THERMOPLASTIC POLYCARBONATE RESIN COMPOSITION

摘要

The present invention provides a thermoplastic polycarbonate resin composition including: about 50 to about 70 wt% of a polycarbonate resin; about 5 to about 20 wt% of a vinyl cyanide compound-conjugated diene-vinyl aromatic hydrocarbon copolymer; about 10 to about 30 wt% of a polyester resin; about 3 to about 15 wt% of a maleimide-based copolymer; about 2 to about 10 wt% of an impact modifier; and about 0.1 to about 1.0 wt% of a nucleating agent, wherein the polycarbonate resin has a melt index of about 2 to about 20 g/10 min (300 °C, 2.16 kg). The thermoplastic polycarbonate resin composition has excellent chemical resistance so as not to be damaged even by external chemicals, and at the same time, has excellent mechanical properties, including stiffness, impact resistance and heat resistance, and thus can be widely used in the electrical/electronic field, the industrial material field and the field of vehicle interior components, and particularly, satisfies the optimal requirements for vehicle interior materials.
