From viewpoints of environmental protection and reduction in manufacturing costs, it is desirable to use non-cross-linked polyethylene as an insulating material for power cables. A new type of polymerized polyethylene using a single-site catalyst has an advantage of its high melting point, but its processability is very poor because of its high viscosity. Therefore, blends of this polyethylene and conventional low-density polyethylene with different blending ratios are examined in this research. We found that the blend with a blending ratio of 1:1 has an appropriate melt tension and adequate viscosity at a shear rate suitable for cable manufacturing. Furthermore, the blend has a superior thermal property and a high dielectric strength for both DC and impulse voltages.
