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.

Abstract: Polymeric compositions comprising a high-density polyethylene, a crystalline polypropylene, and an olefin block composite. Optical cable components fabricated from an extrudable polymeric composition of high-density polyethylene, a crystalline polypropylene, and an olefin block composite. Optionally, the polymeric composition can further comprise a nucleating agent. The polymeric composition may also contain one or more additives. The optical fiber cable components can be selected from buffer tubes, core tubes, and slotted core tubes, among others.
