description | PURPOSE: A polycarbonate-based resin composition and molded products using the same are provided to improve real flow characteristic, fire retardance, shock resistance, heterogeneity, and heat resistance. CONSTITUTION: A polycarbonate-based resin composition comprises a polycarbonate resin, a polycarbonate - polysiloxane copolymer and siloxane copolyester. 0.1-6 weight% of the siloxane copolyester is included based on total composition. The siloxane copolyester has a number average molecular weight of 5500-7500 g/mol. The number average molecular weight of the polyester among the siloxane copolyester is 1,000-3,000 g/mol. The siloxane copolyester is a block copolymer including polyester block and the polysiloxane block having an ABA form. |
