Computerized Melt Flow Index Tester (Test Method A & B)

As per ASTM D 1238 & ISO 1133 - (Test Method A & B) to check the melt flow rate (MFR), melt volume rate (MVR) & melt density of thermoplastics and compounds with automatic result.

The Computerized Melt Flow Index Tester (Test Method A & B) is the flagship instrument in our MFI range. It is a fully automatic, microcontroller-based, PC-interfaced tester that determines three critical melt flow properties — Melt Flow Rate (MFR in g/10 min), Melt Volume Rate (MVR in cu.cm/10 min) and Melt Density (g/cu.cm) — in a single test, in full compliance with ASTM D 1238 and ISO 1133 Test Methods A and B.

This model is designed for laboratories that test a wide range of polymers, including high-MFI grades above 50 g/10 min where Test Method A becomes unreliable. Test Method B uses linear displacement measurement of the piston to derive MVR directly, while the built-in weighing scale derives melt density from the same test. The combined output of MFR, MVR and Melt Density gives a complete rheological fingerprint of the polymer sample.

With auto loading of weights, auto cutting of flow extrudate, auto weighing of the extrudate and software-driven result calculation, the instrument is virtually hands-free. It is the recommended model for export-oriented polymer producers, R&D laboratories and contract testing houses that need to satisfy international QC audits.
