What is a Melt Flow Index Tester?

A  Melt Flow Index Testing is a specialized instrument used to measure the rate at which a polymer melts and flows under specified conditions of temperature and pressure. This measurement, expressed in grams per 10 minutes, is crucial for assessing the quality and suitability of plastics for various applications. The MFI value provides insight into how a polymer will behave during processing and in its final application.

How Does the Melt Flow Index Tester Work?

The operation of a  Melt Flow Index Testing involves several steps:

• Sample Preparation: A specific amount of polymer sample is preheated in the tester’s barrel.

• Melting: The sample is melted at a predetermined temperature.

• Extrusion: A standard weight is applied to the molten polymer, forcing it through a capillary die.

• Measurement: The extrudate is collected over a specified time interval, and its mass is measured to calculate the MFI.
