Abstract
Large blow moldings are made from polyethylene of density ρ≧0.94 g/cmand of melt flow rate MFR 190/21.6<50 g/10 min, and of notched tensile impact strength a(−30° C.) not less than 300 kJ/mand bursting strength, determined by a drop height test at −18° C., of more than 3 m. Processes for producing large blow moldings of this type involve annealing large blow moldings after production. The moldings are used for storage and transport of hazardous materials.
