• Product Model：CMC-500
• Viscosity (1% solution, mPa·s)：400–700
• Main Applications：Paper coating, moderate viscosity drilling mud
• CAS number：9004 32 4
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.
