CMC-NH4 | Ammonium Carboxymethyl Cellulose for SCR Catalyst Production and Ceramic Processing

Ammonium Carboxymethyl Cellulose (CMC-NH4) is a high-performance cellulose-based functional additive specially developed for SCR denitrification catalyst manufacturing, honeycomb ceramic production, and advanced material processing.

CMC-NH4 is the ammonium salt derivative of carboxymethyl cellulose (CMC), produced through controlled chemical modification of natural cellulose. Unlike conventional sodium-based cellulose additives, CMC-NH4 provides a sodium-free composition, ultra-low ash content, excellent binding ability, and clean thermal decomposition characteristics, making it highly suitable for high-purity ceramic and catalyst applications.

CMC-NH4 is supplied as a white, odorless, water-soluble powder. After dissolution, it forms a stable polymer solution with excellent:

• Binding performance
• Rheological control
• Slurry stabilization
• Dispersion capability
• Extrusion improvement
• Green body strength enhancement

Due to its unique chemical structure and low inorganic residue characteristics, CMC-NH4 is widely used as a binder and processing aid in:

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

Compared with traditional Sodium Carboxymethyl Cellulose (CMC-Na), CMC-NH4 offers significant advantages for high-temperature ceramic and catalyst manufacturing:

CMC-NH4 helps manufacturers reduce impurity introduction and maintain the purity and stability required for advanced catalyst systems.

CMC-NH4 produces extremely low inorganic residue during calcination and high-temperature firing processes.

• Minimizes contamination in ceramic systems
• Improves catalyst material purity
• Supports cleaner sintering processes
• Suitable for precision ceramic manufacturing

The low ash characteristic makes CMC-NH4 particularly suitable for SCR catalysts and high-performance ceramic applications where impurity control is critical.

Unlike CMC-Na, CMC-NH4 does not introduce sodium ions into catalyst or ceramic formulations.

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

CMC-NH4 provides strong binding capability and optimized rheological control during catalyst forming and ceramic extrusion processes.

It improves:

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

CMC-NH4 enables manufacturers to achieve more stable extrusion processes and consistent final product quality.

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

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

CMC-NH4 is widely used as a binder, extrusion aid, and rheology modifier in selective catalytic reduction (SCR) catalyst production.

• V₂O₅-WO₃/TiO₂ catalysts
• Honeycomb SCR catalyst blocks
• Plate-type SCR catalysts

• Improves extrusion performance
• Enhances catalyst green strength
• Promotes uniform honeycomb structures
• Improves dimensional stability
• Reduces residue after calcination
• Enhances production consistency

CMC-NH4 is especially suitable for manufacturers producing high-performance SCR catalysts for industrial NOx emission control systems.

CMC-NH4 is suitable for the production of:

• Automotive exhaust catalyst substrates
• Diesel particulate filters (DPF)
• Industrial honeycomb ceramic structures

• Stable extrusion behavior
• Improved pre-firing mechanical strength
• Better forming performance
• Enhanced dimensional precision
• Consistent processing quality

CMC-NH4 can function as a binder and rheology control additive in electrode material preparation.

• Silicon-based anode materials
• Graphite electrode systems
• Battery slurry preparation

• Improves binder efficiency
• Controls slurry viscosity
• Enhances particle dispersion
• Improves coating uniformity

CMC-NH4 is suitable for high-purity ceramic applications including:

• Alumina ceramics
