{MFI} Know The Benefits Of The Unique Melt Flow Index Tester
The Melt Flow Index (MFI) Tester is a critical instrument in the plastics industry, offering insights into the melt flow characteristics of thermoplastic polymers. This article aims to address frequently asked questions about the Melt Flow Index Tester, helping you understand its importance, operation, and applications.
The Melt Flow Index Tester measures the rate at which a thermoplastic polymer melts and flows at a specific temperature and under a defined load.
An Melt Flow Index Testerheats a sample of the polymer to a specified temperature. Once melted, a piston exerts a force (through a specified weight) onto the polymer, pushing it through a die. The amount of material extruded in 10 minutes is measured in grams, representing the Melt Flow Rate (MFR).
Lower Melt Flow Index Testervalues indicate higher viscosity and less fluidity, suitable for applications requiring material strength and rigidity. Conversely, higher MFI values suggest lower viscosity and more fluidity, ideal for processes like film extrusion where ease of flow is necessary.
