What is MFI Tester for Plastics and How Much is its Price in India?

In today’s times thermoplastic polymers or plastics are extensively used in various industries, not only for industrial applications but also for domestic purposes. Considering the popularity of plastics, it is important that plastic products should comply with international standards of quality assessment.

Melt Flow Index or MFI is a measure of the ease of flow of a thermoplastic polymer, when it is melted.

What is Melt Flow Index?

MFI or Melt Flow Index is defined as the weight of a polymer in grams flowing through a die of specific diameter and length, in a time period of 10 minutes, when a specified pressure is applied, by a given weight at a given temperature. This is standard method followed in the industry, as per ASTM D1238 and ISO 1133. 

How is MFI or Melt Flow Index Tested?

Thus, MFI or Melt Flow Index is one of the most important properties of a plastic, since it helps in studying the behavior and molecular structure of the thermoplastic material. In order to ensure excellent quality, strength and safety of the plastic product, manufactures conducted Melt Flow Index testing, using standard equipment called the Melt Flow Index Tester.

The standard method for testing the Melt Flow Index or MFI of a thermoplastic material involves, performing the MFI test on plastic granules. The results obtained are analyzed by the quality control department, to decide whether or not the sample under test is suitable for use, based on its physical as well as synthetic properties. These properties are accurately analyzed by conducting the MFI Test.

Benefits of Melt Flow Index Tester

Here are Seven Benefits of performing the Melt Flow Index Test – It can be used for:

• Comparing materials for product development
• Evaluating samples from new material suppliers
• Estimating flow properties for simple extrusion processes
• Predicting a polymer’s behavior for certain processing techniques
• Quick comparisons for quality and production control
• Conformance of a material to a Certificate of Analysis
• Grade differentiation of materials

Purpose of Melt Flow Index Tester

MFI is a characteristic which is primarily useful for measuring uniformity of flow rate of materials. Thus, the purpose of using a melt flow index tester is to determine the melt flow index rate. This can be further used for grading of Thermoplastic material and determining their quality.

It can also be used for determining lot-to-lot consistency of resin or thermoplastic materials. As per the principle we know that any material which has a high molecular weight has more resistance to flow, as compared to a material or polymer with less flow resistance and molecular weight.
