Abstract
A coated or jacketed wire or cable, and components thereof are disclosed. The coating, jacket, and components, which comprise a polyolefin and a phenolic polymeric antioxidant, exhibit outstanding oxidative thermal stability (as indicated by the increase in the oxidative inductive time (OIT)), when compared to polyolefins containing traditional non-polymeric antioxidants. A greater improvement in the thermal oxidative stability is observed after the polyolefin mixtures have been aged in water-blocking filler(s).
