Sodium carboxymethyl cellulose(CMC), known as Cellulose gum, is a high-polymer cellulose ether obtained by chemically modifying natural cellulose.CMC is white or milky white fibrous powder or granules, with a density of 0.5-0.7 g/cm3, almost odorless, tasteless, and hygroscopic. CMC-Na is white fibrous or granular powder, odorless, tasteless, hygroscopic.
CMC is Easily dispersed in water to form a transparent colloidal solution, insoluble in organic solvents such as ethanol. Carboxymethyl cellulose is obtained after carboxymethylation of cellulose, and its aqueous solution has the functions of thickening, film formation, adhesion, water retention, colloid protection, emulsification and suspension, and CMC can be used in paints&coatings, food additives, papermaking Additives, flocculants, filter aids, mud conditioners, mud overflow preventionAgents, abrasives, additives for adhesives, etc.
