Hydroxyethyl cellulose(HEC)

Hydroxyethyl cellulose(HEC)backed by the top technical forces and complete testing methods from.

Hydroxyethyl Cellulose(HEC) is non-ionic water-soluble polymer; it is effective in thickening, bonding, emulsifying, dispersing, stabilizing and water preserving in such industries like architectural coating, petroleum and daily-use chemicals. Hydroxyethyl cellulose is very easily soluble not only in cold water, but also in hot water, and can provide solutions with wider range of viscosity.

 

Properties

Hydroxyethyl Cellulose is made from natural polymer cellulose, it is white to yellowish, odorless and tasteless powdered solid.

Structural Formula

n=degree of polymerization, R=-H or (CH2-CH2-O)xH

 

Technical Specifications(Table 1)

Item	Details
Appearance	yellowish or white odorless and tasteless granular powder.
Molar substitution degree	1.8-3.0
Viscosity	See Table 2
