Extrudate swell of HDPE melts: I. Experimental

•Develop a reliable experimental set up to measure the extrudate profile (swell).•Study the effects of geometrical parameters of the die on extrudate swell.•Study the effect of MW and MWD of a series of HDPEs on extrudate swell.•Develop an analytical model to assess the effect of surface tension on...
