Abstract: The invention relates to a polyethylene composition with multi-modal molecular mass distribution, which is particularly suitable for blow molding of small containers with a volume in the range of from 200 to 5000 cm3 (=ml). The composition has a density in the range of from 0.955 to 0.960 g/cm3 at 23° C. and an MFR190/5 in the range from 0.8 to 1.6 dg/min. It composition from 45 to 55% by weight of a low-molecular-mass ethylene homopolymer A, from 20 to 35% by weight of a high-molecular-mass copolymer B made from ethylene and from another 1-olefin having from 4 to 8 carbon atoms, and from 20 to 30% by weight of an ultrahigh-molecular-mass ethylene copolymer C.

Abstract: The invention relates to a polyethylene composition with multimodal molecular mass distribution, which is particularly suitable for the blow molding of large containers with a volume in the range of from 10 to 150 dm3 (I). The composition has a density in the range of from 0.949 to 0.955 g/cm3 at 23° C. and an MFI190/5 in the range of from 0.1 to 0.3 dg/min. It comprises from 38 to 45% by weight of a low-molecular-mass ethylene homopolymer A, from 30 to 40% by weight of a high-molecular-mass copolymer B made from ethylene and from another 1-olefin having from 4 to 8 carbon atoms, and from 18 to 26% by weight of an ultrahigh-molecular-mass ethylene copolymer C.

Abstract: The invention relates to a polyethylene composition with multimodal molecular mass distribution, which is particularly suitable for the blow molding of L-ring drums having a volume in the range of from 50 to 250 dm3 (I). The composition has a density in the range of from 0.950 to 0.956 g/cm3 at 23° C. and a MFR1gp/21.6 in the range from 1.5 to 3.5 dg/min. It comprises from 35 to 45% by weight of a low-molecular-mass ethylene homopolymer A, from 34 to 44% by weight of a high-molecular-mass copolymer B made from ethylene and from another 1-olefin having from 4 to 8 carbon atoms, and from 18 to 26 % by weight of an ultrahigh-molecular-mass ethylene copolymer C.
