Abstract
A long glass fiber filler reinforced resin material for molding includes a masterbatch formed of a composite of a matrix resin with a polypropylene (PP) component and a long glass fiber filler and a diluent resin made from an ethylene-propylene block copolymer. The above-described matrix resin of the masterbatch includes the PP component having a pentad isotactic index of at least 95%, and a melt flow rate (MFR) of the matrix resin of the masterbatch is 100 to 500 g/10 min and larger than six times a melt flow rate of the diluent resin. The long glass fiber filler is in a content of 30 to 50 mass percent with respect to a total mass thereof.
