Melt Flow Index Testers (Plastometers) are commonly used
to determine the Melt Flow Rate (MFR) or the Melt Volume
Rate (MVR) of plastic pellets, powders and granules. These
instruments are designed in compliance with the relevant
standards ISO 1133 and ASTM D1238.
Until now, viscosity measurements according to ISO 11443
required the use of a Capillary Rheometer. Compared to a
plastometer, a Capillary Rheometer is more time consuming
and more demanding in terms of operation.
With the Add-On “visco” for the melt flow index tester mi40,
viscosity measurements can now also be carried out with
a plastometer. In contrast to standard MFR measurements,
significantly higher shear rates can be achieved – a decisive
factor for simulating actual processing conditions.
Thus, viscosity testing with this GÖTTFERT plastometer is
closer to processability control than to a conventional
melt flow index test.
