A cross linkable composition comprises a copolymer part consisting of a copolymer of ethylene and an organic acid salt of an alkyl, alkenyl, or alkynyl radical comprising 26% to 42% by weight of monomer, representing 50% to 90% by weight of the polymer phase; and an acrylonitrile-butadiene copolymer having 25% to 50% by weight acrylonitrile, representing 10% to 50% by weight of the polymer phase. It further has carbon black having a specific surface area of less than 170 m2/g, representing 40% to 75% by weight of the polymer phase and additives such as antioxidants, anti-coppers, peroxides, silanes, in quantities that generally remain below 5% of the polymer phase.
