Paper Making Grade CMC (Sodium Carboxymethyl Cellulose)


In paper makingindustry, CMC is used to make the paint for coated paper, as additive inwet-end and sizing agent for surface. We have different paper making grades ofCMC products to satisfy different customers’ requirements.

Applications in Coated Paper

1. Control and adjust the flowing property of paint and thedispersibility of the pigment, increase the solid content of paint.

2. Strengthen the water retention value of the paint and avoid themoving of adhesive, so that it can improve the leveling of the paint andquality of the coating.

3. Give good stability to the paint, keep the homogeneity of thepaint system.

4. Excellent film forming property, improve the gloss of thecoating.

5. Improve the retention rate of the brightener, and increase thewhiteness of the paper.

Applications in Surface Sizing

1. Increase the fluffing speed of paper obviously and improve theink absorbability.

2. Excellent flowing and film forming property enhance thestiffness and smoothness of paper.

3. Improve the surface strength and aeration, control curling.

Applications as Wet-end Additive

1. Excellent dispersibility helps the shaping of paper andimproves the evenness.

2. Improve the inner bond force of cellulose, increase thephysical strength of the paper.

3. Enhance the sizing effect.

4. Increase the retention of additives, stuffing and tinycellulose.
