Testing the quality of plastics and polymers will help you to ensure that you are using the right products. Thus, from raw material to compounds and finished products, testing each and every element will help you to determine how accurate the material is. There are certain tests that needed to be taken while ensuring plastic quality. One of the important factors that determine plastic quality is the melt flow rate. This parameter will be determined using the Testronix melt flow index testerThis lab testing equipment will help you to analyze the flow properties of plastics at a certain temperature.

In the PET and polymer industries, the melt flow rate is an essential metric that needs to be determined before delivering products to the customers. Prior to manufacturing, producers must execute a melt flow index test so as to assure the quality of products delivered to the customers.

Here in this blog, we will provide you with some useful tips that will help you to get accurate test results while performing the quality test using this melt flow index tester for thermoplastics.

Quickly assess the molten properties of materials with an MFI tester

Plastic has become a go-to material in circumstances where innovation has increased the use of polymer raw materials, resins, and composites. Because plastics are so common, it's more necessary than ever for manufacturers to maintain strict quality control. Testing the flow properties of polymers & thermoplastics is one of the essential quality control tests that needed to be conducted in order to assess the molten properties of these materials. Testronix has come up with one of the highest quality MFR testers that give you accurate testing results of the physical and chemical properties of the materials.

With the use of MFI Tester, you can simply assess the product's quality. A microprocessor-based PID temperature controller ranging from 0 to 400 degrees Celsius has been embedded in the Testronix melt flow index tester. With a resolution of 0.1 degrees Celsius, it gives you an extremely precise measurement of test results. This testing equipment complies with all industry regulations (ASTM D 1238, IS 2267, IS-2530, IS 10810).

The melt flow index of a material is influenced by a variety of elements such as molecular structure, chemical interaction between molecules, and so on. When moisture is absorbed, it acts as a plasticizer, lowering the glass transition temperature and increasing the strength of plastics. The moisture can influence the melt flow index of plastics and make sure that leads to irreversible degradation of polymer structure.

Now, let us focus on the factors that you need to be taken care of while conducting the melt flow index of polymers and plastics.

Factors that play a critical role in obtaining accurate results from the MFI tester

Melt Flow Index (MFI) or Melt Flow Rate (MFR) is considered to be an important materials property test used in the plastics industry. This quality test determines the melt flow characteristics of resins at certain shear stress (relative to the applied load) and temperature.

Testronix melt flow index tester is one of the standardized testing equipment that plays a significant role in testing the melt flow properties of plastics.

Below we have listed some of the essential factors that must be determined in order to get accurate results while testing your product.

  • Whenever you buy this lab testing instrument from manufacturers then, you must ensure that it is working in a good condition.
  • The melt flow index must be calibrated by certified manufacturers and all the parameters must be properly checked including the temperature, physical dimensions, distance, and time measurement accuracy.
  • Also, you must ensure that the lab testing equipment you purchase should properly be cleaned and must be maintained. You can easily read about the tips to maintain the melt flow index tester.
  • Periodic testing of standard reference material (SRM) or control materials must adhere to strict testing protocols and regulations.

These are some of the factors that must be determined in order to get accurate test results. You can give us a call at +91 9313140140 or email us at Our team of technical experts will easily assess you regarding all your queries.
