Ethyl Cellulose(EC) is a kind of white grains or powder ,having no smell or taste.Its 5% soliquoid shows neutral to litmus test paper. Its specific density 1.07-1.18,heat distortion point:135~155 degree centigrade ,and fire point:330~360 degree centigrade Ethyl Cellulose has good stability against light ,heat,oxygen and wetness, and is stable to chemicals. It is resistant to alkali, dilute acid and salting liquid ,soluble in some organic solvents ,ether,ketone,ester,aromatic hydrocarbon and halohydrocarbon,etc ,and compatible with many celluloses, resin and nearly all plasticizers.Ethyl Cellulose has low combustibility,small hydroscopicity and good electric behavior.Its thin film and plastics have good mechanical strength and flexibility in a wide range of temperature.
Ethyl cellulose is mainly used as tablet adhesive and thin film coating material, etc. It is also used as retarding agent for aggregate to make various types of aggregate slow-release pills; It can even be used as adhesive, slow-release agent and moisture repellant agent for vitamine pills and mineral pills.
