THERMOPLASTIC POLYMER COMPOSITION, MOLDED ARTICLE FORMED FROM SAME, AND ELECTRIC WIRE

摘要

Disclosed is a thermoplastic polymer composition with a superior balance of mechanical strength, elongation at break, hardness, flexibility, and heat resistance. Also disclosed are a molded body formed from this composition and an electric wire having an insulator and/or a sheath that uses this composition. Specifically disclosed is a thermoplastic polymer composition containing 1 -350 parts by mass of a filler (D) to 100 parts by mass of a polymer component formed from 50 - 90% by mass of an ethylene/unsaturated ester compound copolymer (A), 1 - 40% by mass of a propylene polymer (B) having a melting point of 120 - 170°C measured by a differential scanning calorimeter (DSC), and 1 - 49% by mass of a propylene polymer (C) having a melting point of less than 120°C measured by a differential scanning calorimeter (DSC) or a melting point that is not measured (the total of (A), (B) and (C) being 100% by mass).
