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).

Methods for processing HDPE and/or MDPE recyclates including, but not limited to, polyethylene and polypropylene and compositions therefrom are provided. HDPE and/or MDPE recyclate feedstocks can be visbroken to improve processing characteristics and/or devolatilized to remove waste byproducts to produce processed HDPE recyclate and/or processed MDPE recyclates. Processed HDPE recyclate and/or processed MDPE recyclates are compounded with pre-consumer polyolefins to produce blend compositions having acceptable or even improved processing characteristics. Such pre-consumer polyolefins can also be visbroken to further tailor processing characteristics of such polymer blends. A combination of extruders and/or extruder zones can be used at the same or different locations for visbreaking and/or compounding of both HDPE and/or MDPE recyclate and/or pre-consumer polyolefins.
