CMC is an organic compound, a carboxymethyl derivative
of cellulose, and the most important ionic cellulose
adhesive. CMC is usually an anionic polymer compound
produced by the reaction of natural cellulose with caustic
soda and monochloroacetic acid, with molecular weights
ranging from several thousand to one million. CMC is a
white fibrous or granular powder that is odorless, odorless,
and hygroscopic. It is easily dispersed in water to form a
transparent colloidal solution.

1. Used for oil and gas drilling, well digging, and other engineering projects.
2. CMC is used as a sizing agent in the textile and dyeing industries, as well as in the light yarn sizing of strong fabrics such as cotton, silk and wool, chemical fibers, and blends.
3. CMC used in the paper industry can be used as a paper smoothing agent and sizing agent. Adding 0.1%~0.3% CMC to the pulp can enhance the tensile strength of the paper by 40%~50%, increase the compressive strength by 50%, and increase the kneading ability by 4-5 times.
4. CMC can be added to synthetic detergents as a dirt adsorbent; The glycerol aqueous solution of daily chemicals such as toothpaste industry CMC is used as a gum base for dental sounds.
5. Used in the ceramic industry as an adhesive, plasticizer, suspending agent, and fixing agent for blanks.
6. Used in construction to improve water retention and strength.
