CAS No.: 9000-11-7
Molecular Formula: [C6H7O2(OH)2CH2COONa]n
Structural Formula:
Property:
CMC is a cellulose derivative obtained by chemically modificating the natural cellulose. It is one of the most important water soluble polymers with many advantages that other natural or synthetic glues do not have. CMC is white and flowing fine powder, which is tasteless, smelless, mould-proof, non-toxic, non-flammable and easily dissolved in water to become tran***rent viscose solution. Its solution has good properties of thickening, adhering, emulsifying, and stabilizing. membrane forming, moisture-holding, shape-holding, dispersing and anti-enzyme. The solution of CMC can be mixed with dissolvable animal glues, glycerin, sobbitol, Arabic gum, pectin, xanthic gum and dissolvable starch.
