How to Get Precise Results from MFI Tester

Scrutinizing the quality of plastic polymers helios to ensure that the product that will be manufactured from these polymers will be of utmost quality. Be it analyzing the raw material or finished products, testing every element at every stage of production will help you examine how accurate the product is for the application.

There are many testing methods that are performed to test the quality of the polymers/plastic granules. One of the widely used testing devices is the Melt Flow Index Tester. You can easily measure the viscosity of the melted plastic using the Melt Flow Indexer. The testing machine helps you measure the flow properties of plastics at a certain temperature.

In the PET bottles manufacturing industries & polymer industries, measuring the Melt Flow Index Rate is one of the prominent metrics that needs to be determined before using the raw plastic granules for the manufacturing process. For this, producers must execute a MFI test so as to assure the quality of polymers is excellent and they will deliver high-quality products to the customers.

Continuing the discussion, in this blog we will provide you some worthy tips that will help you get precise test results from your Melt flow index tester while performing the quality test.

Assess the molten properties

Plastics is widely used for multiple purposes and hence commonly used in different production verticals in one or another way. Due to its wide usage, it became necessary for the manufacturers to test the quality of polymers in advance before using it for any manufacturing process. Testing the flow properties helps to measure the viscosity of the thermoplastics. Pacorr’s MFI tester gives you accurate measurements of the chemical and physical properties of the materials.

Using the Melt Flow Index Test Machine, you can simply assess the quality of plastic polyments. The machine comprises a microprocessor based temperature controller that controls the temperature from 0 to 400 degree celsius. The machine strictly adheres to various national and international industry regulations such as ASTM D 1238, IS 2267, IS-2530, IS 10810 that assures to give you extremely precise measurements of test results.

The rate of MFI of polymers is affected by multiple elements such as chemical interaction between molecules, molecular structure, viscosity and so on. When a polymer absorbs moisture, it acts as a plasticizer and increases the strength of plastics. This moisture can then influence the MFI of plastics.

Now, let’s consider the factors that must be cautiously considered while conducting the MFI of plastics and polymers. These factors will play a critical role and help you in obtaining accurate results from your Melt flow index test machine.

• Ensure that the machine you are buying is in good working conditions
• Check it is perfectly calibrated and all the controls and settings are working properly.
• Always make sure to clean and maintain your lab testing machine after every usage.
• Check whether the machine adheres to national or international test standards or not.
• Go through the manual properly to understand every part name in detail.

These are some of the common factors that surely must be followed to get accurate test results. You can give us a call or email us at info@pacorr.com. Our team of technical experts will help you assess you regarding all your queries.
