Hydroxy Ethyl Cellulose HEC

Quantity:

Hydroxy Ethyl Cellulose HEC

 

Physicochemical Properties

a) Appearance: White to pale yellow color in the state of fibrous or powdery solid. Non-toxic and odorless.

b) Solubility: HEC is soluble in water and insoluble in the normal organic solvents.

c) PH Stability: Within the range of 2-12, the viscosity changes little. PH value out of this range, the viscosity decreases.

d) Property performance: HEC has the property performance of thickening, suspension, adhesive, emulsion, dispersion, water retention and protective colloid. And can be used for the solution preparation of different viscosity.

e) Activity: Being stable at normal temperature and pressure.

-Avoid high temperature, moisture and heat.

-With very good salt solubility for the dielectric, and its aqueous solution allows containing high concentrations of salts and has stable performance.
