ABSTRACT:
A propylene-based resin composition for a pipe member, and a pipe member and multi-layered pipe member formed using that the same, which is comprised of (a) 65 to 90 parts by mass of a propylene resin homopolymer, (b) 10 to 25 parts by mass of talc having an average particle size of 1 to 10 μm and (c) 1 to 10 parts by mass of at least one kind of a rubber component selected from an ethylene-propylene-based rubber, an ethylene-butene-based rubber, a styrene-butadiene-based rubber and a styrene-isoprene-based rubber as main components, wherein the MFR of a melt-kneaded mixture obtained by melt kneading these components (a) to (c) is from 0.01 to 2.00 g/10 minutes.
