Detailed parameters

The solution properties I


CMC hydration time counts from initial wetting to becoming viscous. It can be adjusted by degree of substitution and pH value, typically ranging from a few to over 30 minutes.


The solution properties II


In industrial applications, shear rate affects CMC dosage for target viscosity. CMC shows shear-thinning behavior: viscosity decreases as shear rate increases.


The solution properties III


CMC solutions are pseudoplastic, with rheology depending on concentration and molecular weight. They offer good salt tolerance and film-forming properties.
