Abstract:
A polyethylene composition for producing blow-molded hollow articles, having the following features: 1) density from 0.948 to 0.952 g/cm3 determined according to ISO 1183-1 at 23° C.; 2) ratio MIF/MIP from 12 to 25; 3) MIF from 18 to 40 g/10 min.; 4) Mz equal to or greater than 1,200,000 g/mol; 5) η0.02 from 35,000 to 55,000 Pa·s; 6) long-chain branching index, LCBI, equal to or greater than 0.55; and 7) ratio (η0.02/1000)/LCBI from 55 to 75.
