Low melt flow index adhesives have better properties but are more difficult to apply.

Melt flow index, a value inversely proportional to the molecular weight of the base polymer.

High melt flow index adhesives are easy to apply but have poor mechanical properties due to short polymer chains.

Melt flow index or MFI is a measure of the ease of flow of the melt of a thermoplastic polymer.

The melt flow rate (MFR) or melt flow index (MFI) is a measure of molecular weight of polypropylene.

Synonyms of Melt Flow Index are Melt Flow Rate and Melt Index.
