mi40
The new generation of melt flow index testing is embodied by
the mi40 from GÖTTFERT. Operators in incoming goods
inspection and quality control (QC) benefit from automated
and more precise determination of MFR (Melt Flow Rate)
and MVR (Melt Volume Rate) according to ASTM D1238 and
ISO 1133 (Procedures A-B-C-D).
With force-controlled compression of up to 80 kg, the
comparability of melt flow index measurements is
significantly improved. In addition, the mi40 enables
multi-load tests with up to eight different weights, which
can be applied in ascending, descending or freely selectable
sequences.
An automated operating point detection further optimizes
the measuring process. This makes the mi40 a weight-step
testing instrument comparable to a rheometer.
Cleaning of the test barrel is simplified by a freely accessible,
swiveling barrel and a side-mounted, semi-automated
cleaning module.

Add-on “visco” for advanced viscosity measurements
10
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.
