The mi40 Visco is designed to perform measurements based on the ISO 11443 standard, which is commonly
used for capillary rheometers. It has additional capabilities that allow it to perform viscosity tests
as easily as standardized melt flow index tests. During the “visco” test mode, the mi40 instrument uses
the integrated motor to push the piston at constant defined speeds. The resulting pressure is measured
with a force transducer in the piston holder.
Compared to normal MFR-measurements, it is possible to reach higher shear rates which are more relevant
for actual production processes. Therefore, viscosity tests by this GÖTTFERT Plastometer are more like
a processability test compared to the standard MFR test.
