Melt Flow Index
Flow behavior checked using the method and conditions agreed for the product.
Possible checks cover material identity, consistency, process behavior, and sample approval as applicable.
The relevant control plan is determined by material type, process, application, and customer agreement.
The checks below are possible evaluation areas, not a claim that every test is performed on every product or by an accredited laboratory. The confirmed inspection scope belongs in the product agreement.
Final values, tolerances, sampling frequency, test methods, reporting, and approval responsibilities depend on the selected product and written customer agreement.
