How to Choose the Right Melt Flow Index Tester for Your Manufacturing Needs
In the competitive world of manufacturing, ensuring product quality is vital, especially when dealing with polymers and plastics. One of the most important tools for maintaining consistent quality is the melt flow index tester , which measures the flow properties of polymer materials. By providing essential data, this instrument helps ensure materials meet strict performance standards, making it a critical component in the manufacturing process. What is a Melt Flow Index Tester? A melt flow index tester —also known as an MFI tester or melt index tester—determines how a thermoplastic polymer melts and flows under specific conditions. The result, known as the melt flow index (MFI) or melt flow rate (MFR), is calculated using the melt flow index formula . During testing, polymer pellets are placed in a heated barrel, where they melt. A pre-determined weight is then applied to push the material through a die, and the amount of polymer extruded over a set period (usually 10 minutes) ...
