Applications
Pharmaceuticals
Ethyl cellulose (EC) serves multiple functions in pharmaceuticals, including acting as a film former, binder, dispersing agent, stabilizer, water retention agent, and controlled-release agent.
Coating
Ethyl cellulose (EC) can be used in printing and coating applications, producing films with high gloss, excellent smoothness, and good flexibility.
Plastic
EC can be incorporated into plastic powders, making them easier to shape and improving their resistance to low temperatures.
In other industry
Ethyl hydroxyethyl cellulose (EC) is applied as a temporary coating for fluorescent lamp tubes, increasing the viscosity of phosphor and strengthening the glass surface. It is also used in electrically conductive printing inks for the base layer in integrated circuits.
