Performance and use of Hydroxy Ethyl Cellulose (HEC) ⑴

Hydroxyethyl cellulose HEC is a white or slightly color odorless, tasteless and easy-flowing powder, 40 mesh sieving ≥99%; softening temperature: 135℃—140℃; apparent density: 0.35—0.61g/cm3, decomposition temperature: 205 ℃-210℃; slower burning speed; equilibrium moisture content: 23℃; 6% at 50%rh, 29% at 84%rh.

It is soluble in cold water and hot water, and is generally insoluble in solvents in most agricultural production systems. The viscosity change is small in the PH value range of 2-12, but the viscosity decreases beyond this range. The surface-treated HEC generally starts to appear viscosity in about 40 minutes. If the PH value is adjusted to 8-10, it can be dissolved quickly.
