Melt Flow Rate Testing
Melt flow rate (MFR) testing indicates how easily a polymer melt flows, helping match recyclate to injection-moulding or extrusion process windows.
Melt Flow Rate Testing
MFR (or melt flow index) measures the mass of polymer extruded through a standard die under set temperature and load. It is a practical indicator of molecular behaviour and processability, useful for grading and batch consistency.
How we handle it, step by step
Select the standard temperature and load for the polymer.
Dry and prepare the sample as required.
Record mass extruded over the standard interval.
Compare the result against target grade behaviour.

Melt Flow Rate Testing — questions we get
What does a high MFR mean?
Higher MFR indicates easier melt flow and generally lower molecular weight, suiting thin-wall, fast-fill parts.
Does recycling change MFR?
Reprocessing can shift MFR through chain scission or cross-linking, so batch testing supports consistency.
