POLYETHYLENE FOR THE PRODUCTION OF INTERMEDIATE BULK CONTAINERS

摘要

The invention is directed to an ethylene copolymer having: ° a high-load melt index (HLMI) is = 3 g/10 min and is =10 g/10 min (according to ISO 1133) ° Mw / Mn = 14 and = 25 (according to size exclusion chromatography (SEC) measurement) ° a density = 945 kg/m3 and = 955 kg/m3 ( according to ISO 1183) and ° an Izod impact strength (-30°C) = 10 KJ/m2 and = 50 KJ/m2 (according to ISO 180/A). The strain hardening modulus of HDPE = 20 and = 40 (according to the method as described in Elsevier, Polymer 46(2005) 6369-6379). The polyethylene is applied in the production of industrial bulk containers and fuel tanks.
