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

Molecular Formula:
C8H15NO7
