Melt Flow Index testing
Published: January 31st, 2013
Here is the scenario...I have a material cert from the manufacturer that shows a melt flow index of 11 g/10min with test conditions of 300°C/1.2Kg. We want to test the incoming material on our melt indexer but do not have a 1.2Kg weight. We only have a 4.2Kg weight. If I go ahead and run the test at 300°C/4.2Kg, is there some mathematical cartwheels I can do that would correlate the two indexes and tell me if they are close to equivalent?
