POLYETHYLENE COMPOSITIONS HAVING IMPROVED TEAR PROPERTIES

摘要

Disclosed is a high density multimodal polyethylene composition that has a density of 0.935 g/cc or more, and that includes a blend of a first polyethylene component and a second polyethylene component, in which: the first polyethylene component includes a bimodal polyethylene; and the second polyethylene component includes a metallocene produced unimodal polyethylene, the composition characterized in having a low level of polyethylene having a molecular weight of less than 1,000 amu and a low level of polyethylene having a molecular weight greater than 500,000 amu.
