A brief introduction to hydroxyethyl cellulose


Hydroxyethyl cellulose (HEC), chemical formula (C2H6O2)n, is a white or light yellow, odorless, non-toxic fibrous or powdery solid composed of alkaline cellulose and ethylene oxide (or chlorohydrin) It is prepared by etherification and belongs to non-ionic soluble cellulose ethers. Because HEC has good properties such as thickening, suspending, dispersing, emulsifying, bonding, film-forming, protecting moisture and providing protective colloids, it has been widely used in oil exploration, coatings, construction, medicine and food, textiles, papermaking and polymers. Polymerization and other fields. 40 mesh sieving rate ≥ 99%.
