For any buyer in the chemical industry, understanding product specifications is fundamental to ensuring the suitability and performance of a raw material. Cellulose Acetate (CAS 9004-35-7) is no exception, and its diverse applications hinge on specific, measurable properties. NINGBO INNO PHARMCHEM CO.,LTD., as a reputable manufacturer and supplier, is committed to providing clarity on these critical specifications, helping you to confidently purchase the right grade for your needs.

When considering Cellulose Acetate, several key parameters are crucial for formulators, R&D scientists, and procurement specialists. These typically include:

  • Combined Acetate Value (%): This indicates the degree of acetylation, directly influencing the solubility, film-forming properties, and reactivity of the Cellulose Acetate. For example, a higher value might be preferred for certain plastic formulations.
  • Viscosity (sec): Viscosity is a measure of flow resistance and is vital for applications like membrane production or solvent-based coatings. Different application requirements will necessitate different viscosity ranges.
  • Free Acid (%): The presence of free acid can impact the stability and compatibility of Cellulose Acetate in formulations. Low free acid content is generally desired, especially for pharmaceutical applications.
  • Moisture (%): Controlling moisture content is important for storage stability and processing. High moisture can affect the physical properties and handling of the powder.
  • Filter Value (g/70’): Particularly relevant for membrane applications, the filter value indicates the material's ability to form a filter with specific performance characteristics.
  • Ash (%): Ash content represents inorganic impurities. Low ash content is indicative of high purity, which is essential for sensitive applications.
  • Fe (%): Iron content is another purity indicator, especially critical in pharmaceutical or electronic-grade materials.
