    摘要: The present invention is a plenum cable component with excellent fire retardant and aging properties. The plenum cable component is prepared from a polyolefin-based composition, containing an olefinic polymer and a surface treated metal hydroxide. Depending upon the surface treatment, the composition may comprise other components. The present invention is also a method for selecting a composition for preparing the plenum cable component as a separator and a method for preparing a communications cable therefrom.

    摘要: Magnesium oxide (MgO) compounded into a polymer can subsequently be hydrated in-situ within the polymer to form magnesium hydroxide. In the case of silane-based or peroxide-based crosslinkable resins, the MgO hydration and polymer crosslinking can be done in a single process step, or in sequential steps. In the case of non-crosslinkable compounds, hydration can be carried out after compounding (no crosslinking step). In all cases, steam CV, sauna, or hot water bath are options for hydration. This approach enables preparation of polymer compounds that are flame retarded with metal hydrates yet free of the traditional limitations posed by shelf instability, extrusion scorch, undesired dehydration, and processing temperature limitations posed by metal hydrates.
