Ammonium Carboxymethyl Cellulose (CMC-NH4) is a high-performance cellulose derived from natural cellulose through chemical modification. It is an ammonium salt form of carboxymethyl cellulose, specially developed for high-temperature ceramic processing and catalyst manufacturing.
CMC-NH4 appears as a white, odorless, non-toxic powder with excellent water solubility. After dissolution, it forms a stable viscous solution with outstanding binding, thickening, dispersion, and rheological control properties.
Compared with conventional Sodium Carboxymethyl Cellulose (CMC-Na), CMC-NH4 provides superior performance in high-temperature applications due to its:
- Ultra-low inorganic residue after combustion
- Sodium-free composition
- Excellent compatibility with catalyst formulations
- Clean thermal decomposition characteristics
These advantages make CMC-NH4 an ideal functional additive for SCR denitration catalysts, honeycomb ceramics, lithium battery materials, and electronic ceramic applications.
