On-Line Measurement of Rheological Properties of LDPE, HDPE and LDPE/MICA Systems in Single-Screw Extrusion

Abstract:

The quality of extrudate is closely related to its rheological properties during extrusion. Therefore, on-line measurement of rheological properties of polymer is important in extrusion process. In the present work, comparisons between the on-line viscosities of LDPE in single screw extruder and that in lab under the same condition were made by using online rheometer. Effects of set temperature of on-line rheometer, screw configuration and different positions, as well as weight proportions of filler, size of MICA particles of LDPE/MICA multiphase system on the melt viscosity in single screw extrusion are discussed.
