CMC Sodium Carboxymethylcellulose paper making grade Auxiliary Agents

CMC is a kind of important cellulose ether and a good water-soluble polyanionic compound obtained from chemically modified natural fibers, soluble in cold water. It has unusual and extremely valuable comprehensive physical and chemical properties such as emulsifiablity, dispersion, solid dispersion, non-perishability, physiological harmlessness, etc., and is a kind of widely-used natural polymer derivatives.
The superior properties of Na CMC include: thickening, water retention, metabolism inert, film formability, dispersion stability, etc. It can be used as thickeners, water retention agents, binders, lubricants, emulsifiers, assistant deflocculants, tablet substrate, biological substrates and carriers of biological products.
 
In making paper, CMC is used in making pulp so as to improve the retention rate and increase humidity and strength; when used in surface sizing, CMC can improve internal adhesion, decrease printing dust and enhance printing quality as molding reagent. In paper coating, CMC also helps the dispersion and fluidity of paint, improves appearance of paper and smoothness, upgrades optical performance and printing adaptability.
Addition: 0.3-1.5%. 
Kindly contact us for specification and information about any specific grade of CMC other than mentioned in the above table.
In paper making industry, FUXIN® CMC is used to make the paint for coated paper, as additive in wet-end and sizing agent for surface. We have different paper making grades of CMC products to satisfy different customers' requirements.
 
Applications in Coated Paper
1. Control and adjust the flowing property of paint and the sispersibility of the pigment, increase the solid content of paint.
2. Strengthen the water retention value of the paint and avoid the moving of adhesive, so that it can improve the leveling of the paint and quality of the coating.
3. Give good stability to the paint, keep the homogeneity of the paint system.
4. Excellent film forming property, improve the gloss of the coating.
5. Improve the retention rate of the brightener, and increase the whiteness of the paper.
Applications as Wet-end Additive
1. Excellent dispersibility helps the shaping of paper and improves the evenness.
2. Improve the inner bond force of cellulose, increase the physical strength of the paper.
3. Enhance the sizing effect.
4. Increase the retention of additives, stuffing and tiny cellulose.
Applications in Surface Sizing
1. Increase the fluffing speed of paper obviously and improve the ink absorbability.
2. Excellent flowing and film forming property enhance the stiffness and smoothness of paper.
3. Improve the surface strength and aeration, control curling.
