Product Description
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 atransparent colloidal solution.
