HEC HS200000

KimaCell^® HEC HS200000 Hydroxyethyl cellulose ether has good thermal stability below 140 ℃ and does not produce precipitation under acidic conditions. HEC aqueous solution is a fluid with high pseudoplasticity, and its apparent viscosity decreases with the increase of shear rate. The pseudoplasticity of low molecular weight solution is close to that of Newtonian fluid, and its solution viscosity changes little in the range of pH 2-12, but exceeds Viscosity decreases in this range. HEC has excellent salt tolerance for electrolytes, and will not cause changes in viscosity due to precipitation or sedimentation residues due to high concentrations of salt in the system. The water retention capacity of HEC is twice as high as that of methyl cellulose (MC), and it has good flow regulation. When the temperature of the solution increases, the viscosity will decrease, and the viscosity will increase when the temperature decreases.
