What Is Melt Flow Index Tester And Why Should You Use It

The MFI tester or melt flow index tester is one of the most useful testing instruments that will be used in the plastic as well as polymer industry. This amazing testing instrument will be helpful in measuring the resistance to the flow of materials like polymer that melts at a certain temperature. This test can be done under a given force at a pre-determined period of time. With the help of this testing instrument, you will easily be able to test the melt flow rate and viscosity under a certain load.

In this test, a specimen of a specific size will be placed in a heated barrel with a plunger or piston and the load is on the top inserted in the barrel to force the polymer to melt. Once the polymer gets melt or softens then weight should be placed on a piston and it will be forced through the die or orifice to come through.

If the rate of melt flow will be high and correlates with viscosity, then the resulted value of flow rate per unit will get increases if resin viscosity gets decreases. If the rate of melting an element is low then the viscosity will get high. Thus, you can effectively make use of an MFI Tester from Presto Testing Instruments. It has several features and benefits that will help you to test the specimen with ease.

You will find other laboratory testing instruments here at the best prices. Here in this blog, we will provide you with information about this amazing testing instrument and how it will be helpful in performing melt flow tests. So, let us get started with its importance and working.

How MFI Tester Will Help You With Testing?

With the help of a Melt Flow Index Tester, you will be able to gain several results. As we have already discussed above, the melt flow index tester will comprise piston assembly with a heated barrel that will be helpful in storing sample. You can calculate the melt index flow with the help of the melt index flow formula. This testing instrument will be helpful in checking the quality of materials used in finished products. Here are several things that you are likely to get with the MIF test.

  • It will be helpful in calculating the typical index value for verifying in-house material.
  • You can easily perform a quality check for index materials with the help of this test.
  • It acts as an evaluation tool that will be used by new material suppliers.
  • In a product development settling procedure, you can easily make use of laboratory testing instruments for checking the quality of the material.
  • You can easily do quick comparisons with new material suppliers.
  • You will get an estimation of flow properties with the help of this testing instrument.
  • You can easily predict the behaviour of polymer with a large number of processing techniques.

If you want to perform the MIF tests then we recommend you consult with us for guidance and support. You can either mail us or directly call us at our given number.

With the help of this testing machine, you will be able to predict the melt flow rate of plastics and polymers. Along with that, this amazing instrument will also let you calculate shear stress, shear rate, molecular structure, as well as the viscosity of the polymers.
