THERMALLY CONDUCTIVE THERMOPLASTIC RESIN COMPOSITION HAVING GOOD ELECTRO-CONDUCTIVITY AND MOLDED ARTICLES THEREOF

摘要

PURPOSE: A conductive thermoplastic resin composition is provided to have excellent electric conductivity, mechanical properties, and process efficiency, and to be able to provide products which not generate dust. CONSTITUTION: A conductive thermoplastic resin composition comprises: 100.0 parts by weight of polycarbonate resin; 15-25 parts by weight of rubber-modified vinyl-based graft copolymer resin; 10-15 parts by weight of styrene-acrylonitrile resin; and 0.5-2.0 weight% of carbon nanotubes based on 100 weight% of the sum of the resins. The weight average molecular weight(Mw) of the polycarbonate resin is 20,000-35,000. The rubber modified vinyl graft copolymer is an acrylonitrile-butadiene-styrene graft copolymer.
