POLYETHYLENE FOR THE PRODUCTION OF OPEN HEAD DRUMS

摘要

The invention is directed to a pelletized ethylene polymer having: ° a density = 953 kg/m3 and 3 ( according to ISO1183) ° a high-load melt index (HLMI) > 3 g/10 min and = 12 g/10 min (according to ISO 1133; 190°C,21.6 kg) ° an Izod impact strength(-30°C) > 25 KJ/m2 and 2 (according to ISO 180/A) ° a strain hardening modulus > 10 and < 25 MPa (according to the method as described in Elsevier, Polymer 46(2005) 6369- 6379) and ° Mw / Mn = 8 and < 16 (according to size exclusion chromatography (SEC) measurement). The polyethylene can be applied in the production of open head drums and jerry cans.
