Why is the Melt Flow Index Parameter important for Polymer Categorisation?

Plastic materials are widely used in many industries and have distinct levels of features per their use. Polymers used in making utensils might have different features and characteristics compared to those used in the aerospace industry. Now how the industry manufacturers decide what plastic material is required for which use - by the labelling that depends upon the properties of the plastic like flow properties. Now when you are going into the market selling off polymers to clients, you must ensure that the plastic is labelled correctly for their use and this differentiation will come with quality testing of the properties. Here comes the vital role of the Melt Flow Index Tester (MFI Tester).

How a MFI Instrument can help?
Melt Flow Index Test Machines are quality assurance testing instruments that are used to test the flow properties of the polymer. It is a tabletop machine that allows the user to insert polymer granule samples inside the tester and assess its melting and flowing behaviour. The machine has a barrel that helps heat the polymer granules to a limit so that they start melting and flowing out of the vessel. On the top of this barrel where the granules are put, one can put weight on the same to exert an external pressure to push it inside the barrel. When the polymer melts down and comes out it gets cut off after 10 mins of extraction. This extracted and cut sample is then weighed. The number that comes out is used in the calculation of MFI value that is:

MFI = Weight of test in grams/10 min

Now when you have the MFI value of the polymer you have, you can assess easily that it is suitable for which industry. Let’s suppose the value of the polymer used to make a toy car should be 6 and for utensils is 10 then you know what polymer you have to cater to which client.
