The Melt Flow Index (MFI) is a proportion of the simplicity of flow of the melt of a thermoplastic polymer. It is characterized as the mass of polymer, in grams, flowing shortly through a fine of a particular distance across and length by a pressing factor applied by means of endorsed elective gravimetric loads for elective recommended temperatures. Polymer processors typically relate the estimation of MFI with the polymer grade that they need to decide for various cycles, and frequently this worth isn’t joined by the units, since it is underestimated to be g/10min. Also, the test states of MFI estimation is typically communicated in kilograms as opposed to some other units. The technique is portrayed in the comparative principles ASTM D1238 and ISO 1133. Measurement of Melt flow index is an important test method known in Polymer Industry. It categorise to choose the plastic material with a specified MFI value for a specific application. However, it is difficult for the manufacturers to test various forms of plastics by using one equipment.
Melt Flow Index Tester by Pacorr is efficient testing equipment that is designed and developed for evaluating the Melt flow index of various plastics in their granular form. Pacorr offers the instrument at one best and industry competitive price. One of the most renowned machine among leading polymer manufacturing brands to test the molten flow properties of plastic granules. It adheres to ASTM D 1238-1992, IS 2267-1972, IS 2530-1963, and IS 10810-1984 international test standards.
Equipped with sophisticated digital controls based on chip based program to give the most accurate results in the test. It has automated molten sample cutting that reduces errors and makes it totally unmanned. Melt Flow Index Tester International Equipments has digital based Display screen with bright LED lights fitted to it. It displays the test data that is clear and is accurate in recording fluctuations. It consist of a die steel cylindrical barrel to give uniform and constant heat at the time of the test.
To start the test for measuring Melt flow index of various plastics, put plastic granules inside the cylindrical barrel of Melt Flow Index Tester for heating. The barrel is designed to deliver uniform heating of granules. This avoids a situation where some granules are melted and some are not. It can give incorrect data. Range of different weights are available with the machine. These loads are applied on top to apply a specific amount of pressure. The granules when melted, flow out of the machine and the auto-cutter cuts down a specific amount of polymer flow. The plastic when cooled down is weighed and the MFI index is measured. It can be used to calculate MFR and MVR.
