CMC-NH4 Manufacturer | Ammonium Carboxymethyl Cellulose Supplier From China

Shanghai Prior Chemical specializes in the development, production and global supply of CMC-NH4 (Ammonium Carboxymethyl Cellulose), a high-purity cellulose specifically designed for high-temperature ceramic and catalyst applications.

CMC-NH4 is widely used as a low-ash, sodium-free binder in SCR denitrification catalysts, honeycomb ceramics, lithium battery materials, phosphor powders and precision electronic ceramics.

Ammonium Carboxymethyl Cellulose (CMC-NH4) is an anionic cellulose derivative produced by chemical modification of natural cellulose.

It appears as a white or slightly yellow powder, odorless, tasteless and non-toxic. It readily dissolves in cold water to form a transparent and highly viscous solution.

Compared with conventional Sodium Carboxymethyl Cellulose (CMC-Na), CMC-NH4 provides significant advantages in high-temperature applications due to its extremely low ash residue and absence of alkali metal contamination.

Chemical Structure:

C6H7O2(OH)2OCH2COONH4

Molecular Formula:

C8H15NO7

Ash content typically below 0.5%, minimizing contamination after calcination.

No sodium or potassium ions remain after decomposition, protecting catalyst active sites.

Provides outstanding:

• Adhesion

• Thickening

• Suspension

• Dispersion

• Water retention

• Film-forming capability

Suitable for high-temperature sintering and calcination processes.

Helps improve extrusion performance, green body strength and production consistency.
