MFR and MVR Melt Flow Index Testers

Extrusion Plastometers – Precise Measurement of MFR and MVR for Plastic Materials
ZwickRoell's extrusion plastometers, available through ZRS Testing Systems, are used for the reliable characterization of plastic materials' flow properties in the molten state. By measuring the melt flow rate, melt flow index (MFR), and melt volume flow rate (MVR), you obtain critical data for quality control, material selection, and the optimization of processing parameters.

Melt flow index testing is used, among other things, in:

• Incoming Inspection of Raw Materials

• Comparisons Between Different Polymer Grades

• Ensuring Process Stability in Manufacturing

Test equipment for every need
Requirements vary depending on where in the plastic processing cycle the measurement is taken. That is why we offer the right solution for every test volume—from Compact entry-level models for rapid 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 comply with 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 consulting, service, and calibration to keep your testing workflow both reliable and cost-effective.
