The pullout capability of polymer melts is of interest in many plastic manufacturing and processing processes. In addition to the patented RHEOTENS process, the GÖTTFERT portfolio also offers a HAUL-OFF system which is suitable for higher take-off speeds. In addition to these systems, which are fed by a laboratory extruder or a capillary rheometer, the D-Melt offers the possibility of testing polymers for elongation at very low shear rates as part of quality control.
