MFR Value Inspection of Thermoplastic Granules

Thermoplastics are the most widely used polymer material used in many industries. They are preferred for their flexible nature and quicker melting point. In their use in multiple manufacturing companies and products, they must fulfil distinct quality requirements as per their industry needs. Hence they must undergo structural and chemical inspection rounds. In this blog, we will read how Melt Flow Index Tester can be useful in performing quality evaluation and ensuring the best production.

Why do we need to test the Melt Flow Rate of Thermoplastic?

Thermoplastics are low melting point based materials that are used in a variety of industries and can shapeshift easily. The melting nature of the polymer tells a lot of things about its chemical and physical nature and also must be considered for incurring quality in the production line. The Melt Flow Rate of thermoplastic can help the production engineer understand the need for production facilities to be aligned. The MFR value is the rate at which the polymer is molten and extracted under a specified load within a time of ten minutes. The extracted section of this molten plastic is weighed and the Melt Flow Index or MFI is extracted from the same we can further know the MFR value too.

Melt Flow Index Tester is a highly efficient Plastic & Polymer Testing Instrument. The machine is made as per international testing standards so that it can deliver test results that are acknowledged worldwide. The machine comes with a wide range of loads so that one can conduct distinct types of test procedures. It allows easy insertion of granules and delivers an appropriate environment to melt the polymer granules inside a barrel. The barrel body is composed of high-quality and repute-make parts that give a long-life performance. All the test parameters like what temperature is procured and how much load is applied to the process and how the time is shown on a microprocessor-based digital display screen. The machine allows easy extraction of the molten material which can be cut after 10 mins of extraction and weighed to know the MFI or MFR value of the material.
These values not only will help the user to know how the polymer will further behave during the production but also helps them in categorizing the same thermoplastic material as per their distinct MFI values. This can help them to place these materials for different end-use as per their chemical nature.
