What Is Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose (HEC) is a white or light yellow, odorless, non-toxic fibrous or powdered solid, composed of alkaline cellulose and ethylene oxide (or chloroethanol) It is prepared by etherification reaction and belongs to non-ionic soluble cellulose ethers. Because HEC has good thickening, suspending, dispersing, emulsifying, bonding, film-forming, protecting moisture and providing protective colloids, it has been widely used in petroleum exploration, coatings, construction, medicine and food, textiles, papermaking, and polymers. Polymerization and other fields. 40 mesh sieving rate ≥99%

Product performance

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

Application field

Used as adhesive, surface active agent, colloidal protective agent, dispersant, emulsifier and dispersion stabilizer, etc. It has a wide range of applications in coatings, inks, fibers, dyeing, papermaking, cosmetics, pesticides, mineral processing, oil extraction and medicine.

1. Generally used as thickeners, protective agents, adhesives, stabilizers and additives for preparing emulsions, gels, ointments, lotions, eye clearing agents, suppositories and tablets, and also used as hydrophilic gels and skeletons Materials, preparation of matrix-type sustained-release preparations, and can also be used as stabilizers in food.
2. Used as sizing agent in textile industry, bonding, thickening, emulsifying, stabilizing and other additives in electronics and light industry.
3. It is used as a thickener and fluid loss reducer for water-based drilling fluids and completion fluids. The thickening effect is obvious in brine drilling fluids. It can also be used as a fluid loss control agent for oil well cement. It can be cross-linked with multivalent metal ions to form a gel.
4. This product is used for fracturing petroleum water-based gel fracturing fluid, polystyrene and polyvinyl chloride and other polymeric dispersants. It can also be used as a latex thickener in the paint industry, humidity-sensitive resistors in the electronics industry, cement inhibitors and moisture retention agents in the construction industry. Ceramic industry glaze and toothpaste adhesive. It is also widely used in printing and dyeing, textile, papermaking, medicine, hygiene, food, cigarettes, pesticides and fire extinguishing agents.
5. Used as surface active agent, colloidal protective agent, emulsion stabilizer for vinyl chloride, vinyl acetate and other emulsions, as well as latex thickener, dispersant, dispersion stabilizer, etc. It is widely used in coatings, fibers, dyeing, papermaking, cosmetics, medicine, pesticides, etc. It also has many uses in oil exploration and machinery industry.
6. Hydroxyethyl cellulose has surface activity, thickening, suspension, adhesion, emulsification, film formation, dispersion, water retention and protection in pharmaceutical solid and liquid preparations.
7. It is used as a polymer dispersant for petroleum water-based gel fracturing fluid, polyvinyl chloride and polystyrene. It can also be used as a latex thickener in the paint industry, a cement retarder and moisture retaining agent in the construction industry, a glazing agent and toothpaste adhesive in the ceramic industry. It is also widely used in industrial fields such as printing and dyeing, textile, papermaking, medicine, hygiene, food, cigarettes and pesticides.
