摘要

A propylene resin composition includes 0 to 80 wt % of a propylene polymer (A) having a DSC melting point of not less than 100° C., 5 to 85 wt % of a specific soft propylene copolymer (B), 0 to 40 wt % of one or more elastomers (C) selected from ethylene elastomers (C1) and styrene elastomers (C2), and 15 to 80 wt % of an inorganic filler (D) (the total of (A), (B), (C) and (D) is 100 wt %) The propylene resin composition contains the inorganic filler at a high proportion and shows excellent flexibility as well as high breaking elongation, low-temperature properties, whitening resistance, scratch resistance, abrasion resistance, stress absorption properties and flame retardancy.
