Melt Flow Tester Market - Growth, Trends, and Forecast 2019 - 2027


Albany, NY -- (SBWIRE) -- 02/21/2019 -- Melt flow testers are mainly designed and developed to determine the MFR and MVR of molten polymer. The MFR stands for melt flow rate and the MVR stands for melt volume rate. Melt volume rate multiplied by the melt density of the material in the melted state gives melt flow rate. Melt flow rate (MFR) measures the viscosity of molten thermoplastic polymer based material in definite time interval and under certain temperature and load conditions (shear stress). Thus the melt flow rate is the well-known property of thermoplastic polymer which is measure using the melt flow tester.

The melt flow rate is given as the mass of thermoplastic polymer material, in grams, that is extruded in 10 minutes. Therefore, the melt flow rate is given as a mass per unit time and mass volume rate is expressed as volume per unit time. These tester provides the easy understanding of the behavior of the polymer for various processing techniques.

This testing process includes weighing the mass of a plastic that flows from the instrument over a certain timed interval i.e. 10 min and at a fixed temperature which is about 230°C. This process can repeated for more than 3 times and the average values are then considered as melt flow rate.

These testing are carried out with sustainable testing standards, such as ASTM D1238 and ISO 1133. Thermoplastic materials can be evaluated using the melt flow index method of analysis. The materials which are evaluated to determine the MFR and MVR are polypropylene, polyethylene, polystyrene, polycarbonate, and others.

In order to fulfill sustainable plastics processor's quality standards, the large number of plastic processors are using melt flow tester instruments to evaluate incoming material and test finished products. Thus the melt flow rate and melt volume rate values are important for the production process and the final inspection.

Furthermore, the melt volume rate provided by melt flow tester is a measure of the melt density of the material in g/cm³. Melt volume rate is an important property because its value is different than the solid-state density that is generally stated on the data sheets by the material supplier. Therefore, the melt flow tester are largely demanded by the material supplier and the product developer.

Also in several countries the acceptance of ISO 1133 and ASTM D1238 standards for polymer processing is highly increased due to the strict regulations associated with it.
