Key Advantages Provided by CMC
Enhanced Paper Strength
Carboxymethyl Cellulose significantly improves the tensile strength, folding resistance, and overall toughness of paper by strengthening inter-fiber bonds, contributing to better paper durability.
Improved Uniformity and Surface Finish
As a dispersant, CMC ensures even distribution of fibers and fillers, leading to improved paper formation, flatness, and a smoother surface finish, which is essential for high-quality printing.
Superior Coating Performance
When used as a coating agent, CMC improves the gloss, smoothness, and printability of paper. Its film-forming properties create a dense, uniform coating layer that enhances the visual appeal and print quality.
Key Applications
Pulp Enhancement
Adding CMC to the wet end of papermaking effectively improves fiber bonding and paper strength, and can reduce filler loss, showcasing its role in optimizing pulp processing.
Surface Sizing
CMC serves as an excellent surface sizing agent, improving paper strength, smoothness, and printability, while reducing linting and powdering, making it a key component for achieving desired paper characteristics.
Coating Agent
In paper coatings, CMC improves water retention and rheology, aids pigment dispersion, and enhances the finish, smoothness, and optical performance of coated papers and boards.
Dispersant
As a dispersant, CMC prevents aggregation of fibers, fillers, and pigments, ensuring paper uniformity and improving the light shielding and overall quality, especially for specialty papers.
