CMC (Carboxymethyl Cellulose)
Ceramics Grade
1. Physical and chemical properties
Carboxymethyl-cellulose Sodium (CMC-Na) 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 or thin yellow and flowing fine powder. It is tasteless, smelless, mould-proof, non-toxic, non-flammable and easily dissolved in water to become transparent viscose solution.
CMC solution has good properties of thickening, adhering, emulsifying, 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.
