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.
Compatible with standards: ISO 1133, ASTM D 1238, ASTM D 3364, JIS K 7210
