Melt index: The mass or volume of the thermoplastic material passing through a standard die every 10 minutes at a certain temperature and pressure, expressed in g/10min or ml/10min.

Common parameters:

Melt Index (MFI: Melt Flow Index)

Melt Index (MI: Melt Index)

Melt Flow Rate (MFR: Melt Flow Rate)

Scope of application

It is suitable for the determination of the melt mass flow rate of general thermoplastics, but at the same time it is not suitable for thermoplastics whose rheological behavior is affected by hydrolysis, polycondensation or crosslinking.
