What is Melt Flow Index (MFI)?

The Melt Flow Index (MFI) is a measure of the ease of flow of the melt of a thermoplastic polymer. It is a crucial parameter that indicates the viscosity of the polymer in its molten state. MFI is expressed in grams per 10 minutes and is determined by measuring the amount of polymer that flows through a capillary of specific dimensions under a defined load and temperature.

Why is MFI Important?

Quality Control:  Melt Flow Index Testing helps in maintaining consistent quality in polymer production. By regularly measuring MFI, manufacturers can ensure that the polymer’s properties remain within specified limits.

Process Optimization: Knowing the MFI of a polymer helps in optimizing processing conditions such as temperature and pressure in extrusion and melding operations. This leads to efficient production and minimizes defects.

Material Selection: MFI provides valuable information for selecting the appropriate polymer grade for specific applications. Different applications require polymers with different flow characteristics, and MFI testing ensures the right match.

Predicting Performance: MFI can be an indicator of a polymer’s performance in its end-use application. For instance, a high MFI indicates lower molecular weight and higher fluidity, which might be suitable for thin-walled products, whereas a low MFI suggests higher molecular weight and better mechanical properties.
