Abstract

Cette invention a trait à un câble comportant une couche obtenue à partir d'une composition à base de polyéthylène constituée, d'une part, (A), de 5 à 95 pour cent en poids de la composition totale d'au moins un premier polymère, en l'occurrence un interpolymère d'éthylène/ alpha -oléfine, (i) d'une densité comprise entre 0,865 et 0,95 g/cm<3>, (ii) d'une répartition des masses moléculaires (Mw/ Mn) comprise entre 1,8 et 3,5, (iii) d'un indice de fusion (I2) s'échelonnant entre 0,001 g/10 min. et 10 g/10 min. et, (iv) d'un indice de largeur de répartition de composition supérieur à 50 pour cent et, d'autre part, (B), de 5 à 95 pour cent en poids de la composition totale d'au moins un second polymère, en l'occurrence un polymère d'éthylène ramifié de façon hétérogène ou un homopolymère d'éthylène ramifié de façon homogène, d'une densité comprise entre 0,9 et 0,965 g/cm<3>. Le câble selon l'invention possède des propriétés mécaniques ainsi qu'une aptitude au façonnage supérieures à celles des câbles classiques faisant appel à des polymères courants, du type polyéthylène basse densité (PEBD), polyéthylène basse densité à structure linéaire (PEBDL) et poly(chlorure de vinyle) (PVC).
