1. HEC is soluble in hot or cold water, and does not precipitate at high temperature or boiling, so it has a wide range of solubility and viscosity characteristics, and non thermal gel;
2. Its non-ionic type can coexist with other water-soluble polymers, surfactants and salts in a wide range, and it is an excellent colloid thickener containing high concentration of dielectric solutions;
3. The water retention capacity is twice as high as that of methyl cellulose and has good flow regulation;
4. Compared with the recognized methylcellulose and hydroxypropylmethylcellulose, HEC has the worst dispersion ability, but the strongest protective colloid ability.
