KimaCell® EC N20 ethyl cellulose is also called cellulose ether, referred to as EC.
Molecular composition and structural formula: [C6H7O2(OC2H5)x(OH)3-x]n.
Appearance: white to light yellow or light gray fluid powder or granules, odorless, tasteless, non-toxic, thermoplastic for EC with a degree of substitution above 1.5.
Properties: The 5% suspension of EC is neutral to litmus paper; the softening point is 135~155°C, the melting point is 165~185°C, the pseudo specific gravity is 0.3~0.4g/cm3, and the relative density is 1.07~1.18g/cm3 , ignition point: 330-360OC; EC has good stability to light, heat, oxygen and humidity, stable to chemicals, not easy to burn; can withstand strong alkali, dilute acid and salt solution, EC is generally insoluble in water, but soluble in different Non-ionic cellulose ethers in organic solvents, such as alcohols, ethers, ketones, aromatics, halogenated hydrocarbons and other organic solvents; compatible with many celluloses, resins and almost all plasticizers; ethyl cellulose It has low flammability, low hygroscopicity, good electrical properties, and its films and plastics have good mechanical strength and flexibility in a wide temperature range.

KimaCell® EC N20 ethyl cellulose is used in various coatings, such as metal surface coatings, paper product coatings, rubber coatings, hot-melt coatings and integrated circuits; for inks, such as magnetic inks, gravure and flexographic printing inks; as cold-resistant materials; for Special plastics and special precipitation, such as rocket propellant coating tape; used in insulating materials and cable coatings; used in polymer suspension polymerization dispersants; used in cemented carbide and ceramic adhesives; used in textile industry as printing color Pulp, etc.
The most commonly used mixed solvents for ethyl cellulose (DS: 2.3~2.6) are aromatic hydrocarbons and alcohols. Aromatics can be benzene, toluene, ethylbenzene, xylene, etc., with an amount of 60-80%; alcohols can be methanol, ethanol, etc., with an amount of 20-40%. Slowly add EC to the container containing the solvent under stirring until it is completely wetted and dissolved.
