Viscosity & Flow Behavior
The rheological properties of Carboxymethyl Cellulose are among its most important functional characteristics. CMC exhibits pseudoplastic (shear-thinning) behavior, where viscosity decreases under shear stress. Understanding these properties is crucial for optimizing CMC performance in applications such as drilling fluids, coatings, and food products.
CMC solution viscosity is significantly affected by temperature changes, showing typical polymer behavior.
The viscosity of CMC solutions is stable within a specific pH range, with significant changes at extremes.
CMC shows excellent compatibility with glycerol, commonly used in cosmetic and pharmaceutical applications.
