FLEXIBLE CROSSLINKED CABLE INSULATION AND METHODS FOR MAKING FLEXIBLE CROSSLINKED CABLE INSULATION

摘要

Crosslinkable polymeric compositions comprising (a) 10 to 89 weight percent of an ethylene-based interpolymer having the following properties: (i) a density of 0.93 g/cm3 or less, (ii) a high-shear viscosity (V100) at 190 C and 10 % strain of 1,200 Pa⋅s or less, (iii) a shear thinning ratio (V0.1/V100) at 190 C and 10 % strain of at least 8, and (iv) a melt index (I2) greater than 1 g/10 minutes; and (b) 10 to less than 90 weight percent of a filler, where the ethylene-based interpolymer is not prepared in a high-pressure reactor. Such crosslinkable polymeric compositions may be employed as insulation layers in flexible power cables.
