Melt index

This test method is used to determine the melt mass flow rate and melt volume flow rate of polymers.

A polymer melt is extruded through a standard die under the influence of a defined force and temperature. The melt mass flow rate (MFR) and the melt volume flow rate (MVR) are respectively the mass or volume of this melt that is extruded in ten minutes.
