Nanofibrillated cellulose (NFC) and microfibrillated cellulose (MFC) can be obtained by the mechanical breakdown of natural fibers. These materials have the potential to be produced at low cost and may give many novel properties to paper, paper coatings, paints, or other products. However, suspensions of these materials have a complex rheology even at low solids. To be able to coat, pump, or mix NFC at moderate solids, it is critical to understand the rheology of these suspensions and how they flow in process equipment. Only a limited number of reports have been published in the literature on NFC rheology at moderate solids.
