Melt Flow Index Tester

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.

  • Stand alone or WIN-MFR/MVR software operation
  • Upgradeable from basic up to MFR/MVR-Automat
  • Cleaning piston and Extrudate Cutter: manual or motor-driven
  • Compatible with standards: ISO 1133, ASTM D 1238, ASTM D 3364, JIS K 7210
