PROBLEM TO BE SOLVED: To provide a polypropylene resin composition capable of manufacturing polypropylene profile extrusion molding having uniform wall thickness and beautiful appearance.SOLUTION: A polypropylene resin composition for profile extrusion molding contains a propylene resin having specific MFR, soluble components at 40°C or less, mm, molecular weight distribution, branch index and melting tensile force, and a branched structure (X) of 1 to 30 wt.% and a propylene polymer polymerized by a Ziegler Natta catalyst and having MFR of 0.3 to 20 g/10 min. (Y) of 99 to 70 wt.%, has melting tensile force of 0.9 g or more, and shear rate and swell ratio satisfy specific relations. |
