▎ 摘  要

NOVELTY - A polypropylene-based resin composition comprises (A) 30-70 wt.% highly crystalline polypropylene-based resin having an isotactic peptide fraction of 96% or more by C13-NMR method, (B) 1-30 wt.% high fluidity polypropylene-based resin, (C) 10-70 wt.% carbon-based filler having an average particle size of 50-200 mu m (excluding 200), (D) 0-20 wt.% inorganic fibrous fillers having an average diameter of 10-15 mu m and an average length of 3-6 mm, and (E) 0-5 wt.% compatibilizer. USE - Polypropylene-based resin composition used for forming molded article e.g. automobile interior and exterior components and electrical and home appliance components (all claimed). ADVANTAGE - The polypropylene-based resin composition has excellent thermal conductivity, mechanical properties and fluidity, and produces lightweight molded article having excellent thermal conductivity, reproducibility and mechanical properties and can be reused after melting. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for polypropylene-based resin molded article, which is produced by molding the polypropylene-based resin composition.
