  • Cable and composition
    Patent number: 10679768
    Abstract: A cable having one or more conductors surrounded by at least an inner semiconductive layer, an insulation layer and an outer semiconductive layer, in that order, wherein the insulation layer is not crosslinked and has at least 90 wt % of a polymer composition, said polymer composition having: (I) 85.0 to 99.5 wt % of an LDPE; and (II) 0.5 to 15.0 wt % of an HDPE having a density of at least 940 kg/m3 or 1.5 to 15.0 wt % of an ultra-high molecular weight polyethylene having a Mw of at least 1,000,000.
