Plastometer MFI404 / CE / MFR & 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. 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.
