What are the characteristics of the polymer melt flow?
Intumescent fluids, typically high solids polymer fluids, are such that the shear is increased and the viscosity increases.
Pseudoplastic fluid, the vast majority of polymer fluid is this type, the temperature increases, the shear increases, the viscosity decreases
Bingham fluid, shear over the threshold before the flow, after the flow of pseudoplastic fluid characteristics.
Newtonian fluid, and shear is proportional to, generally only very low degree of polymerization of the polymer is such a fluid.
