Extrusion Plastometers, in laboratory plastic melted mass Flow Index Testers ISO 1133, ASTM D1238, The melt mass-flow rate (MFR) and the melt volume-flow rate (MVR);

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.

Extrusion plastometers, also known as melt flow index testers are used to determine the melt mass flow rate (MFR) and melt volume flow rate (MVR) of a plastic melted mass. Measurement of the flow behavior of the melted material is used to compare different grades of the same polymer and provides an important parameter for quality assurance and incoming goods inspections, for material selection and the setup of processing machines by plastics processors. Demands on these melt flow indexers vary according to which plastics processing stage is involved.

Feature of MFI402:
LCD display, only MFR method, motorized cutting, with micro-printer.

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
