For ink manufacturers, a deep understanding of the technical specifications of raw materials is fundamental to achieving consistent product quality and optimal performance. Ethyl Cellulose (EC) is a key chemical auxiliary used to enhance printing inks, and its properties are defined by specific technical parameters. NINGBO INNO PHARMCHEM CO.,LTD., a leading chemical supplier, provides insight into these specifications and offers high-quality EC to meet your formulation needs.

The primary technical specifications for Ethyl Cellulose, identified by CAS No. 9004-57-3, revolve around its ethoxy content and viscosity. These two factors significantly influence how EC will behave as a binder, viscosity modifier, and film-former in your printing ink formulations, whether for screen printing, magnetic inks, flexographic, or gravure applications.

Ethoxy Content: This refers to the percentage by weight of ethoxy groups (-OC2H5) in the cellulose molecule. The ethoxy content directly impacts the solubility of EC in different solvents and its film-forming capabilities. Typical ranges, as seen in products from manufacturers like ours, might be around 45.0% to 49.5% for standard grades, with variations possible for specialized applications. A precise ethoxy content ensures predictable interactions with other ink components and solvents.

Viscosity: Viscosity is measured in millipascal-seconds (mPas) and indicates the resistance to flow. Ethyl Cellulose is available in a wide range of viscosity grades, from low (e.g., 6-300 mPas) to high (e.g., 250 mPas and above). For ink formulators, selecting the correct viscosity grade is critical for controlling the rheology of the ink. Lower viscosity grades are often preferred for applications requiring fast ink transfer and thin film application, while higher viscosity grades can be used to thicken inks or improve their body and stability. When you purchase Ethyl Cellulose, consult the technical data sheets provided by the supplier to match the viscosity to your specific ink requirements.

Other Important Specifications: Manufacturers also provide information on ash content (typically below 0.4%), moisture content (usually below 3.0%), and appearance (white or yellowish powder or grains). These parameters are indicative of the purity and quality of the Ethyl Cellulose. Sourcing from a reliable supplier in China, such as NINGBO INNO PHARMCHEM CO.,LTD., guarantees that these specifications are consistently met.

Understanding these technical specifications allows ink manufacturers to make informed decisions when buying Ethyl Cellulose. It ensures that the chosen grade will deliver the desired performance, whether it's enhancing print quality, improving ink stability, or providing superior durability.
