In the plastics industry, where precision and performance go hand in hand, understanding your material's behavior is critical. One of the most trusted tools for evaluating polymer flow characteristics is the Melt Flow Index Tester (MFI Tester). At Pacorr.com, we provide top-tier MFI testers that help manufacturers stay ahead in quality control and product consistency.

What Is a Melt Flow Index Tester?

The Melt Flow Index Tester is used to determine how easily a thermoplastic polymer melts and flows under specific temperature and pressure conditions. The result is known as the Melt Flow Index (MFI)—a key indicator of the material’s viscosity, processability, and molecular structure.

Why Is MFI Testing So Important?

Every polymer reacts differently when subjected to heat and pressure. The MFI value helps manufacturers:

  • Select the right material for specific applications

  • Ensure uniform processing during molding or extrusion

  • Identify material inconsistencies or quality issues

  • Comply with global testing standards like ASTM D1238 and ISO 1133

In short, MFI testing allows you to understand the "flow personality" of your plastic.

Where Is It Used?

The MFI Tester is a vital part of quality control across a wide range of industries, including:

  • Plastic product manufacturing

  • Automotive and aerospace

  • Medical device production

  • Food and consumer packaging

  • Electronics and home appliances

When accuracy matters, so does having the right testing equipment.
