Abstract:
A long fiber-reinforced polypropylene resin composition comprising 40 to 85% by weight of (A) a long fiber-reinforced propylene homopolymer pellet and 15 to 60% by weight of (B) a propylene base block copolymer resin having a melt flow rate 230Â° C., 21.18 N; hereinafter abbreviated as MFR) of 50 g/10 mm or less, wherein the long fiber-reinforced propylene homopolymer pellet comprises(A1): 20 to 64.9% by weight of a modified propylene homopolymer obtained by modifying a propylene homopolymer with unsaturated carboxylic acid or an anhydride thereof or a mixture of the modified propylene homopolymer and an unmodified propylene homopolymer, wherein the MFR is 60 g/10 mm or more, (A2): 0.1 to 5% by weight of at least one member selected from the group consisting of simple substances, hydroxides and oxides of alkaline earth metals, and (A3): 35 to 75% by weight of long glass fibers having a length of 2 to 50 mm.
