Polymer composition having a density between 0.940 and 0.950 inclusively and a fluidity index less than 2 dg/min comprises 50 to 60% of at least one copolymer A of ethylene and at least one alpha -olefin having 3 to 12 carbon atoms, the said copolymer having a density between 0.932 and 0.940 and 40 to 50% of at least one ethylene polymer B having a density between 0.952 and 0.960, the fluidity index of A being between 1.5 and 5 dg/min, and the fluidity index of B being between 0.15 and 0.4 dg/min. The compositions may be used for insulating conductors such as telephone wires. |
