FIBER-REINFORCED POLYPROPYLENE RESIN COMPOSITION

摘要

A fiber-reinforced polypropylene resin composition is provided to realize improved rigidity, impact resistance, heat resistance and elongation at break, thereby improving impact absorbing property of final products. A fiber-reinforced polypropylene resin composition comprises, based on 100 parts by weight of the combined weight of (A+B+C+D): (A) 50-95 parts by weight of a polypropylene resin; (B) 5-40 parts by weight of inorganic fibers; (C) 0-15 parts by weight of a thermoplastic rubber elastomer; (D) 0-15 parts by weight of inorganic fillers; and (E) 0.3-3.0 parts by weight of a compatibilizer. The polypropylene resin is a propylene homopolymer having an isotactic index of 87-92 wt% on the NMR basis and a melt index of 0.5-35 g/10 min(230 deg.C).
