Melt Flow Index Tester

What is a Melt Flow Index Tester?

A Melt Flow Index Tester measures the amount of molten polymer that flows through a standard capillary die within a fixed time. This value is commonly used to understand the flow properties of plastic materials. A higher MFI value usually indicates easier flow, while a lower value indicates higher viscosity.

For plastic manufacturers, compounders, packaging companies and polymer testing laboratories, MFI testing is important because it helps verify whether a material is suitable for injection molding, blow molding, extrusion or other processing applications.
