Ammonium Carboxymethyl Cellulose (CMC-NH4) is a high-purity, alkali-soluble polymeric binder specifically formulated for advanced ceramic manufacturing and environmental catalysis industries. Unlike standard sodium-based binders, this ammonium-based formulation leaves zero metallic residue upon thermal processing, making it an exceptional choice for high-performance applications where purity is critical.

Key Performance Advantages

• Ash-Free Thermal Decomposition: Completely burns out during calcination without leaving residual alkali metal ions, preventing poisoning or degradation of sensitive catalytic systems.

• Superior Rheology Control: Imparts excellent thickening, pseudoplastic flow, and water-retention properties to ceramic slurries and extrusion pastes.

• Enhanced Green Strength: Significantly improves the structural integrity, plasticity, and edge definition of extruded green bodies prior to firing.

• Optimal Solubility: Dissolves readily in aqueous and mild alkali systems, ensuring a homogeneous mixture and smooth extrusion processes.

Primary Applications

• SCR Denitration Catalysts: Serves as a clean, residue-free binder for manufacturing honeycomb-type selective catalytic reduction catalysts used in power plants and industrial emission control.

• Honeycomb Ceramics: Ideal for producing high-cell-density extruded substrates for automotive catalytic converters and industrial heat exchangers.

• Advanced Technical Ceramics: Used in specialized refractory materials, filter elements, and porous ceramic structures requiring high chemical purity.

Typical Technical Specifications

• Appearance: White to off-white fibrous or granular powder

• Purity: High purity grade ($\ge 99\%$ active polymer basis available upon request)

• Solubility: Soluble in water, forming a clear to translucent colloidal solution

• Functionality: Alkali-soluble, non-ionic to weakly anionic binder system
