Inspect Molten Nature of Plastic Granules with MFI Tester

The polymer-based raw material that is used for commercial use in manufacturing industries is selected on numerous basis. They are inspected over their structural, physical and chemical properties. One of these factors is the molten nature of the polymer. The way a polymer melts down in a fixed time window can tell a lot about its production quality. Hence, such properties must be tested way before we decide on the production process. Therefore, we bring a testing solution that is high-end and advanced and also, fully automated in nature, the Automatic Melt Flow Index Tester-Computerized. In this blog, we will read more about, the role of MFI & MFR value and how the latest machine can help.

Importance of evaluating the MFI & MFR value in the polymer industry

Plastic is made up of polymer networks of molecules bound together strongly with each other. To mould the plastic one must break down this chain of linking and give the plastic a new shape. This process is known as the melt-down of polymer. But before that, it is beneficial to know the nature and behaviour of plastic when they are at a melting temperature. This is done using granules of polymer material to be tested. Granules formation are easier to handle and insert in a melting chamber of any size. When a fixed amount of polymer is heated at a specific temperature and under a defined load, the weight of the molten polymer that is extracted within 10 minutes, is called the Melt Flow Index or MFI of that polymer. Similarly, we can apply the formula and calculate the MFR or Melt Flow Rate of Plastic. These values are highly important in the inspection of plastic quality. The MFI values also help in categorizing plastic for its intended use in many industries.

Melt Flow Index Tester is a high-end and latest generation quality testing machine. It is a fully automated and user-friendly equipment that allows the user to test the MFI and MFR values of plastic granules. The equipment is a highly efficient plastic & polymer testing instrument that brings advanced features like HMI-based operation management. Easy setting of test parameters and automated extracted molten polymer flow cutter. It comes with a range of loads that can be applied to the testing sample so that the user gets maximum opportunity to conduct a wide spectrum of testing.
