Sodium Carboxymethyl Cellulose(CMC)
which is obtained by chemical modification of natural cellulose, is a water-soluble cellulose ether. CMC is characterized by odourless, tasteless, and non-toxic with white to off-white powder or granule. It can dissoive in water easily and transfer into colloidal solution, and cannot dissolve in ethanol, etheracetone or other organic solvents. CMC has thickening properties that can be used as water retaining agent, adhesive, emulsifier, and disintegrator. CMC is the carrier of biological products.
When used in coating
CMC has water retention ability, improve the rheological property and water retention of the coating;
Improve the color of paper and the retention rate of whitening agent in paint;
Improve coating content and coating quality;
Make the paper coating more smooth and bright.
When used in pulp
CMC interacts with the fibers in the paper to enhance the physical strength of the paper;
Promote paper forming;
Improve the uniformity of paper.
When used in surface sizing
It can be used as a dispersant to maintain the stability of the whole rubber material and reduce the porosity of paper;
Increase the smoothness and gloss of the paper; Improve paper oil resistance and surface strength;
Improve the printing quality of paper;
Improve wear resistance.
