The aim of this work is to evaluate if rotational rheometry provides a more useful measurement of viscosity than capillary rheometry and melt flow index measurements in production environments. To achieve this, we compared the sensitivity of these methods for quality control in the batch production of a commercial fluorinated polymer by using statistical analysis and the ease-of-implementation criterion of each method. The utility of rotational rheometry to develop flow curves to assist blending in a batch process was also investigated.
