Melt index tester MFR and MVR

Extrusion plastometers - accurate measurement of MFR and MVR of plastic materials
ZwickRoell's extrusion plastometers, available through ZRS Testing Systems, are used for reliable characterization of the plastic materials flow properties in the molten state. By measuring the melt flow rate, melt flow rate index (MFR) and melt volume flow rate (MVR), you get crucial data for quality control, material selection and optimization of processing parameters.

Melt flow index measurement is used, for example, in:

• Input control of raw materials

• Comparisons between different polymer grades

• Ensuring process stability in manufacturing

Test equipment for all needs
Needs vary depending on where in the plastics process the measurement takes place. That's why we offer the right solution for every test volume - from compact entry-level models for fast MFR monitoring, to modular systems for advanced MFR and MVR measurements with high repeatability and precision.

The systems are easy to use, quick to clean and meet all relevant standards (e.g. ISO 1133 and ASTM D1238). Integrated functions for weight, time, temperature and force ensure stable and comparable results - every time.

With ZRS you also get advice, service and calibration to keep your test flow both reliable and cost-effective.
