Melt Flow Index Tester The Smart Solution for Polymer Flow Testing

The Melt Flow Index Tester is a critical instrument that allows manufacturers to measure and control this behavior with precision.

At Pacorr Testing Instruments, we provide dependable testing solutions tailored to the needs of plastic and polymer industries. Our Melt Flow Index Tester is engineered for accurate, consistent, and easy melt flow rate analysis—giving you complete control over your raw materials.

What is a Melt Flow Index Tester?

A Melt Flow Index Tester (MFI Tester) determines the flow rate of thermoplastic materials by measuring how much molten polymer passes through a die over a standard period—usually 10 minutes—under a specific load and temperature. The result, called the Melt Flow Index (MFI) or Melt Flow Rate (MFR), is expressed in grams per 10 minutes.

This test provides valuable insight into the viscosity and processability of a plastic material, helping manufacturers choose the right material for their production processes and verify consistency across batches.

Why MFI Testing is Crucial

1. Consistency in Material Behavior

Material properties can vary from batch to batch, even with the same supplier. MFI testing helps verify that the material will perform consistently on the production line, preventing costly issues like uneven molding or poor part quality.

2. Process Optimization

Knowing the melt flow rate of a material allows process engineers to fine-tune their machinery. Adjusting temperatures, pressures, and cycle times based on MFI data can significantly enhance productivity.

3. Material Selection Confidence

Whether you're sourcing new materials or developing a product that requires specific flow characteristics, the MFI helps in making informed material choices that match your application requirements.

4. Validation of Recycled Content

As recycled materials become more common in production, manufacturers need to ensure blends perform to standard. MFI testing allows you to compare recycled plastics with virgin grades and make adjustments accordingly.

5. Meets Global Standards

MFI testing is widely recognized and required under international quality control standards like ASTM D1238 and ISO 1133. Using a certified MFI tester ensures compliance and boosts customer confidence.
