Carboxymethyl Cellulose (CMC)

What is CMC (Carboxymethyl Cellulose)?

Carboxymethyl Cellulose (CMC) is an anionic water-soluble polymer derived from refined cellulose. It is widely used as a thickener, stabilizer, binder, water retention agent, and film-forming agent. CMC offers excellent dispersibility and rheological control in both aqueous and semi-aqueous systems, making it a versatile additive across multiple industries.


Hehui Chemical offers high-quality CMC grades with controlled viscosity, purity, and substitution levels to meet the specific requirements of each application.

Product Advantages
Product Advantages

Carboxymethyl Cellulose (CMC) is a high-performance, water-soluble cellulose ether derived from natural plant fibers. It is valued for its versatility, consistent quality, and environmental safety. Below are the key benefits that make CMC a preferred additive across various industries:

1. Outstanding Water Retention

Helps maintain moisture in cement, paper, and ceramic systems, ensuring better curing, coating uniformity, and product stability.

2. Effective Thickening and Rheology Control

Provides reliable viscosity control in both low and high-shear systems, ideal for coatings, detergents, and printing pastes.

3. Excellent Film-Forming Capability

Forms smooth, continuous films on paper and textiles, enhancing surface strength, gloss, and print quality.

4. Strong Binding and Suspension Power

Improves structural integrity in tablets, ceramics, and coatings, while keeping solids evenly suspended to prevent settling.

5. Salt and Alkali Resistance

Maintains stable performance in high-pH environments, such as tile adhesives, detergents, and oilfield fluids.
