The object of this work is to investigate the foaming characteristics of Metallocene-catalysed polyethylenes for rotational moulding. This paper reports on the results of ongoing experimental investigations in which rheological and thermal parameters are related to the polymer structure and mechanical properties of metallocene polyethylene foams. Through adjustments to moulding conditions, the significant processing and physical material parameters, which optimise metallocene polyethylene foam structure, have been identified. The results obtained from equivalent conventional grades of polyethylene (PE) are used as a basis for comparison.
