CMC-NH4 | Ammonium Carboxymethyl Cellulose for SCR Catalyst Binder and Ceramic Applications

Ammonium Carboxymethyl Cellulose (CMC-NH4) is a high-performance cellulose derivative developed for advanced ceramic processing and catalyst manufacturing. It is an ammonium salt of carboxymethyl cellulose, produced through chemical modification of natural cellulose.

CMC-NH4 is a white, odorless, water-soluble powder with excellent binding, thickening, dispersion, and rheological control properties. It is specially designed for applications requiring low ash content, sodium-free composition, and clean thermal decomposition performance.

Compared with traditional Sodium Carboxymethyl Cellulose (CMC-Na), CMC-NH4 provides better performance in high-temperature processes, making it an ideal additive for SCR denitration catalysts, honeycomb ceramics, battery materials, and electronic ceramics.

CMC-NH4 produces minimal inorganic residue after high-temperature combustion.

Advantages:

• Reduces contamination during catalyst production
• Improves final product purity
• Suitable for high-temperature calcination
• Supports clean ceramic processing

Unlike CMC-Na, CMC-NH4 contains no sodium ions, avoiding unwanted alkali metal introduction into catalyst systems.

Benefits:

• Better compatibility with SCR catalyst formulations
• Reduces risk of catalyst poisoning caused by sodium contamination
• Suitable for high-purity ceramic materials

CMC-NH4 provides outstanding processing performance during catalyst and ceramic forming processes.

It can improve:

• Green body strength
• Material cohesion
• Extrusion smoothness
• Slurry stability
• Product consistency

This makes it an effective binder and processing aid for honeycomb structures and catalyst blocks.

During calcination and sintering, CMC-NH4 decomposes efficiently with low residue.

Advantages:

• Cleaner burnout process
• Reduced impurities after firing
• Improved ceramic structure stability

CMC-NH4 is widely used as a binder and extrusion additive in SCR catalyst manufacturing.
