MFI series Melt Flow Index Tester/Extrusion Plastometer.
They are suitable to measure the melt flow character of PP, PE, PVC, POM, ABS etc., plastic materials resin and granules.
Principle: The melt mass-flow rate (MFR) and the melt volume-flow rate (MVR) are determined by extruding molten material from the cylinder of a plastometer through a die of specified length and diameter under preset conditions of temperature and load.
Feature of MFI404:
Touching screen, both MFR/MVR test method, motorized cutting, with micro-printer, show the temperature VS Time graph.
Test Procedure:
Approximately 7 grams of the material is loaded into the barrel of the melt flow apparatus, which has been heated to a temperature specified for the material. A weight specified for the material is applied to a plunger and the molten material is forced through the die. A timed extrudate is collected and weighed. Melt flow rate values are calculated in g/10 min.
Specimen size:
At least 14 grams of material;
Data:
Flow rate = ( 600/t x weight of extrudate )
t = time of extrudate in seconds
melt flow rate = g/10 min.
Other name:
Melt flow index testing equipment; melting flow indexer; melt indexer iso 1133; digital melt flow rate tester; quality melt flow index testing machine; melt flow index astm; plastic Melting Flow Index tester
