Acid-alkali Tolerance Stable Carboxymethyl Cellulose Ammonium

CMC-NH4(Carboxymethyl Cellulose Ammonium) - Introduction

CMC-NH₄ (Carboxymethyl Cellulose Ammonium) is a water-soluble polymer derivative prepared by etherification modification of natural cellulose. As the ammonium salt form of carboxymethyl cellulose (CMC), it has become a core functional additive in multiple industries due to its unique chemical structure and excellent performance. With a CAS number of 9086-60-6, it is a new-type material integrating environmental protection properties and technical advantages.

 1. Stable Performance & Strong Adaptability

     It appears as white to light yellow powder, easily soluble in water to form a uniform viscous system. The pH value of 1% aqueous solution is stably maintained at 6.5–8.0, with a viscosity range of 1000–3000 mPa·s (25℃). It features excellent batch-to-batch uniformity and weather resistance, is not easily degraded under high-temperature conditions, and has both acid-alkali tolerance and hydrolysis-resistant stability.

 2. Excellent Bonding & Film-forming Effect

     It has super strong adhesiveness and film-forming property, which can effectively bond various substrates and form a dense and uniform protective film. In the molding process, it can significantly improve the mechanical strength of products, with little residue after calcination and no hidden danger of metal ion residue.

 3. Environmentally Friendly & Reliable Quality

     Made from natural renewable refined cotton, it is green and degradable, non-toxic and harmless, and complies with environmental protection standards of multiple industries. It is especially suitable for working conditions sensitive to metal ions.

 4. Diversified Functions & Synergistic Efficiency Improvement

     It integrates multiple functions such as suspension stabilization, nutrient retention and anti-caking. In different application scenarios, it can achieve multiple values of efficiency enhancement, quality improvement and consumption reduction.
