MFI-3322 Melt Flow Indexer

The Melt Flow Indexer is related to the melted material viscosity. It allows the operator to make an estimation of " mean molecular weight", at the same time gives an indication of "melt flow ability" through a die.

The melt index is defined as the weight or the volume of melted material flowing through a calibrated die, under the effect of a pre-determined force, at constant temperature and for the total time of 10 minutes.

Flow Rate Ratio (FRR)

Allow users to determine flow rate using two or three different test loads on one charge of material.
