"Shape Memory Alloys are reported to show an interesting phenomenon known as Superplasticity or Pseudoplasticity [26].
On the other hand, mango pulp remarkably influences the pseudoplasticity of these mixtures.
After adding CaC[O.sub.3] nanoparticles, they act as a lubricant and reduce the entanglements between molecular chains, so the pseudoplasticity reduces and the n increases with increasing CaC[O.sub.3] content.
The additional information gained is an understanding of the "degree of pseudoplasticity" that exists in the fluid.
BASF Corporation has been awarded a patent for an effect pigment PVC plastisol comprised of at least one finely divided PVC homopolymer, prepared by emulsion polymerization or microemulsion polymerization, having particle sizes of from 0.04-40 [micro]m, and which as a dispersion in a plasticizer exhibits dilatancy; at least one finely divided PVC homopolymer, prepared by emulsion polymerization, having particle sizes of from 1-400 [micro]m, and which as a dispersion in a plasticizer exhibits pseudoplasticity; at least one plasticizer; at least one effect pigment and at least one additive, wherein the additive is comprised of an organic solvent, and the weight ratio is chosen so that the PVC plastisol exhibits pseudoplasticity.
The zero shear-rate viscosity and pseudoplasticity index decrease could be correlated with the plasticizer content by using an exponential function.
Another term for shear thinning is pseudoplasticity (ref.
These benefits come in addition to other typical properties of xanthan gum, such as stability, when exposed to the high salt levels and range of temperatures likely to be encountered at the seaside, compatibility with a wide range of ingredients, excellent suspension stability and pseudoplasticity characteristics.
This effective increase in polymer molecular weight, as a result, will cause the viscosity and pseudoplasticity of the ink to increase.
Results indicate that, in addition to viscosity, the pseudoplasticity and elasticity of emulsions play a significant role in stabilizing citrus drink emulsions.
The correct pseudoplasticity of the thick-film paste will prevent seepage from occurring.
