Product Description:

 Product description: 

 

Sodium CarboxymethylCellulose (CMC) is white or yellowish powder that is odorless, tasteless and non-toxic. It has high hygroscopicity and is soluble in water to form a thick liquid. It is a poly anionic electrolyte and not fermented. It has good heat-stability, resistance to salt and film-forming property.

 

Applications

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%.
