The melt flow index (MFI) is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes through a capillary of a specific diameter and length by a pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures.[1][2] Polymer processors usually correlate the value of MFI with the polymer grade that they have to choose for different processes, and most often this value is. The melt (flow) index has become a widely recognised criterion in the appraisal of extrudability of thermoplastic materials, especially polyolefins. It is standardised as the weight of polymer (polyolefin) extruded in 10 min at a constant temperature (190 °C) through a tubular die of specified diameter (0.0825 in. = 2.2 mm) when a standard weight (2.160 kg) is placed on the driving piston (ASTM D 1238) Melt Flow Index Test is a very simple method that helps to characterize the flow properties of the melted plastics. This test method is widely used for the quality assurance purposes and raw material resting. This test can be performed using high-quality of Melt Flow Index Testers

Melt flow tests are a simple method of characterizing the flow properties of a plastic melted mass. This test method is widely used, especially in quality assurance and incoming goods inspections. Demands on the extrusion plastometer vary according to which processing stage in the plastics industry is involved The Melt Flow Index (MFI) is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes through a capillary of a specific diameter and length by a pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures The melt flow index is commonly used by suppliers of polymer stock and those in the injection molding or extrusion industries to determine processing conditions for different grades of polymer Der Schmelzindex (engl.: MFR = Melt Mass-Flow Rate früher MFI = Melt Flow Index) dient zur Charakterisierung des Fließverhaltens eines thermoplastischen Kunststoffes. Zur Messung des Schmelzindex werden Schmelzindexmessgeräte (Bild 1) verwendet, die eine besondere Ausführungsform eines Kapillarrheometers darstellen [1]

Melt strength is even less closely related to traditional shear viscosity measurements, so that melt flow/melt index measurements are not a significant indicator of melt strength. A variety of methods have been developed to measure melt strength as it applies to practical extrusion. The main one has been the Goettfert Rheotens device where a molten extrudate or fiber strand is pulled between two powered rollers as it leaves a downward-extruding orifice. As the speed of the rollers is. The basic version of the Mflow extrusion plastometers can be used to determine melt mass flow rates (MFR). It features a modular design, and use of the piston displacement transducer expands the Mflow's capabilities to include determination of melt volume flow rate (MVR), as well as automatic, field-dependent parameterization. These extrusion plastometers are typically used for quality assurance and incoming goods inspections Table 2: Polyolefin Film Extrusion Resins * Melt Index describes the flow behavior of a resin at a specified test temperature (190°C, 374°F) and under a specified weight (2,160g). Resins with a higher melt index flow more easily in the hot, molten state than those with a lower melt index

Melt Flow Index is an assessment of average molecular mass and is an inverse measure of the melt viscosity; in other words, the higher a MFI, the more polymer flows under test conditions. Knowing the MFI of a polymer is vital to anticipating and controlling its processing. Generally, higher MFI polymers are used in injectio Melt flow index is a measure of how 'runny' the plastic is - how it flows through an extruder. Different plastics for different applications need different MFI's to make them easy to mould. You can see on this page more information about how Melt flow index (or melt flow rate) is performed and calculated

Melt flow index is defined as the rate of extrusion of molten resin under specified temperature and pressure through a specified size of die in 10 minutes. It is expressed in g/10 min.

Scope: Melt Flow Rate measures the rate of extrusion of thermoplastics through an orifice at a prescribed temperature and load. It provides a means of measuring flow of a melted material which can be used to differentiate grades as with polyethylene, or determine the extent of degradation of the plastic as a result of molding. Degraded materials would generally flow more as a result of reduced molecular weight, and could exhibit reduced.

During the processing of thermoplastic by injection molding or extrusion one of the most important characteristics of the material is the melt flow index of polymer. The possibility of its processing one way or another depends on this value.

INTRODUCTION TO MELT FLOW MEASUREMENT MELT MASS-FLOW RATE AND MELT VOLUME-FLOW RATE The measured flow of a thermoplastic material through a die following specified conditions of length, diameter, temperature and pressure is known as either its Melt Mass-Flow Rate (MFR) or Melt Volume-Flow Rate (MVR). Differing standard conditions of extrusion temperatures and pressures are use Melt Flow Rate (MFR) is the mass of a polymer that flows through a capillary at a specified temperature and pressure during a measured time period. The MFR is the mass of polymer that flows during the test, normalized to 10 minutes. The calculated MFR value is related to molecular weight: the higher the MFR, the lower the molecular weight. MFR is also inversely proportional to viscosity: a melted material's ability to flow when under pressure. Lastly, we can compare MFR values of a single. higher Melt Flow Index.If it does not adversely affect the mechanical properties of the final product, switch-ing to a higher MFI material allows higher throughput rates before melt fracture occurs.1 • Decrease the elasticity of the resin.This results in a higher critical shear stress value for the polymer.2 • Incorporate low molecular weight additives into the base resin.A small amount (5.
