More Information
Summary:The present invention discloses a polycarbonate resin composition having high gloss and impact resistance and good surface properties including 100 parts by weight of a base resinincluding a polycarbonate resin (A) and a polycarbonate-polysiloxane copolymer (B); and 0.1 to 10 parts by weight of polyalkylaryl siloxane (C) having a refractive index of 1.42 to 1.59. The composition exhibits high gloss and blackness and has excellent impact resistance, heat resistance and light resistance, and superior mar resistance, which is resistance to fine scratches, and thus it is properly used for non-coating products.
