Document Type and Number:
Japanese Patent JP7308011
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a propylene-based resin composition having excellent balance among rigidity, impact resistance and hardness.SOLUTION: A propylene-based resin composition contains 55 pts.mass or more and less than 75 pts.mass of a propylene-based polymer (α) having a melt flow rate (MFR) at 230°C and a load of 2.16 kg obtained according to ASTM D1238E of 0.1-500 g/10 min, more than 25 pts.mass and 45 pts.mass or less of an olefinic resin (β) satisfying specific requirements other than the propylene-based polymer (α), where the total of the propylene-based polymer (α) and the olefinic resin (β) is 100 pts.mass, and 1-50 pts.mass of an inorganic filler (F), where bending elastic modulus measured according to JIS K 7171 is in a range of 600-4,000 MPa.SELECTED DRAWING: None
