What is a Melt Flow Index Tester?
The Melt Flow Index Tester (MFI Tester) measures the flow rate of melted thermoplastic resins. It works by applying a specific weight to a sample inside a heated barrel, forcing it through a small die. The amount of material extruded in 10 minutes is the melt flow index, expressed in grams per 10 minutes (g/10 min).
This value provides insight into the viscosity, molecular weight, and processability of the polymer—key factors in determining its performance in production.
Why is Melt Flow Testing Important?
Quality control teams use MFI testing to:
- ✅ Detect inconsistencies in raw material batches
- ✅ Compare polymer grades from different suppliers
- ✅ Adjust molding and extrusion parameters
- ✅ Maintain compliance with standards like ASTM D1238 and ISO 1133
With this data, manufacturers can make better decisions and prevent costly defects.
