Flame-Retardant, Moisture-Cured Wire and Cable Constructions with Improved Glancing Impact Performance

摘要

Articles made from a moisture-curable, polymeric composition comprising in weight percent based on the weight of the composition:(A) 2 to less than 80 weight percent (wt %) of an ethylenic polymer with (1) a crystallinity at room temperature of 34% to 55%, or 65% to 80%, and (2) a melt index (I₂) of 0.1 to 50 decigrams per minute (dg/min);(B) 3 to 30 wt % of a halogenated flame retardant;(C) 3 to 30 wt % an inorganic antimony flame retardant; and(D) 0 to 10 wt % of at least one of an inorganic flame retardant other than the inorganic antimony flame retardant, e.g., zinc oxideexhibit enhanced ACBD properties in comparison to articles alike in all respects except made from a composition comprising an ethylenic polymer without the requisite crystallinity at room temperature.
