A thermoplastic resin composition comprises: by weight,n (a) 50to 90% of an olefin polymer composition comprising 10to 90% by weight of an ethylene polymer having a melt flow rate of 3 g/10 min or less, a specific gravity of 0.930 or more and Q value of 3 to 15 and 90 to 10% by weight of a crystalline propylene polymer having a melt flow rate of 6 g/10 min and Q value of 5 to 15, (b) 5 to 40% of a styrene polymer, (c) 2 to 30% of a thermoplastic styrene block copolymer rubber, and (d) 10 to 70% of an inorganic filler. n The resin composition has a good balance between stiffness and impact resistance, and excellent deep drawing characteristics and a sheet thereof is stiff. |
