-The melt flow index test machine(MVR) is a laboratory instrument used to measure the flow properties of a polymer melt. This test is important for determining the viscosity and flow behavior of a polymer material, which can affect its processing and performance in various applications.
-The melt flow index test is commonly used in the plastics industry to compare the flow properties of different polymer materials and to ensure consistency in manufacturing processes. It can also be used to predict the processing behavior of a polymer material and to troubleshoot any issues that may arise during production.

-This kind of instrument can be used to test the melt flow rate(MFR) figures of all kinds of plastic and resin in the viscous flow state. It is not only suitable for the high melting temperature engineering plastics of polycarbonate, polyarylsulfone , fluorine plastic and nylon but also suitable for some other low temperature plastic products which are made up of polyethylene(PE), polystyrene(PS), polypropylene(PP), ABS resin, polyoxymethylene(POM) and polycarbonate. So it is not only widely used in the plastic production, petroleum and chemical industry but also in the relevant institutions such as scientific research units and the community inspection departments.
