Abstract

We have used a temperature sensitive fluorescent dye, doped into polycarbonate, to monitor the true resin temperature during extrusion processing. The fluorescent dye, perylene, was doped into the polycarbonate at very low concentration. We apply this measurement concept to extrusion processing by using an optical sensor that accesses the machine at standard instrumentation ports. The sensor has a confocal optics design that permits the measurement of temperature profiles. With the sensor looking over the screw of a single extruder, temperature profiles from the barrel wall to the core of the screw were obtained as a function of screw rpm, screw design and melt flow index.
