The Melt Flow Index (MFI) is a measure of the flow rate of a polymer melt at a standard temperature and a standard load, in conformity with ISO Standard 1133. The MFI correlates inversely with the molecular weight of the material – a high MFI suggests lower molecular weight. This relationship helps to determine the strength and flow behavior of polymers, and guiding decisions in manufacturing processes like injection molding and extrusion. To gain more insight into the viscosity and flow behavior of a polymer, a rheometer can be used.
