F.W. of Ethyl cellulose (EC) : Nill
CAS no. of Ethyl cellulose (EC) : 9004-57-3
DOT of Ethyl cellulose (EC) : Nill
NFPA no. of Ethyl cellulose (EC) : 0-0-0
Class no.of Ethyl cellulose (EC) : Nill
UN no. of Ethyl cellulose (EC) : Nill
HS code of Ethyl cellulose (EC) : 39123990
Specific Gravity of Ethyl cellulose (EC) : 1.07-1.18

Ethyl cellulose (EC) is a kind of white grains or powder, having no smell or tastes. Its 5% soliquoid shows neutral to litmus test paper. Its specific density 1.07~1.18, heat distortion point: 135~155degree 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, such as alcohol, 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.

Application of Ethyl cellulose (EC)

Application of EC pharma.grade:

Due to its insolubility in water, 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; as slow-release agent or slow-release pills for compound material when making coat; as microcapsule material to make the medical effect release continuously, and avoid the preaction of water soluble medicine. It can be too used in any type of medicine as dispersing agent, stabilizer and water retention agent to prevent medicine from absorption and deterioration, enhance the safe storage and stability of pills. It can even be used as adhesive, slow-release agent and moisture-repellant agent for vitamine pills and mineral pills.

Application of EC indu.grade:

Ethyl Cellulose is widely used in paints for various products, such as wooden products (furniture), metal surfaces, paper, rubber, thermotropic products and integrated circuits; in ink such as screen printing ink, magnetic ink, intaglio and amine printing ink; as freezing-resistant material and all kinds of precise membrane module used in aviation industry; as the special plastics and precipitate such as rocket propellant coating band; as electrical insulation and cable coating; as high molecular suspension polymerizing and dispersing agent; as adhensive in hard alloy and ceramics; and used as dye printing slurry in textile industry.
