Pseudoplastic

Pseudoplastic fluids are materials whose viscosity decreases as the rate of stirring or movement increases. In simpler terms, they become thinner and flow more easily when stirred or shaken, but are thicker when at rest. A common example is ketchup: it resists pouring initially, but flows readily once you shake or squeeze the bottle. This behavior occurs because the internal structure of these fluids breaks down under stress, allowing easier movement. Pseudoplastic properties are important in various industries, including food, cosmetics, and paints, where controlling flow behavior is essential for processing and application.
