PROBLEM TO BE SOLVED: To provide a polypropylene resin composition for a heterogeneous extrusion molding having improved moldability, high melt tenacity and small shear rate dependence of melt elasticity, and to provide a heterogeneous extrusion molded material therefrom. SOLUTION: This polypropylene resin composition having improved moldability is composed of (A) 20-94.99 wt.% of polypropylene having 0.1-10 g/10 min MFR under 2.16 kg load at 230 deg.C, (B) 0.01-20 wt.% of polytetrafluoroethylene, (C) 5-60 wt.% of an inorganic filler and (D) 0-40 wt.% of polyethylene having 0.01-10 g/10 min MFR under 2.16 kg load at 190 deg.C and the heterogeneous molded material is composed of the resin composition.
