The carboxymethylation reaction is one of the etherification techniques. Carboxymethylation of cellulose gives carboxymethyl cellulose (CMC). Its aqueous solution has the functions of thickening, film formation, adhesion, moisture retention, colloid protection, emulsification and suspension.
It is widely used in petroleum, food and medicine. The textile, paper and other industries are among the most important cellulose ethers.

We can supply CMC according to customer's requirement.
Application:
CMC Used in Paper-making industry,
It's 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 a molding reagent. In paper coating, CMC also helps the dispersion and fluidity of paint, improves the appearance of paper and smoothness, and upgrades optical performance and printing adaptability.
