Polyethylene for pipes and joints and molded articles thereof |
| abstract |
[PROBLEMS] To provide a polyethylene for pipes and joints, which can be molded by both injection molding and extrusion molding methods, and has excellent dimensional stability of the injection molded product and pipe surface appearance. A polyethylene for pipes and joints satisfying the following characteristics (1) to (5). Characteristic (1): Melt flow rate (HLMFR) at a temperature of 190 ° C. and a load of 21.6 kg is 5 to 20 g / 10 minutes. Characteristic (2): Density (D) is 0.954-0.960 g / cm3. Characteristic (3): The ratio (Mw / Mn) of the weight average molecular weight (Mw) and the number average molecular weight (Mn) measured by gel permeation chromatography (GPC) is 15 to 27. Characteristic (4): Fracture time (FNCT) in a full notch creep test (measured at 80 ° C. and 5 MPa) is 150 hours or more. Characteristic (5): Charpy impact strength (CIS) measured at −20 ° C. is 8.5 kJ / m 2 or more. [Selection figure] None |
