Abstract:
The present disclosure provides a process. In an embodiment, the process includes blending a broad molecular weight distribution (MWD) ethylene-based polymer having an 121/12 ratio from 55 to 85 with a narrow MWD ethylene-based polymer having an 121/12 ratio from 20 to 50. The process includes forming a blend component comprising from 20 wt % to 45 wt % of the broad MWD ethylene-based polymer, from 80 wt % to 55 wt % of the narrow MWD ethylene-based polymer, and optional carbon black. The blend component has a density from 0.925 g/cc to 0.955 g/cc and an 121/12 ratio from 30 to 55. The process includes extruding the blend component over a conductor at a rate greater than 1.02 m/s, and forming a conductor jacket having a surface smoothness from 30 μ-inch to 80 μ-inch.
