Polyethylene molding composition with multimodal molecular weight distribution, used for making blow-molded cans, contains low-molecular homo polyethylene and high- and ultrahigh-molecular co polyethylenes

摘要

Polyethylene molding composition with multimodal molecular weight distribution has a density of 0.953-0.955 g/cm3 at 23degreesC and a melt flow index MFI190/5 of 0.50-0.65 dg/minute and contains (wt.%) 40-50% low-molecular ethylene homopolymer A, 25-35% high-molecular ethylene copolymer B with another 4-8 carbon (C) olefin and 24-28% ultrahigh molecular ethylene copolymer C. An Independent claim is also included for production of the molding composition.
