Features Of Ashland BLANOSE CMC 7HF PH Carboxymethylcellulose Sodium

  1. High-viscosity, low-salt sodium carboxymethylcellulose optimized for pH-stable performance in neutral to slightly alkaline aqueous systems.

  2. Excellent water solubility and rapid hydration with minimal lumping, enabling efficient dispersion in industrial mixing processes.

  3. Superior film-forming capability and cohesive strength, enhancing binder functionality in coating and ceramic applications.

  4. Consistent rheological profile across batch variations, supporting reproducible process control in high-precision manufacturing.

  5. Non-ionic character combined with anionic charge density provides balanced compatibility with common surfactants, electrolytes, and pigments.

Typical Applications Of Ashland BLANOSE CMC 7HF PH Carboxymethylcellulose Sodium

  1. Ceramic tile adhesives and grouts requiring extended open time and sag resistance.

  2. Water-based architectural coatings and texture finishes for improved leveling and brush drag reduction.

  3. Oilfield cementing slurries as a fluid loss control additive and viscosity modifier.

  4. Pharmaceutical tablet granulation and binder systems compliant with USP/NF monograph requirements.

  5. Textile printing thickeners where stable viscosity under shear and pigment suspension are critical.
