Abstract: A cable comprising one or more electrical conductors, each conductor or core being surrounded by a layer of composition comprising at least 95 percent by weight of a very low density polyethylene (VLDPE) having a number average molecular weight in the range of 10,000 to 20,000; a CHMS equal to or greater than 4.5 percent by weight as determined by SEC; and a HMS having a number average molecular weight equal to or greater than 500,000.

Abstract: For a flame retardant came, it has been surprisingly found that an insulated conductor, having at least two insulation layers, a composite dielectric constant less than or equal to 2.6, and a composite dissipation factor less than or equal to 0.005, can be prepared even though one of the insulation layers has a dielectric constant greater than 2.6 or a dissipation factor greater than 0.005. It has also been surprisingly found that an insulated conductor, having a composite dielectric constant less than or equal to 2.6 and a composite dissipation. factor less than or equal to 0.005, can be prepared with a non-halo~enated polyolefin as an insulation layer polymer, where the polyolefin having relatively poor dielectric/dissipative properties and the insulation layer composition being substantially free of halogenated or antimony trioxide flame retardant additives.

Abstract: The present invention is a communication cable comprising a plurality of twisted pair conductors, a separator, and a communication cable jacket enclosing the plurality of twisted pair conductors and the separator. The communication cable passes the requirements of NFPA-262. In particular, the separator is polyolefin-based and achieves the desired electrical and flame retardant properties. The present invention is also a method for selecting a composition for preparing the separator and a method for preparing a communications cable therefrom.

Abstract: A high-voltage direct current cable insulation is made from a blend which includes an ethylene copolymer, such as ethylene-alpha olefin copolymer, with low crystallinity to reduce physical space charge trapping sites, a polar polymer modifier in an effective amount to enhance local conductivity to leak space charge quickly when local stress is enhanced, and an ion scavenger to stabilize or neutralize the space charge to provide a composition which is an effective high-voltage DC cable insulation. A high-voltage direct current cable semiconductive shield is made from a blend that includes an ethylene copolymer, a carbon black having a low level of ionic species, a polar polymer modifier, and an ion scavenger.

Abstract: The present invention is a flame retardant composition comprising (a) a first ethylene polymer; (b) a second ethylene polymer having a density less than 0.95 grams/cubic centimeter and being modified with an unsaturated aliphatic diacid anhydride; (c) a flame retardant; and (d) an ultra high molecular weight polysiloxane. The invention also includes a coating prepared from the flame retardant composition as well as a wire-and-cable construction made by applying the coating over a wire or a cable. The invention also includes articles prepared from the flame retardant composition, such as extruded sheets, thermoformed sheets, infection-molded articles, coated fabrics, construction materials and automotive materials.
