Applications
Pharmaceuticals
Ethyl cellulose (EC) can be used as film former, binder, dispersing agent, stabilizer, water retention agent and controlled release agent in many kinds of medicine.
Coating
Ethyl cellulose (EC) can make up some printing and coating, the coating films have good glossiness and excellent slickening capability and flexibility.
Plastic
Ethyl cellulose (EC)can make up the plastic powder which is easy to take shape, improve cold-resistant property and so on.
In other industry
Ethyl hydroxyethyl cellulose(EC) is used as temporary coating for fluorescent lamp tube, to raise the viscosity of phosphor and harden the glasses' surface. In addition, it is used in electricity conductive printing ink which is used in the basement flake in integrated circuit.
