POLYETHYLENE COMPOSITION HAVING HIGH MECHANICAL PROPERTIES AND PROCESSABILITY

摘要

A polyethylene composition particularly suited for producing pipes and films, having the following features: 1) density from 0.945 to 0.955 g/cm3, determined according to ISO 1183 at 23°C; 2) ratio MIF/MIP from 23 to 40; 3) MIF from 8.5 to 18 g/10 min.; 4) HMWcopo index from 3.5 to 20; 5) long-chain branching index, LCBI, equal to or greater than 0.45.
