extension of capillary rheometer

A well-known problem in polymer extrusion are flow instabilities resulting in unsuable products with rough surface structure. In cooperation with Goettfert we integrated high sensitive pressure detectors in the dye of capillary rheometer. These extremely fast and sensitive detectors allows now the detection and the identification of different flow instabilities and therefore an optimized workflow in polymer production prozesses.
