Product Description
1. Product Introduction
HEC is produced from cellulose, which reacts with sodium hydroxide to form basic cellulose colloid. And then the ethylene oxide and other chemicals are added into the reaction to get etherification. By controlling the production parameters, the Hydroxyethyl cellulose is produced.
HEC is a white or light yellow powder, non-toxic, tasteless, can be quickly dissolved into hot or cool water, insoluble in general organic solvent, with excellent character of thickening, dispersing, emulsifying, adhesion, stabilizing, water retention and film forming. Also can be used as a protective colloid in some products. It can be widely used in oil drilling, coatings, food, textile, building and macromolecule polymerization, etc.
