PURPOSE: To obtain the subject resin composition excellent in impact strength, moldability, surface appearance, dimensional accuracy, cost performance, etc. CONSTITUTION: This high-specific gravity resin composition comprises 100 pts.wt. of a impact-resistant styrene-based resin and 10-200 pts.wt. of an inorganic filler. In this case, the disperse rubber phase volume fraction(RPVF) of the impact-resistant styrene-based resin stands at 30-50vol.% and the volume-average diameter (Lv) of the disperse rubber particles 1.0-5.0μm.
