Characteristics of HEC
Hydroxyethyl cellulose (HEC) is a white or light yellow, odorless, non-toxic fibrous or powdered solid. It is prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chloroethanol), and belongs to non-ionic soluble cellulose ethers. Due to its good thickening, suspension, dispersion, emulsification, adhesion, film formation, moisture protection and protective colloid properties, HEC has been widely used in oil extraction, coatings, construction, medicine and food, textiles, papermaking and polymer polymerization. 40 mesh sieving rate ≥99%.
