What Factors Affect Melt Flow Index Testing? Several factors can influence the results of Melt Flow Index (MFI) testing, impacting the accuracy and reliability of the test. Key factors include: 1. Temperature: The test temperature must be precisely maintained as per the material standard, as small fluctuations can alter polymer flow behavior. 2. Load/Weight: The applied load directly affects the polymer's flow rate; deviations from the specified weight lead to incorrect readings. 3. Material Composition: Variations in polymer types, additives, or fillers can influence viscosity and flow rate. 4. Pre-test Conditioning: Moisture content and thermal history of the sample can affect results. 5. Barrel and Die Condition: Clean, well-maintained equipment ensures consistent flow. 6. Operator Technique: Consistent test procedures prevent human error. Email :- info@prestogroup.com Call Now: +919210903903 https://www.testing-instruments.com/melt-flow-index-tester/
