Test conditions Melt Flow Index Test
The determination of the Melt Flow Fate [MFR / MVR] is carried out according to the standardized ISO1133 and ASTM D1238 test methods. Polymer melts are melted in a...
Determination of Melt Flow Index (MFR and MVR)
The melt flow index is a standardized test method to determine the flow rate of plastics at a defined temperature and constant force. The test method...
MFR-Standards: ISO 1133 and ASTM D1238
The determination of the melt flow rate (MFR) and the melt volume rate (MVR) is described in various international standards...
Intrinsic Viscosity
The intrinsic viscosity (IV), also referred as intrinsic viscosity, or Staudinger index [η]...
MFR/MVR: Common Terms
Over the years, quite a number of different terms have become established in the field of melt flow measurements, often with the same or similar meanings. This sometimes leads to misunderstandings and the whole subject area seems more complicated than it actually is...
mi40 visco: Viscosity measurements on a plastometer
With the add-on "viscosity measurement" the mi40 is transformed into a mi40 visco. This enables the plastometer to perform viscosity measurements according to the standard for capillary rheometers ISO 11443...
Multi-Load-Measurements
Both our mi40 and MI-ROBO 89.16 can perform automated multi-load measurements with only one filling of...
Melt Flow Indexer (MFR/MVR) vs. Capillary Rheometer
A Capillary Rheometer as well as a Melt Flow Indexer (Plastometer) can compare the flow behaviour of polymer plastics...
Better than ISO 1133
All our melt index testers are equipped with a fast and precise temperature control...
Reproducible and Accuracy of Melt-Index-Tests
GÖTTFERT Melt Flow Testers (Plastometers) are manufactured according to the most modern electronic and mechanical standards with minimal manufacturing tolerances. The result is a testing device which delivers precise and accurate MVR and MFR test results.
