CMC-NH4 for Advanced SCR Denitration Catalysts & High-Performance Ceramic Applications
Ammonium Carboxymethyl Cellulose (CMC-NH4) is an ammonium salt of carboxymethyl cellulose produced through chemical modification of natural cellulose.
It is a white, odorless, non-toxic powder with excellent water solubility. When dissolved in water, it forms a stable and highly viscous solution with strong thickening, binding, and suspension properties.
Compared with conventional Sodium Carboxymethyl Cellulose (CMC-Na), CMC-NH4 offers significant advantages in high-temperature applications due to its:
- Lower inorganic residue after combustion
- Absence of sodium contamination
- Better compatibility with catalyst formulations
- Cleaner burnout performance
Product Name: Ammonium Carboxymethyl Cellulose
Abbreviation: CMC-NH4
CAS No.: 9085-26-1
