Mfi to viscosity conversion
Webb24 juni 2013 · Flow rate in a polymer is related inversely to viscosity. High-viscosity materials flow with greater resistance and therefore more slowly under any particular set of conditions than low-viscosity materials do. Therefore, higher-MW polymers have lower MFR values and lower-MW polymers have higher MFR. WebbThe amount of polymer that flows out of a capillary of fixed dimensions is given in grams per 10 minutes. A high MFI corresponds with a low viscosity (easy flow) and vice versa. Other rheological properties such as elasticity, tan delta and viscosity can be determined via more complex devices like the RDS.
