Melt Flow Index Tester is one of the major testing protocols followed in the polymer industry. The MFI test is considered to be a mandatory criterion to clear for products before they can be selected ahead of production. The MFI value determines the molecular weight of the polymer and helps the manufacturer to assess the melting behaviour of plastic material.

The MFI test is a procedure in which a polymer sample is placed inside the tester, heated at a standard set temperature. The molten plastic is then pushed through a standardized die with a specified diameter by exerting a fixed amount of weight. The molten plastic which comes out within 10 min of time is evaluated. This value is the Melt Flow Index. Lower The MFI value, Higher is its Flexible nature. The same procedure when performed on multiple samples helps the manufactures to categorise as per the quality and can easily decide its further use.

The melt flow index tester comes with automated services like automated sample cutting which ensures that when the fixed time of 10 min completes the melted sample is automatically cut off and the test procedure stops. Once the procedure ends the user no need to weigh the material separately as the equipment deliver an automated weighing service too with an in-built digital weighing balance. The High-end MFI tester also brings an auto MFR Calculator. Hence, the user is free from manual cutting, weighing and evaluating the test results.

The equipment has an inbuilt window based software and RS 232 port that can connect your equipment to your computer. With a simple installation of the software, the user can get the test analysis reports on their system. With the help of computer connectivity, it becomes very easy to analyze and generate test reports. It is also equipped with precision-based features like Microprocessor-based temperature control that ensure higher accuracy of temperature maintained during the test.
