Temperature Monitoring of Capillary Rheometry Using a Fluorescence Technique

Abstract

A non-contact temperature monitoring technique based on fluorescence spectroscopy was used to measure the temperature of a polymer resin during capillary rheometry testing. Polyethylene doped with a fluorescent dye, perylene, was used in experiments that were designed to measure resin temperature changes due to shear heating as shear rate in the capillary increased from 10 to 10000 s-1. Resin temperature at the exit orifice of a 1 mm diameter capillary die was found to increase monotonically with increasing strain rate reaching 25 oC above the capillary set point temperature at the highest shear rates. The implications regarding rheometry testing are discussed.
