A cable and a cable jacket comprising a polyethylene composition

The present invention discloses a cable comprising a layer of a polyethylene composition characterized in that the polyethylene composition comprises: (A) from 5% to 95% by weight of the total composition of at least one first polymer which is an ethylene/alpha-olefin interpolymer having: (i) a density from 0.865 g/cm3 to 0.95 g/cm3, (ii) a molecular weight distribution (Mw/Mn) from 1.8 to 3.5, (iii) a melt index (I2) from 0.001 g/10 min to 10 g/10 min, and (iv) a CBDI greater than 50%, (B) from 5% to 95% by weight of the total composition of at least one second polymer which is a heterogeneously branched ethylene polymer or homogeneously branched ethylene homopolymer having a density from 0.9 g/cm3 to 0.965 g/cm3. The cable of the present invention has superior mechanical properties and processability relative to conventional cable using current polymers such as low density polyethylene (LDPE), linear low density polyethylene (LLDPE), and polyvinylchloride (PVC).
