The ease with which a thermoplastic polymer melt flows is gauged by the Melt Flow Index Tester (MFI). It is defined as the amount of polymer, measured in grammes, that flows in ten minutes through a capillary with a particular diameter and length under pressure from different gravimetric weights at different temperatures. The value of MFI is typically correlated by polymer processors with the grade of polymer that they must select for various processes, and most frequently, this value is not accompanied by the units because it is assumed to be g/10min.
