Melt flow rate tester (MFR test) The melt flow rate testeris used for fusion viscosity lower thermoplasticity plastic quality control, the testmethod is under prescribe temperature, load and piston in the cylinder and soon condition, use time test method measure fusion plastic through prescribelength and diameter hole speed, to evaluate the uniformity of the polymer flowrate. The MFR testing machineis defined as themass or volume of the thermoplastic melts at a given temperature and load, andthe melt passes through the standard die every 10 minutes. This instrument canonly be used for the determination of the melt flow rate (MFR) of the massmethod, which can be used to characterize the viscous flow characteristics ofthermoplastics in the molten state. Standards: ASTM-D1238: Standard test method forthermoplastic melt flow rate. ISO-1133: Determination of thermoplasticmelt mass flow rate (MFR) and melt volume flow rate (MVR). GB/T3682: Thermoplastics melt mass flowrate and melt volume flow rate measurement.
