Product Description
Product Overview

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

CMC-NH4 is the ammonium salt form of carboxymethyl cellulose, produced through chemical modification of natural cellulose. It is a white, odorless, water-soluble powder with excellent binding ability, rheological control, dispersion performance, and extrusion processing properties.

Compared with conventional Sodium Carboxymethyl Cellulose (CMC-Na), CMC-NH4 offers advantages including sodium-free composition, ultra-low ash content, and cleaner thermal decomposition behavior, making it highly suitable for high-temperature ceramic processing and catalyst production.

CMC-NH4 is widely used as a functional binder and processing additive in:

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

Key Properties of CMC-NH4
1. Ultra-Low Ash Content

CMC-NH4 generates extremely low inorganic residue during high-temperature decomposition.

Advantages:
  • Minimizes contamination during catalyst manufacturing
  • Improves purity of ceramic products
  • Suitable for high-temperature calcination processes
  • Supports cleaner ceramic structures

2. Sodium-Free Composition

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

Benefits:
  • Prevents sodium contamination in catalyst materials
  • Improves compatibility with SCR catalyst formulations
  • Suitable for high-purity ceramic applications
  • Reduces potential impact of alkali metal impurities

3. Excellent Binding and Extrusion Performance

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

It helps improve:

  • Green body strength
  • Particle bonding
  • Extrusion smoothness
  • Slurry stability
  • Dimensional consistency

As a result, CMC-NH4 helps manufacturers achieve stable production of honeycomb structures and catalyst blocks with improved mechanical properties.


4. Clean Thermal Decomposition

During drying, calcination, and sintering processes, CMC-NH4 decomposes efficiently with minimal residue.

Benefits:
  • Cleaner burnout process
  • Reduced impurities after firing
  • Improved ceramic structure stability
  • Better product quality consistency
