The melt flow index tester is one of the most helpful instruments in the plastics and polymer industry. The robust instrument can measure the resistance to the flow of material. Varying types of polymer melt at a particular temperature. The melt flow index test is conducted under a pre-determined force for a definite time. It is a quick test that can provide manufacturers with valuable information about the flowability of a polymer material. It can provide crucial insights for manufacturers and quality control professionals in various industries. Integrating this instrument within the production line can help optimize the process and ensure zero product failure.
Melt Flow Index Test
The melt flow index test is vital for polymers because it measures the flowability of a polymer melt. The MFI test is conducted by heating a polymer sample to its melting point and forcing it through a small orifice under a constant load. The amount of polymer that flows through the orifice in a given time is measured and reported as the MFI. The MFI test is essential for the characterization and quality control of polymers. Pacorr supplies state-of-the-art, user-friendly testing instruments that are designed in compliance with international standards.
The MFI test is essential for numerous reasons. Primarily, it can be used to determine the viscosity of a polymer type. Viscosity is vital to explore the polymer's processing capabilities and end-use properties. For example, the density of a polymer melt will affect its ability to be moulded or extruded.
It can be used to compare the flowability of different grades of the same polymer. This information can be used to select the grade of polymer best suited for a particular application.
The MFI test can be used to monitor the quality of a polymer product. If the MFI of a polymer product changes, it may indicate that the polymer has been contaminated or that its molecular weight has changed.
How Does Melt Flow Index Tester Function:
The standard test method for measuring the flowability of thermoplastic materials requires MFI or melt flow index testing instrument. The MFI test is used in various industries, including plastics, cosmetics, pharmaceuticals, food & beverages, etc. It is used to characterize and quality control thermoplastic materials, such as polyethylene, polypropylene, polyvinyl chloride, and nylon. Following are the steps that are typically involved in functionality of a melt flow index tester:
Step 1: Clean and contamination-free polymer samples, preferably in the form of small granules, are carefully placed in an enclosed heating chamber.
Step 2: The temperature of the heating chamber should be set to the polymer's melting point. Ensure the force sensor is placed above the sample to apply a constant force to the piston.
Step 3: A digital scale should measure the amount of polymer that flows through the orifice in a given time. The MFI can be calculated by dividing the weight of the polymer that flowed through the orifice by the time it took to flow.
