ρηεολογψ-It’s all Greek to me! Yes it is. But it doesn’t need to be. The term rheology comes from the Greek word rheos, which means “to flow.” Rheology is the study of flow. When you talk about squeezing, spreading, or lubricating a fluid, you are talking rheology. When you apply a force that causes a fluid to move, rupture, or flow, you are describing a rheological force.
Whether you are dealing with a fluid coating or a plastic product, you need to understand rheology. Rheology of the polymer in question affects not only the final product but the settings and limitations of the process.
But what is rheology? Stated simply, rheology is the “flow” of a polymer.
