1. Product description

The polymer melt is a pseudoplastic fluid with the flow characteristics of shear thinning. The relationship between its viscosity and the shear rate constitutes the general viscosity. Viscosity can fully characterize the fluidity of polymer melt, and the processing characteristics of polymer depend on its flow behavior

The extrusion capillary rheometer can be used to measure the viscosity of the polymer melt. The basic principle is to use an appropriate method to make the polymer melt flow stably from a capillary. In this process, measure the pressure drop generated when the melt flows through the capillary tube and the outflow per unit time at the same time, and then perform the appropriate calculation on these measured values to obtain the general viscosity.

There are two ways to make the polymer melt pass through the capillary tube, one is to use a piston to advance, the other is to use a screw to extrude. Screw extrusion measurement is closer to the extrusion processing environment, especially for materials that must undergo strong shear to form a uniform melt (such as a mixture of several materials)

1)Select an internationally renowned brand (GEFRAN) melt pressure sensor, with high test data accuracy

2)Select a capillary mold to test the apparent viscosity curve of materials

3)Selecting Capillary Moulds with Different Length to Diameter Ratios to Test the Real Viscosity Curve of Materials

4)Optional narrow slit die for testing the rheological curve of materials under special flow fields

5)Optional laser diameter gauge can be configured to record the diameter of the extrusion in real time and study the extrusion swell behavior of the material
