Plastics are used widely to produce various domestic and industrial products. The manufacturers in the plastic industry test the quality of the plastics before commencing the production process. The very first choice of the manufacturers while setting their industrial laboratory to test the quality of the plastics is Melt Flow Index Tester. The testing instrument is used to determine the Melt Flow rate and Melt Flow volume of the plastic resins or granules. The melt flow rate is calculated to ascertain the viscosity of the plastic.

To maintain and to enhance the quality of the products, manufacturers in the plastic industry use melt flow index tester to test the quality of the plastic granules. The instrument is considered as the best testing device that helps to measure the viscosity of the plastics.
The melt flow test is the best test which is considered by all the standardization authorities to measure the quality of the plastics. The test is first introduced in the 1950s, and the simplicity of the test has remained the same since then. The Melt Flow Test offers highly accurate, repeatable and reliable test results.
Working of Melt Flow Index Tester
The testing equipment is equipped with a heated barrel, a piston in which the samples of plastic resins are poured. A specific amount of weight is applied to the granules which come out in the form of melted plastic from the capillary tube. The melted specimen came out of the capillary tube in a given period of 10 minutes is then measured in terms of grams. It is very easy to test the MFR of plastics with the help of Melt Flow Index Tester. This is known as the melt flow index of plastics.
Properties That Can Be Measured With Melt Flow Index Test
The basic property which is measured with the help of melt flow index tester is the viscosity of the plastics or flow rate of plastic at a particular load and temperature. The polymer with short molecular structure shows less flow and the complex structure shows the high molecular weight of the plastics. This helps to judge the exact molecular weight of the plastics.
Melt Flow Index Test is the best testing procedure that contributes to evaluating the quality of the resins that are provided by the different vendors. The test is mainly used to ensure whether the quality of the plastic is good or not. The effect of the change which is measured in the Melt Flow Rate of the Plastics indicates the rate of degradation in the quality of the plastics.
