The term "pasty" evasively qualifies the state of materials and products with more or less "soft" textures and behaviors that are generally difficult to flow.
In terms of physical behaviors, “pasties” generally exhibit non-Newtonian properties (see our article Viscosity, Rheology and Confusion), a mechanical strength of the semi-solid type and properties at the interfaces, of the sticky or sliding type, more or less marked.
The mushy state, sensitive diet
Countless materials and formulations, in all industrial sectors, pass through a pasty state depending on concentration, thermal or mechanical conditions. Controlling the contributions of these different factors is crucial both in the formulation and in the sizing of the processes.
Depending on the specifics of the process or the application, certain behaviors and parameters control the “processability” or the “applicability”; these are the ones that need to be quantified in order to become predictive.
