Abstract: Disclosed are polymeric compositions with improved electrical breakdown strength. The polymeric compositions contain a poly-α-olefin and a voltage-stabilizing agent, which comprises an organic carboxylic ester comprising at least one aromatic ring and from 1 to 2 carboxylic alkyl ester substituents. Alternatively, the voltage-stabilizing agent can comprise trioctyl trimellitate. The present polymeric compositions exhibit improved electrical breakdown strength when applied as an insulating and/or shielding layer for power cables.

Abstract: 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 oxide exhibit 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.
