How MFI tester is helpful to test the molecular structure of plastics?

All matter is made up of molecules, small particles that are in constant motion. It is important to measure the resistance to the flow of materials like polymers that melts at a certain temperature. Thus, this can be done with the help of the Presto melt flow index tester. This is one of the amazing lab testing equipment that is used to evaluate the flow properties of plastics or resins with ease. This testing instrument has been provided with cylindrical cavity cleaning tools that will be a great help in cleaning the machines and attaining the most accurate test results. The Presto MFI tester is highly useful in testing the quality of plastic granules that are used to test the molding properties of plastic products with ease. Here in this article, we are going to provide you with the information about melt flow index tester designed by Presto and how it is helpful in testing the molecular structure of plastics with ease. So, let us get started!
