Paper Sizing Agents Carboxymethyl cellulose for paper wet-end additive

CMC displays many excellent performance in paper-making technology. it is higher valued by the majority of paper engineers and is widely used in the production of paper and paperboard, such as paper and paperboard coating process, coating rheology modifier, water - retention agent, film-forming agent, auxiliary adhesives, wet end retention enhancers and surface sizing agents, grinding aids, filler modifier and the flocculating agent which used in waste water treatment etc. We have different paper making grades of CMC to meet the different customers’ requirements.


1 . Enhance cohesion between the fibers, and improve the paper strength.

The pulp sizing function, and the paper with a certain degree of sizing.

2 . Excellent dispersibility helps the shaping of paper and improves the paper evenness.

3 . Internal sizing protector, and promote sizing agents to be distributed evenly on fiber surface;

4 . Delay AKD hydrolysis rate and reduce the possibility of hydrolysis garbage pollution system;

5 . Excellent fine fiber and filler affinity, and improve the one way retention of paper machine and aids retention rate.

6 . Enhance the filler and the fiber fines retention and reduce the white water concentration.


4% Solution Viscosity (mPa.s)≤500
Substitution of degree0.65-1.0
pH value6.0-8.5
Dry reduction %≤10.0
