摘要:
A cable including at least one core having at least one transmissive element and at least one coating layer made from a coating material, wherein the coating material has at least a first polyethylene having a density not higher than 0.940 g/cm3, preferably not lower than 0.910 g/cm3, more preferably 0.915 g/cm3 to 0.938 g/cm3, and a Melt Flow Index (MFI), measured at 190° C. with a load of 2.16 Kg according to ASTM D1238-00 standard, of 0.05 g/10′ to 2 g/10′, preferably 0.1 g/10′ to 1 g/10′; the first polyethylene being obtained from a waste material; at least a second polyethylene having a density higher than 0.940 g/cm3, preferably not higher than 0.970 g/cm3, more preferably 0.942 g/cm3 to 0.965 g/cm3. Preferably, the coating layer is a cable external layer having a protective function.
