Abstract

Articles made from a moisture-crosslinkable, polymeric composition comprising in weight percent based on the weight of the composition: (A) 10 to 99.99 wt % of a nonpolar ethylenic polymer grafted with silane functionality (Si-g-npPE), the npPE having the following properties before grafting: (1) a vinyl content of 0.2 to 0.7 per 1,000 carbon atoms, (2) a melt index of 1.5 to 7.0 dg/min, (3) a density of 0.913 to 0.965 g/cc, and (4) a molecular weight distribution (Mw/Mn) of equal to or less than 8; (B) 0.01 to 20 wt % of a silanol condensation catalyst; and (C) 0 to 70 wt % of a flame retardant additive; exhibit one or more of desirable (a) silane grafting efficiency; (b) hot creep performance as a cable jacket/insulation after moisture crosslinking; (c) retained dielectric strength after glancing impact as a moisture crosslinked cable construction; and (d) crush resistance as a moisture crosslinked cable construction.
