Abstract
Method of compounding a multimodal polyethylene composition in a compounding device, wherein a) the total residence time of the polyethylene composition in the compounding device is at least 1.5 minutes, b) the total drive specific energy (SEC) applied on the polyethylene composition is from 0.270 to 0.460 kWh/kg, c) optionally, a specific cooling energy (SCC) of at most 0.200 kWh/kg is applied on the polyethylene composition, d) the total specific energy, which is the difference between the total drive specific energy SEC and any specific cooling energy SCC, applied on the polyethylene composition is from 0.220 to 0.330 kWh/kg.
