1. A composition comprising the following components:
A) at least one ethylene/α-olefin/diene terpolymer;
B) a peroxide;
C) at least one filler comprising of carbon black and MgO in a weight ratio of carbon black to MgO from 4.0 to 8.0, and 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 wherein, for Structure 1, R1, R2 and R3 each, independently, do not contain a double bond.
