Hands-on processing control
The add-on “visco” extends our melt index tester mi40 so that viscosity measurements according to the capillary rheometer standard ISO 11443 are possible.

Melt index testers are used as standard to determine the MFR (melt flow rate) or MVR (melt volume rate) of pellets, powders and fine granules. Until now, a capillary rheometer was required for measurements according to ISO 11443 – a method that is more complex and more demanding to operate.

With the add-on “visco”, measurements can be made directly on the plastometer.
Higher shear rates are achieved than with conventional MFR measurements, which enables a more realistic representation of the actual processes. This makes viscosity testing with the mi40 a practical process control – far beyond a classic melt flow index test.
