Abstract
A cable comprising one or more electrical conductors or communications media, or a core of two or electrical conductors or communications media, each electrical conductor, communications medium, or core being surrounded by a composition comprising: PA1 (A) about 40 to about 93 percent by weight of at least one resin selected from the group consisting of ethylene/vinyl acetate copolymer, ethylene/ethyl acrylate copolymer, and an ethylene/alpha-olefin copolymer having a density equal to or less than 0.915 gram per cubic centimeter. PA1 (B) about 5 to about 50 percent by weight of a linear ethylene/alpha-olefin copolymer produced by using a single-site metallocene catalyst and having a melt flow rate of about 0.5 to about 50 grams per 10 minutes; a density of 0.86 to 0.91 gram per cubic centimeter; and an Mw/Mn ratio equal to or less than about 3.0; PA1 (C) about 2 to about 40 percent by weight of an ethylenic resin modified PA2 with a compound or compounds containing a functional group, and PA2 for each 100 parts by weight of components (A), (B), and (C), combined, PA1 (D) about 50 to about 250 parts by weight of an inorganic flame retardant; and PA1 (E) about 0.05 to about 10 parts …
