Abstract:
PROBLEM TO BE SOLVED: To provide a multiphase semiconductive shield composition with reduced conductive filler loading while maintaining a high level of conductivity and improving processability.SOLUTION: The present invention is a polymer composite made from or containing: (i) a phase I material consisting essentially of a polar copolymer of ethylene and an unsaturated ester having 4 to 20 carbon atoms; (ii) a phase II material consisting essentially of a nonpolar, low density polyethylene; and (iii) a conducting filler material dispersed in the phase I material and/or the phase II material in an amount sufficient to be equal to or greater than the amount required to generate a continuous conducting network in the phase I and phase II materials. The invention also includes articles made from the polymer composite.
Abstract:
A peroxide-crosslinkable composition comprising: (A) A peroxide-crosslinkable polymer, e.g., a polyethylene; (B) A nitrogenous base, e.g., a low molecular weight, or low melting, or liquid nitrogenous base such as triallyl cyanurate (TAC); and (C) One or more antioxidants (AO), e.g., distearylthiodipropionate (DSTDP). The composition is useful in the manufacture of insulation sheaths for high and extra high voltage wire and cable.
Abstract:
La presente invención se refiere a una composición reticulable con peróxido que comprende: (A) un polímero reticulable con peróxido, por ejemplo, un polietileno, (B) una base nitrogenada, por ejemplo, una base nitrogenada de bajo peso molecular, o bajo punto de fusión, o líquida tal como cianurato de trialilo (TAC); y (C) uno o más antioxidantes (AO), por ejemplo, diesteariltiodipropionato (DSTDP). La composición es útil en la manufactura de fundas aislantes para alambre y cable de alta y extra alta tensión.
