particularly suitable for use in molding machines using hot runner tools. The composition of the invention comprise a thermoplastic aromatic polycarbonate resin, a flame retarding agent, pigments, polytetrafluoroethylene--ASTM Type 3--and an amount of finely divided hydrophobic silicon dioxide sufficient for providing streaking-free molded articles.
