US 2012/0238686 A1 · THERMOPLASTIC RESIN COMPOSITION AND RESIN MOLDED ARTICLE

Abstract

The present invention relates to a thermoplastic resin composition which comprises 100 parts by weight of a polyamide resin (component A) and 1 to 400 parts by weight of a granular inorganic filler (component B) comprising an inorganic filler having an average particle diameter of 0.01 to 100 μm and a water-soluble polyester resin binder, and having a bulk density of 0.4 to 1.5 g/mL; and a resin molded article obtained by molding the thermoplastic resin composition. The thermoplastic resin composition is improved in various properties such as extrusion moldability, rigidity, impact resistance, thermal stability and hue, and exhibits an excellent balance between these properties.
