Why Melt Flow Testing Optimizes Your Productivity


MFi Series Why Melt Flow Testing Optimizes your Productivity Diagram



Melt flow testing is simply a measure of the flow of a polymer when melted. The result of a melt flow test, called the melt mass-flow rate (MFR) or melt volume-flow rate (MVR), is defined as the amount of mass or volume of a polymer that flows through a small die at a specified temperature and pressure.
