Work Process of Melt Flow Index Tester

1. Source of Info: https://www.perfectgroupindia.co.in/blog/work-process-of-melt-flow-index-tester Work Process of Melt Flow Index Tester Introduction Under specific requirements a Melt Flow Index Tester measures the flow rate of molten polymer. The tester is used to load a sample, which is then heated to a specified temperature and melting. After that a piston applies pressure to push the molten polymer through a die. A measurement of the amount of polymer extruded in just ten minutes is called the Melt Flow Index. By displaying the thickness of the polymer this measurement helps manufacturers for calculating its suitability for a range of use and processing ability. Understanding Melt Flow Index Tester The flow characteristics of thermoplastic materials can be measured in a lab setting using a Melt Flow Index Tester. It analyzes the volume of polymer that passes through a die of a given size while the temperature and pressure are controlled. The thickness of the material is displayed by the flow rate which is measured in grams per 10 minutes. While a low MFI represents a greater density which makes the polymer more difficult to flow and process, a high MFI represents a lower density which makes the polymer easier to process.

2. Polymer manufacturers depend on the testing equipment for projecting the behavior of materials during injection molding, extrusion and blow molding processes. Also it plays an important part in quality control by verifying that the polymer grades match client and industry requirements. Work of a Melt Flow Index Tester To guarantee accurate and dependable measurements a Tester must follow a number of exact processes. This is an explanation of the tester's workflow in detail: 1. Sample Preparation In order to use a Melt Flow Index Tester the polymer sample has to be processed. The sample usually takes the shape of powder or small grains. After the testing instrument barrel has been preheated to a certain temperature the polymer material is loaded into it. Because the flow behavior of the polymer changes greatly with temperature the test temperature is very important. The range of temperatures used for standard testing is between 190°C and 300°C, depending on the kind of polymer being examined. 2. Heating the Polymer The tester heats the barrel to the required temperature once the sample is loaded. In order to allow the polymer to melt and reach a stable accuracy this temperature is maintained for a specific duration of time. When the polymer is heated it is guaranteed to be molten and prepared for ejection. 3. Applying Pressure The molten polymer is placed under pressure using a piston during heating. The material is forced by the pressure through a die with a specific area size. The pressure conditions that the material would face during processing in actual uses such as extrusion or injection molding are recreated in this step. 4. Measurement of Flow The measurement of the amount of polymer that flows through the die under the pressure that is used over a specific period of time which is usually 10 minutes is the most important part of the Melt Flow Index tester. Taking measurements and recording the amount of polymer blown is

3. done. This outcome is known as the Melt Flow Index, and it is measured in grams per 10 minutes. The MFI and polymer molecular weight are deeply connected. Because of their easier flow the polymers with lower molecular weights usually have higher MFI values. On the other hand, because large molecular weight polymers are more thick and have a harder time flowing they have lower MFI values. 5. Multiple Test Conditions The test can be performed with different weights or at different temperatures for more accurate findings. This gives an improved understanding of the polymer processing ability by helping with understanding how it behaves under different conditions.
