Melt Flow Indexer (MFR/MVR) vs. Capillary Rheometer A Capillary Rheometer as well as a Melt Flow Indexer (Plastometer) can compare the flow behaviour of polymer plastics..

Melt Flow Index or Melt Volume Rate is the measure of the ease of the flow of the melt flow of the thermoplastic polymers The melt flow index is the unit which is used to determine the rate of flow of a polymeric material in its molten state. The MFI can be defined as the mass of the polymer in its molten state that can flow through a capillary tube with specific dimensions under the effect of a shearing pressure that is applied on the material with the help of weights and gravity. The MFI plays a significant role in deciding the physical properties as well as the structure of the polymer. The greater the melt. Originally called Melt Flow Index or Melt Index (typically for polyethylene, but applied to a variety of materials), the standard designation today is Melt Mass-Flow Rate or MFR, which is a mass flow expressed (SI units) in g/10min. An alternative quantity is the volume flow expressed (SI units) in cm3/10min, called Melt Volume-Flow Rate or MVR The Melt Flow Index Test measures the rate of extrusion of a Thermoplastic material through orifice of Specific Length and Diameter under prescribed conditions of temperature and pressure. The Saumya MFI Tester are built to measure Melt Flow Rate with greater accuracy as prescribed in different national and international standards Melt flow rate testing can be characterized as the Rodney Dangerfield of material test methods—it gets no respect. People from all parts of the industry downplay the value of the test or denigrate its usefulness outright. Those who instruct industry professionals on processing are quick to point out that the melt flow rate (MFR) value for a material is a single point on a curve that.

The Plastic melt flow index tester is calculated by performing a manual/ automatic test procedure on a testing instrument in order to check the melt volume rate of the flow of plastic granules (which is measured in grams in a precise time of ten minutes). The procedure passed through a die having a particular measurement in diameter and length The melt flow rate is measured by putting the plastic resin under test in a testing equipment called a melt low indexer, heating the plastic resin, making the molten plastic resin with a prescribed weight to flow, and measuring the weight of the plastic that flows out as an index of the melt flow rate. The method of this test has been stipulated in JIS and ISO standards 1.0 INTRODUCTION TO MELT FLOW INDEXING 1.1 MELT FLOW RATE The melt flow rate (MFR) of a thermoplastic material is the measured gravimetric flow of the sample extruded through a die following specified conditions of die length, diameter, tem-perature and pressure.

The melt flow rate from method A is equated to the method B flow rate equation and solved for apparent melt density. This test is valuable because it means that a valid apparent melt density can be obtained. This can be used later in a solo method B test (in method B there are no manual cuts of extrudate or weighing) in order to achieve results that are equivalent to method A (in method A the.

Mass flow index tester operation, also called an extrusion plastometer or sometimes MFI, tests for the melt flow rate (MFR) which is calculated from the average mass extruded and cut at an interval and then factored for the calculated rate in 10 minutes In order to fully appreciate the strengths and weaknesses of the melt-flow-rate (MFR) test it is important to know something about the way the test is performed. The methodology is covered by ASTM D 1238, while the corresponding international standard is ISO 1133. There are small differences between the methods, but they essentially perform the same function. (Link to Part 1 top right of this. They introduce this molten sample into our melt flow indexer, which uses a piston system to squeeze it through a minuscule aperture in a metal die for a specified period. By calculating the change in the sample's weight after this process, our team can determine the flowability of the polymer sample. In addition to determining how a material will behave during processing, melt flow index. Melt Flow Rate (MFR) or Melt Flow Index (MFI) is the flow measurement of polyethylene being pushed through a 2mm diameter die at 190°C with 2.16 kg mass.

Due to the flow behaviour, the degree of polymerization can be derived, which on the other hand has an influence on the later mechanical properties of the molded plastic. Since plastics are sometimes sensitive to moisture, the increased moisture in the granules during the melting process during injection molding can lead to the shortened molecular chains and thus to poorer mechanical.
