Good Water Retention, Uniform Drying, And Improved Yield CMC-NH4
Product Features
Carboxymethyl cellulose ammonium (CMC-NH₄) is a high-performance additive for ceramic production. It has strong adhesion, water retention and crack resistance, improves slurry rheology, and has a clean and residue-free high-temperature burn-off effect. It enhances the strength of the green body and the yield, and is suitable for various ceramic forming processes.

Advantages:
- Strong adhesion: Improves green body strength, reduces cracking, chipping, and deformation.
- Superior water retention: Delays moisture loss, prevents drying cracks, and improves yield.
- Easy molding: Optimizes slurry rheology, making extrusion/slurry injection smoother and preventing mold clogging.
- Clean sintering: Completely burns off at high temperatures, resulting in near-zero residual carbon, preventing blackening and pore clogging.
- High purity: Free from impurities, does not affect ceramic color and performance.
