Abstract
Foreliggende oppfinnelse beskriver en kabel omfattende et lag av et polyetylenpreparat som karakteriseres ved at det omfatter. (A) fra 5 prosent til 95 prosent, av det totale preparatets vekt, av minst en første polymer som er en etylen/a-olefin interpolymer som har (i) en tetthet fra 0,865 g/cm3 til 0,95 g/cm3, (ii) en molekylvektfordeling (MJMJ fra 1,8 til 3,5, (iii) en smelteindeks ((2) fra 0,001 g/10 min. til 10 g/10min. og (iv) en CBDI-verdi som er større enn 50 prosent, (B) fra 5 prosent til 95 prosent, av det totale preparatets vekt, av minst en andre polymer som er en heterogent forgrenet etylenpolymer eller homogent forgrenet etylen-homopolymer med en tetthet fra 0,9 g/cm3 til 0,965 g/cm3. Kabelen ifølge foreliggende oppfinnelse har overlegne mekaniske egenskaper og prosesserbarhet i forhold til konvensjonelle kabler som an- vender nåværende polymerer så som lavtetthetspolyetylen (LDPE), lineær lavtetthetspolyetylen (LLDPE) og polyvinylklorid (PVC).The present invention describes a cable comprising a layer of a polyethylene composition which is characterized in that it comprises. (A) from 5 percent to 95 percent, by weight of the total composition, of at least one first polymer which is an ethylene / α-olefin interpolymer having (i) a density of from 0.865 g / cm 3 to 0.95 g / cm 3; (ii) a molecular weight distribution (MJMJ of 1.8 to 3.5, (iii) a melt index ((2) from 0.001 g / 10 min to 10 g / 10 min) and (iv) a CBDI value greater than 50 percent, (B) from 5 percent to 95 percent, by weight of the total composition, of at least one other polymer which is a heterogeneously branched ethylene polymer or homogeneously branched ethylene homopolymer with a density of 0.9 g / cm 3 to 0.965 g / The cable of the present invention has superior mechanical properties and processability over conventional cables using current polymers such as low density polyethylene (LDPE), linear low density polyethylene (LLDPE) and polyvinyl chloride (PVC).
