Abstract:
A thermoplastic resin composition comprising (A) from 35 to 85% by weight of a polypropylene resin, (B) from 10 to 35% by weight of an elastomer, (C) from 2 to 30% by weight of an inorganic filler and (D) from 5 to 15% by weight of a resin, wherein the resin (D) has a melt tension (MT), measured at a winding speed of 15.7 m/min, of not less than 0.03 N and less than 0.1 N and a swelling ratio (SR), measured at 220Â° C., an L/D of an orifice of 40 and a shear rate of 1.2Ã—103 secâˆ’1, of 1.8 or more, and the time required for the resin (D) until the ratio (G(t)/G(0.02)) of the relaxation elastic modulus G(t) measured at 210Â° C. to the relaxation elastic modulus G(0.02) in a time of 0.02 second reaches 0.01 is not less than 5 seconds and less than 10 seconds, provided that the percentages are based on the total amount of the components (A), (B), (C) and (D).
