    摘要: TRXLPE-type cable sheaths are prepared by a method in which a solid polymer is mixed with a liquid water tree-resistant agent either by dosing or direct injection. In the dosing method, the solid polymer, e.g., high pressure LDPE, is sprayed or otherwise contacted with the liquid agent, e.g., PEG, the agent is allowed to absorb into the polymer, and the polymer with absorbed agent is then fed to an extrusion apparatus for extrusion over a sheathed or unsheathed wire or optic fiber. In the direct injection method, the solid polymer is first fed to an extrusion apparatus, and the liquid agent is sprayed or otherwise contacted with the polymer before the two are blended with one another through the action of the mixing elements of the apparatus.

    摘要: Shear thickening compositions can function in an energy or communications transmission cable to provide enhanced protection against externally applied forces, e.g., cutting or puncture from a shovel. As a free or bound layer, or when used via impregnation into a substrate used for an internal component or wrap, the shear thickening composition provides protection against mechanical damage that far surpasses conventional technologies. In foamable compositions for cable components, the shear thickening composition provides enhanced integrity of the polymer melt for enhanced foam performance. As a flame retardant component, the shear thickening composition provides an enhanced char formation mechanism for superior flame retardance.
