Carboxymethyl cellulose (CMC) is a water-soluble polymer widely used in the ceramic, paint, and rubber industries for its excellent thickening, binding, and stabilizing properties. In ceramics, it improves green strength and workability of clay bodies. In paints, CMC acts as a viscosity modifier, enhancing application consistency and film stability. In rubber applications, it serves as a processing aid, promoting better dispersion of fillers and improved mechanical properties.
