<P>PROBLEM TO BE SOLVED: To provide a polyethylene for foaming blow molding, which exhibits high foamability, moldability, mechanical strength, good surface appearance and excellent durability, and raises thermal insulation, sound absorbency and rigidity, and is suitable for a lightweight container. Ž<P>SOLUTION: The polyethylene for foaming blow molding is used for production of a foamed blown molding, and satisfies the physical properties (a) to (d) below. The physical property (a) is that the density is 0.935 to 0.970 g/cm<SP>3</SP>. The physical property (b) is that the melt flow rate (MFR) is 0.05 to 0.80 g/10 min at a temperature of 190°C and a load of 2.16 kg. The physical property (c) is that the ratio of the weight-average molecular weight (Mw) and the number-average molecular weight (Mn) as measured by gel permeation chromatography (GPC) is 4.0 to 30. The physical property (d) is that the melt tension (MT) is 6.0 to 25 cN. Ž<P>COPYRIGHT: (C)2011,JPO&INPIT Ž |
