Ethyl Cellulose for industrial Usage
¡¾Introduction¡¿
Name: Ethyl Cellulose
Abbreviation: EC
Structural formula:
In the formula, n stands for degree of polymerization and R for ¨CH or ¨CC2H5.
Characteristics:
Ethyl Cellulose 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 to light, heat, oxygen and wetness, and is stable to chemicals. It is resistant to alcali, dilute acid and salting liquid, soluble in some organic solvents, such as alcohol, ether, ketone, ester, aromatic hydrocarbon and halohydrocarbon, etc, and co***tible to 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.
