Hygroscopic, insoluble Alcohol, soluble in water, formic acid, formaldehyde, dimethylsulfoxide, dimethylformamide, dimethylacetamide and other solvents, HEC does not ionize in water, has good acid and alkali resistance, and does not react with heavy metals Precipitation, when pH<3, will acidolyze to reduce the viscosity of its aqueous solution. Under the action of strong alkali, HEC will undergo oxidative degradation, and the viscosity of its aqueous solution will decrease due to the action of heat and light, and it will be stable in the range of pH 6.5-8.0. The aqueous solution of HEC can be miscible with most water-soluble glues and water-soluble resins, and a clear and uniform high-viscosity solution can be obtained through the combination of secondary bonds or chemical bonds. It can be miscible with water-soluble resins such as gum arabic, and partially miscible with gelatin, starch, PVA, etc.
HEC has good film-forming properties. Its film is clear, transparent, light-resistant, and has excellent flexibility and oil resistance. Adding glycerin, ethanolamine, mannitol and sulfonated castor oil can make the HEC film more flexible and extensible. , and improves adhesion to glass, metal, fiber and other surfaces.

As top of hydroxyethyl cellulose manufacturers in China, KimaCell® HEC DR300 Hydroxyethyl cellulose is widely used in oil extraction, HEC can be used as drilling, well completion and cementing aids to greatly increase the drilling depth to 6000m. HEC is used as a mud thickener, which has the characteristics of good thickening effect, strong sand suspension, good heat resistance, high salt capacity, small pipeline resistance, less liquid loss, fast gel breaking and low residue.
In addition, HEC can be used as an excipient for tablet coating and a thickener for liquid medicine in the pharmaceutical industry, and as an embryo bonding agent, pore-forming agent, water-retaining and anti-cracking agent and glaze dispersant in the ceramic industry; In agriculture, it is used as grass seed binding agent, seed treatment and pesticide suspending emulsifier.
