ISO 1133 ASTM D1238 Melt Flow Index Tester
Description:
The melt mass-flow rate (MFR) and the melt volume-flow rate (MVR) are determined by extruding molten material from the barrel of a plastometer under preset conditions of temperature and load. For melt mass-flow rate, timed segments of the extrudate are weighed and the extrudate rate is calculated in g/10 min and recorded. For melt volume-flow rate, the distance that the piston moves in a specified time or the time required for the piston to move a specified distance is measured to generate data in cm3/10 min. Melt volume-flow rate may be converted to melt mass-flow rate, or vice-versa, if the density of the material is known under the conditions of the test.
