The melt flow index (MFI) is a crucial parameter in the analysis and quality control of polymers, as it measures the ease with which a polymer melts and flows under specific conditions. This property of polymers can be tested with the help of a specialized instrument that accurately measures both the weight and volume of molten polymer that passes through a standardized capillary orifice within a given time frame. By obtaining precise melt flow index values, manufacturers can evaluate various properties such as viscosity, molecular weight distribution, processability, and potential applications of different polymers. Presto is a Asia’s No.1 melt flow index tester manufacturer and designs different models of this quality testing equipment. The melt flow deluxe model is highly useful in plastic and polymer industry to determine the flow rate of different polymers. In this article, we will focus on the specific MFI formula for calculating melt flow index of polymers. But first, let us focus on the principle of melt flow index testing.
