The MFI is a measure of the flow rate of a polymer melt (expressed in grams per 10 minutes) at a standard temperature and a standard load, in conformity with ISO Standard 1133.

Measurements are carried out with a Karg MeltFlow Basic tester equipped with a range of loads.

An MFI measurement can be used to check if a material is on-spec with regards to the MFI specified in the data sheet. To gain more insight into the rheology of a polymer, a rheometer can be used. MFI in g/10 min
