Melt Flow Tester - Melt Flow Indexer - MFI

Melt Flow Indexers, also known as Melt Flow Testers or MFI Testers, are essential for evaluating the flow properties of thermoplastic materials under controlled conditions. These instruments measure the melt mass-flow rate (MFR), melt volume-flow rate (MVR), and melt density, providing critical insights into material behavior during processing.

They are widely used to test a variety of thermoplastic raw materials, including polycarbonate, fluoroplastics, polyethylene, polypropylene, ABS, POM, and more. By determining viscosity and flow characteristics, Melt Flow Indexers help manufacturers ensure consistency, optimize processing parameters, and maintain compliance with industry standards.
