    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.

    摘要: The present invention is a crosslinked automotive wire comprising a metal conductor, a flame retardant insulation layer surrounding the metal conductor, and optionally, a wire jacket surrounding the insulation layer. The automotive wire passes the specifications of one or more several automotive cable testing protocols: (a) SAE J-1128, (b) ISO-6722, (c) LV 112, (d) Chrysler MS-8288, and (e) Renault 36-36-05-009/-L. In particular, the flame retardant insulation layer is prepared from a crosslinkable thermoplastic polymer and a metal carbonate. The flame retardant composition for making the insulation layer demonstrates economic and processing improvements over conventional solutions. The present invention is also a method for preparing a low tension primary automotive wire and the automotive wire made therefrom.
