Title: THERMOPLASTIC RESIN COMPOSITION, MOLDED BODY, FUEL CELL SEPARATOR, BIPOLAR PLATE FOR REDOX FLOW CELL, AND METHOD FOR PRODUCING MOLDED BODY
Abstract:
A thermoplastic resin composition comprises (A) 50-90 mass% of a powder material and (B) 50-10 mass% of an α-olefin-based thermoplastic resin. The (B) α-olefin-based thermoplastic resin includes (B1) a first α-olefin-based thermoplastic resin (B1) having an isotactic pentad index [mmmm] of 70-99% and a melting point in the range of 120-168°C, and (B2) a second α-olefin-based thermoplastic resin having an isotactic pentad index [mmmm] of 30-60% and a melting point in the range of 60-100°C. The mass ratio of the second α-olefin-based thermoplastic resin (B2) relative to the first α-olefin-based thermoplastic resin (B1) (i.e., (B2)/(B1)) is 0.3-2.0.
