The Melt Flow Index is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer in grams flowing in 10 minutes through a capillary of specific diameter and length by pressure applied via prescribed alternative gravimetric weights...

The gradient column method accurately measures the density of small solid materials. The density is formed by mixing two fluids having different densities. The resulting solution has a density which when introduced into the column increases uniformly from top to bottom.Ray-Ran's...
