PROBLEM TO BE SOLVED: To provide a resin for a fuel tank which is a material for a large capacity superior in the balance of molding property and durability, especially a resin for an injection mold plastic fuel tank having an excellent balance of injection molding property, durability and impact resistant and a molded article using it. SOLUTION: Polyethylene resin and the like for the injection mold plastic fuel tank for satisfying the following requirements 1-5. (1) Density is in the range of 0.940-0.970 g/cm<SP>3</SP>. (2) High load melt flow rate (HLMFR) (test condition: 190°C, 21.6 kg load) is equal to or more than 6 g/10 minutes. (3) Shear consistency at 230°C and shear rate 243 sec<SP>-1</SP>is equal to or lower than 10,000 poise. (4) Charpy impact strength at -40°C is equal to or higher than 5 KJ/m<SP>2</SP>. (5) Fracture time in a full notch creep test (measured at 80°C, 6 MPa) is equal to or longer than 80 hours. COPYRIGHT: (C)2008,JPO&INPIT |
