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

Ammonium Carboxymethyl Cellulose (CMC-NH4) is a high-performance cellulose derivative developed for SCR denitrification catalyst manufacturing and advanced ceramic processing.

CMC-NH4 is the ammonium salt form of carboxymethyl cellulose, produced through chemical modification of natural cellulose. It is designed as a functional additive for applications requiring high purity, low residue, excellent binding performance, and stable processing properties.

CMC-NH4 is a white, odorless, water-soluble powder that forms a stable viscous solution after dissolution. It provides excellent:

• Binding performance
• Rheological control
• Dispersion ability
• Extrusion improvement
• Slurry stability

Compared with traditional Sodium Carboxymethyl Cellulose (CMC-Na), CMC-NH4 offers significant advantages in high-temperature ceramic applications, including:

• Sodium-free composition
• Ultra-low ash content
• Cleaner thermal decomposition
• Excellent compatibility with catalyst systems

These properties make CMC-NH4 an ideal binder and processing additive for:

• SCR denitrification catalysts
• Honeycomb ceramic substrates
• Automotive emission catalyst carriers
• Lithium battery materials
• Electronic ceramic components

1. Ultra-Low Ash Content

CMC-NH4 generates minimal inorganic residue during high-temperature combustion and calcination processes.

Benefits:

• Reduces impurity introduction into ceramic systems
• Improves catalyst material purity
• Supports cleaner sintering processes
• Suitable for high-temperature applications

The low ash characteristic makes CMC-NH4 especially suitable for precision ceramic and catalyst manufacturing.

2. Sodium-Free Composition

Unlike CMC-Na, CMC-NH4 does not introduce sodium ions into the formulation.

Advantages:

• Avoids alkali metal contamination
• Improves compatibility with SCR catalyst formulations
• Supports high-purity ceramic production
• Helps maintain catalyst performance stability

3. Excellent Binding and Extrusion Performance

CMC-NH4 provides effective binding and rheological control during catalyst and ceramic forming processes.

It improves:

• Raw material cohesion
• Slurry stability
• Extrusion smoothness
• Green body strength
• Shape retention
• Dimensional accuracy

CMC-NH4 helps manufacturers achieve more stable production processes and improved product consistency.

4. Clean Thermal Decomposition

During calcination and sintering, CMC-NH4 decomposes efficiently with minimal residual impurities.

Advantages:

• Cleaner burnout process
• Reduced contamination after firing
• Improved ceramic structure stability
• Suitable for precision material processing
