What is melt flow index (MFI)?

The melt flow index (MFI) is a measure for the ease of flow of melted plastics. A sample of about 5 grams is heated by specified temperature and forced to flow through a capillary using a piston actuated by a specified weight. The weight of melt in grams flowing through the capillary in 10 minutes is the melt flow index.

Melt Flow Index Formula:

MFI (In Grams) = Weight of Melted samples in 10 minutes

Density of plastics polymers

Plastic Raw Material Shrinkage Dimensional Data

The shrinkage of plastics signifies the volume contraction of polymers during the cooling step of the processing of polymers. This contraction is partly due to the difference of density of polymers from the melt state and the cooled, rigid state.
