A melt flow index (MFI) tester is a laboratory instrument used to measure the flow properties of thermoplastic materials. It is commonly used in the plastics industry to determine the melt flow rate (MFR) or melt volume rate (MVR) of a polymer.
The MFI tester consists of a heated barrel with a die at the bottom. A known weight of the polymer sample is placed in a heated cylinder, which is then pushed through the die under a specified load. The flow rate of the molten polymer is measured and recorded, usually in grams per 10 minutes.
Different types of MFI testers are available, including manual, semi-automatic, and fully automatic models. Some advanced models may also offer additional features, such as temperature control, data logging, and automatic calculation of MFI values.
