Capillary rheometry has its origins in polymer melt processing, but is also directly relevant to many other material processes such as high speed coating and printing applications. Based on controlled extrusion of a test material, capillary rheometry enables material flow and deformation properties to be characterized under conditions of high force (or pressure), high shear rate and at elevated temperature.
The basics of the capillary rheometry technique are as follows:
Capillary rheometry also enables other rheological and process characteristics to be evaluated, including die swell, melt fracture, wall slip, flow/no-flow stress, melt strength, haul off and pVT relationships.
