Melt Flow Index Tester: Basics, Applications, and Quality Control Role

4 minutes, 1 second Read

The melt flow index tester, referred to as the MFI tester, is a notably valuable testing tool utilized in both the plastic and polymer industry. This exceptional device plays a crucial role in assessing the material flow resistance of substances like polymers that experience melting at particular temperatures. In the following exploration, we will delve into the basics of MFI, its significance, measurement techniques, instrumentation, factors influencing results, applications in quality control, considerations for polymer selection and design, as well as challenges and limitations.

MFI is a specialized tool within the realm of plastics, shedding light on the behavior of plastics during their production. As a crucial parameter and with the assistance of an MFI tester supplier in UAE, it aids in understanding the flow properties of plastics, akin to uncovering the superhero powers of MFI!

 Why is MFI Important?

MFI holds value for multiple reasons. It influences the molding and extrusion behavior of plastics, with higher MFI values indicating lower viscosity and faster flow rates. However, excessively high MFI can lead to issues like sagging and compromised mechanical properties. Moreover, MFI serves as an indicator of polymer molecular weight and distribution, contributing to strength, toughness, and heat resistance. It also functions as a quality control tool, monitoring the consistency and reliability of plastic during production and storage.

 How to Measure MFI?

MFI is measured using a melt flow indexer or extrusion plastometer. This device contains adie, a heated barrel and a piston.  In this process, a mass of plastic is subjected to heat and pressure, and the molten plastic is forced through the die. The amount of plastic flowing out in 10 minutes is recorded as the MFI value. ISO 1133 and ASTM D1238 are widely adopted standards for measurement, where MFR and MVR are denoted in grams per 10 minutes (g/10 min) and cubic centimeters per 10 minutes (cm^3/10 min), respectively.


In-depth explanations of the components and functionality of MFI testing equipment offer a thorough understanding of the technology underpinning MFI measurements. The article delves into different categories of MFI testing machines, spanning from m

Factors Affecting MFI

This section dissects key factors influencing MFI results, including temperature, polymer molecular weight, and pressure. By unraveling these variables, the article equips readers with a profound understanding of the nuanced dynamics shaping MFI measurements.

Applications in Quality Control

MFI is integral to quality control in polymer production, ensuring consistency and detecting batch-to-batch variations. Real-world examples and case studies illustrate how MFI serves as a reliable tool for maintaining high standards in the manufacturing process.

Polymer Selection and Design

The article delves into the role of MFI in polymer selection and design, outlining its pivotal role in choosing materials for specific applications. Design considerations based on MFI values provide valuable insights for engineers and researchers seeking optimal performance in their products.


Challenges and Limitations

The article concludes by addressing common challenges encountered in MFI testing and offering insights into overcoming these obstacles. It also highlights the limitations of MFI as a predictive tool for polymer behavior, providing a balanced perspective on its capabilities and areas for improvement.

Furthermore, the conclusion sheds light on the limitations inherent in using MFI as a predictive tool for polymer behavior.While MFI provides valuable information, the article underscores the importance of maintaining a balanced perspective on its capabilities and areas for improvement. By acknowledging its limitations, the industry can make informed decisions about incorporating MFI results into quality control processes. Overall, the conclusion serves as a comprehensive reflection on the complexities associated with MFI testing, fostering a nuanced understanding of its role in polymer analysis and quality control practices.


MFI (melt flow index) and MVR (melt volume flow rate) are methods for measuring the ease of flow of molten plastic. MFI is measured in weight (grams per 10 minutes), while MVR is measured in volume (cubic centimeters per 10 minutes). To get the MFI from the MVR, you multiply the water level. It is important to know the moisture content of the plastic, which may vary permanently on the data sheet.

Specifically, if you want to determine the molding velocity of molded plastic, you need to understand both MFI and MVR. These measurements are internationally standardized through ASTM D1238 and ISO 1133. Remember, older units of MFIs do not meet the revised ISO 1133 standard introduced in 2011.

MFI emerges as a crucial parameter defining the flow characteristics and molecular weight of thermoplastic materials. It actively contributes to raw material selection, production technology optimization, and product quality assurance. However, prudent use of MFI is essential to maximize its assistance in production processes and daily applications.
