Extrusion plastometers are used to characterize the flow behavior of thermoplastics. The melt mass 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.
The MFR/MVR tester can be operated alone or via WIN-MFR/MVR software. The active device status is intuitively displayed via the touch panel. The optional PC connection offers extended device configuration and measurement data management. The operating button allows glove-friendly command input in the respective operating step. The device can be upgraded in modules from the minimally instrumented standard MFR equipment, e.g., by connecting a scale, displacement sensors up to a lifting platform for automatic MFR/MVR testing.
