Extrusion plastometers are used to characterize the flow behaviour of thermoplastics. They are suitable devices for MFI-measurement of meltmass flow rate (MFR) and melt-volume flow rate (MVR). The meltmass flow rate, MFR value (g/10min) indicates the amount of material flowing through a capillary with defined dimensions at a specific pressure and temperature in ten minutes. The melt-volume flow rate, MVR value (cm³/10min) indicates the volume that is pressed through a capillary in ten minutes.
Two models of these testers are available:
The basic model which is designed for manual testing for limited measuring demand and teaching.
The compact model which is ideal for high measuring comfort with automatic weight loading.
