CMC

Carboxymethyl cellulose  (Paper-making Grade)
Synonyms: Cellulose carboxymethyl ether sodium salt; CMC sodium salt
CAS: 9004-32-4

Application:
Paper-making grade CMC is used as paper sizing agent and can evidently increase paper's dry intensity, wet strength, oil resistance, ink absorbance and water resistance. It can make the paper has good ink permeability and can improve the adhesion between the paper fibers. That will improve folding resistance of paper and reduce the printing dust. improving print quality and reduce porosity.

CMC's application in paper-making industry

1. Pigment coating
·Control and regulate the rheology of coatings and dispersibility of pigments.
·Get pseudoplasticity of coatings.
·Improve the moisture retention of coatings.
·Has excellent film forming property.

2. Intracytoplasm adding
·Improve jordaning efficiency, shorten pulping time.
·Regulate electric potential of pulp.
·Improve the retention rate of additives, fillers etc.

3. Top sizing
·Has excellent rheology and film forming property.
·Reduce air hole on paper surface.
·Improve the brightness and gloss of paper.
·Enhance the stiffness and smoothness of paper.
·Increase the surface strength and abrasion resistance of paper.
