Beschreibung
Zusammenfassung:	A polypropylene complex resin composition for low-temperature injection molding, may include (A) a polypropylene resin; (B) an olefin-based elastomer; (C) an inorganic reinforcing agent; and (D) an additive, wherein (A) the polypropylene resin is a polypropylene mixed resin including: about 100 parts by weight of (A-1) a high-crystalline ethylene-propylene copolymer having an isotactic index of about 98 to 100% and a melt flow index value of about 20 to 50 g/10 min (2.16 kg, 230°C); and about 5 to 20 parts by weight of (A-2) an ultrahigh fluidity homopolypropylene having a melt flow index value of about 1,000 to 1,800 g/10 min (2.16 kg, 230°C).
