Plastics are considered to be the most widely used material in many industries. A lot of manufacturing units depends on quality plastics to ensure that their products are delivered securely. The melt flow index tester is mainly used to determine the rate of flow of a polymer when it gets exposed to heat and melted. The result you get while testing the index of melt flow is in the unit MFR. MFR is considered to be the melt mass flow rate. Another unit that will help you to measure the index of melt flow is MVR i.e. melt volume-flow rate.
In simple terms, it can be defined as the amount of mass as well as the volume of a polymer that will flow through a small aperture at a specified temperature as well as pressure. You can easily find this amazing instrument on the Testing Instruments website. Here you will also find other lab testing instruments that will be helpful in checking the quality of materials.
Here in this blog, we are going to define the importance and role of melt flow index tester and how it can be useful in determining the sustainability of plastics.
Role of MFI Test in Determining the Sustainability of Plastics
The MFI test is massively related to testing the quality of plastics. It will be universally used in the plastic products processing industry. You can easily calculate the melt flow rate of plastics with the help of lab testing instruments. With the help of an MFI tester, you will be able to determine the density of the material used. This is more beneficial in terms of plastic recycling. You will also find other properties like tensile and impact performance.
The melt flow machine carries out the test under certain prescribed conditions of temperature, load as well as piston position. This machine plays an important role in testing the properties of plastics which in turn determines the quality used.
The MFI tester indicates the quality control of various products made of plastics and polymers. On the basis of melt flow rate, you can use major criteria for material acceptance in industries for the manufacturing process. The melt flow rate of a particular specimen that is used for testing is always inversely proportional to the molecular weight of the material. Those plastic materials that have high index value will be easy to process. Thus, the plastics used in the industries must have the right weight that can be used in the manufacturing industry. The help of the test conducted by the MFI tester by Testing Instruments will also help the manufacturers to make the necessary changes in the manufacturing process. This will help them in maintaining the best quality of the material.
There are many other uses of MFI tester as well. We have created a list of those uses below.
Use of MFI Tester
The MFI tester is also used for various other purposes. This amazing lab testing equipment will not only help to determine the properties of plastics but will also help in evaluating their quality. Here we have listed some of the amazing uses of this testing instrument.
- The MFI tester serves to be the most useful tool to estimate the flow properties for a simple extrusion process.
- This amazing evaluation tool is useful for new materials suppliers.
- You can easily do a comparison of new materials in the product development cycle.
- With the help of this test, you can easily ensure that the material is made of pre-defined standards or not.
These are some of the uses of MFI tester. You can take help from Testing Instruments to get complete guidance on the use of this lab testing instrument.
