METHOD FOR COMPOUNDING A MULTIMODAL POLYETHYLENE COMPOSITION

摘要

Method of compounding a multimodal polyethylene composition in a compounding device, wherein the total residence time of the polyethylene composition in the compounding device is at least 1 minute, the total drive specific energy (SEC) applied on the polyethylene composition is from 0.240 to 0.450 kWh/kg, and, optionally, a specific cooling energy (SCC) of at most 0.200 kWh/kg is applied on the polyethylene composition, such that the total specific energy, which is the difference between the total drive specific energy SEC and the specific cooling energy SCC, applied on the polyethylene composition is from 0.220 to 0.330 kWh/kg.
