Ethyl Cellulose (EC) is a highly versatile cellulose ether with a wide range of applications across industries, from pharmaceuticals and inks to personal care and electronics. For procurement managers and R&D scientists, understanding the various viscosity grades and their specific applications is key to making informed purchasing decisions. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier in China, offers a comprehensive portfolio of Ethyl Cellulose to meet diverse industrial needs.

Ethyl Cellulose is characterized by its physical form (typically a white to slightly yellow powder or granules), its insolubility in water, and its solubility in a variety of organic solvents. Its performance characteristics, such as film-forming ability, water resistance, and binding capacity, are influenced by its molecular weight and degree of substitution, which directly correlate to its viscosity. When you look to buy Ethyl Cellulose, paying attention to these viscosity grades is essential.

Commonly available viscosity grades, such as 4cps, 7cps, 20cps, 50cps, 100cps, 200cps, and 300cps (measured as Brookfield viscosity at 25°C in a 2% solution), are critical for tailoring formulations. For instance:

Low Viscosity Grades (e.g., 4cps, 7cps, 20cps): These grades are often preferred for applications requiring good flow and penetration. In printing inks, they can help achieve optimal viscosity for smooth transfer and improved print definition. In certain pharmaceutical coatings, lower viscosity might be used for thinner, more permeable films.

Medium Viscosity Grades (e.g., 50cps, 100cps, 200cps): These grades offer a balance between flow and film strength, making them highly versatile. They are excellent for general-purpose tablet binding and coating in pharmaceuticals, providing good film integrity and controlled release properties. In inks, they can contribute to increased viscosity and better adhesion.

High Viscosity Grades (e.g., 300cps): Higher viscosity grades are typically used when significant thickening or binding strength is required. In pharmaceuticals, they can be crucial for creating robust matrix systems for sustained drug release or as binders in granulation processes where particle cohesion is paramount. They might also be used in specialized coatings requiring increased film strength.
