Abstract
The present application relates to a composition comprising the following components: A) at least one ethylene/alpha-olefin interpolymer; B) a peroxide; C) at least one filler selected from one or more carbon black samples, MgO, or a combination thereof; and optionally, at least one filler selected from silica, ZnO, CaCO3, Al (OH)3, Mg (OH)2, or a combination thereof; D) a calculated P content from 0.010 wt % to 0.300 wt %, based on the weight of the composition, and wherein the calculated P content is the calculated content the phosphorus element present in one or more phosphate compounds selected from Structure 1 below: O═P (OR1) (OR2) (OR3) (Structure 1), wherein R1, R2 and R3 are each, independently, selected from i) a non-aromatic hydrocarbon or ii) a non-aromatic hydrocarbon comprising at least one heteroatom, excluding P.
