More Information
Summary:A polyethylene composition comprising at least a first composition and a second composition in amounts of at least 70 wt% of the first composition which comprises at least: (A) up to 60 wt% lower molecular weight (LMW) polyethylene homo or copolymer obtained by Ziegler-Natta catalysis having a density of at least 940 kg/m3; and (B) up to 60 wt% higher molecular weight (HMW) polyethylene homo or copolymer obtained by Ziegler-Natta catalysis and having lower density than component (A); and up to 30 wt% of the second composition which comprises at least: (C) a polyethylene homo or copolymer obtained by single site catalysis (SSC) and having a density of up to 980 kg/m3, wherein said polyethylene composition has a density at least of 925 kg/m3.
