WebMFR is a simple test and is useful in that a feel for polymer viscosity can be attained very quickly. Furthermore, the MFI value is indicative of polymer weight average molcular weight and, if using the ratio of two MFR values from dissimilar weights (flow rate ratio-FRR), its molecular weight distribution. WebMFR (and MVR) are obtained under standard conditions of temperature and applied load, defined for each type of material, and normally using a fixed type of die (inner diameter …
