What is a Melt Flow Index?
Melt Flow Rate (MFR) or Melt Flow Index (MFI) is the flow measurement of polyethylene being pushed through a 2mm diameter die at 190°C with 2.16 kg mass. The result is expressed in grams per 10 minutes (g/10 min).
Experimental Procedure Summary
Approximately 6 to10 grams of polyethylene is loaded into the barrel of the melt flow plastometer, heated to a temperature of 190°C. A plunger is placed into the barrel on top of the polyethylene pellets for a specified amount of time with a pre weight. A 2060 gram weight is applied to the plunger to force the molten polyethylene through the 2mm die. Several timed extrudates are collected and weighed. Melt flow rate values are calculated in g/10 min.
Calculation of Melt Flow Rate = (600/t(sec) x mass of extrudate in grams)
t = time of extrudate in seconds
