Abstract
Polymeric compositions comprising a polybutylene terephthalate; a low-density polyolefin selected from a low-density polyethylene, a polyolefin elastomer, or combinations thereof; and a maleated ethylene-based polymer. Optical cable components fabricated from the polymeric composition. Optionally, the polymeric composition can further comprise one or more additives, such as a filler. The optical fiber cable components can be selected from buffer tubes, core tubes, and slotted core tubes, among others.
