Molecular formula : [C6H7O2 (OH) 3n (OC2H5) n] x
MW : No
CAS No. :9004-57-3
nature : the white, granular or powder. Softening point 100-130 ° C and relative density of 1.07-1.18, refractive index 1.47. Solubility with cellulose hydroxy-ethoxy replaced by the degree to which different. General merchandise-ethoxy-47% -48%. Most soluble organic solvent, with the resin, wax and oil mixed plasticizer, the alkali and acid ineffective and do not dissolve in water. Ethyl cellulose healthy, and at low temperatures remain fully soft properties, thermal stability, good-will not be affected by the impact of color, with little sense of adhesive or sticky hair, size, stability, and the miscibility of wax, and burning ash rarely replace varying degrees of ethyl cellulose, There are also differences in performance.
Preparation Methods : refining and pulp or cotton fiber alkaline sodium hydroxide-made. Then the pressurized reactor convinces alkaline cellulose and ethylene oxide reaction to glucose within the three hydroxyl all or part replacement for ethoxy. Reaction products with hot water washing, drying, obtained ethyl cellulose.
purposes : ethyl cellulose widely used coating. Also used for metal stamping parts of the basic solid lubricant materials. In micro-circuit printing, as ethyl cellulose containing reagent. In the radio industry, as senior insulation materials and protective coating as a special film, as rocket propellant packages cladding. As cable, paper, textiles, and other hot-melt glue to the agent and coating, extrusion line for the plastic insulation and for the toughness intensifier. Pigments can be used for base material for printing inks, plastics molding powder used for explosive fuses, and for vitamin formula so. For the metal parts prior to the use of anti-corrosion and anti-destroyed peelable protective layer, are also used for protection of fragile glassware of peeling paint. In adhesives, textile and fiber, medicine and food, and other industries, there are multiple uses. Industrial grade ethyl cellulose used in the coatings (gel-coating, hot melt coating), Ink (screen printing ink, ink brush photogravure), adhesives, paint, etc. paste. Senior Commodities will be used for medicine, cosmetics and food products, such as tablet drug packaging materials, long-acting formulations used as binder.
