Hydroxyethyl Cellulose (HEC)

Description:
Specifications:
1) Appearance: HEC is a white, yellowish-white or grayish-white powder or
granule, soluble in hot and cold water to form a colloidal solution and no
precipitate occurring under high or boiling point, practically insoluble in
acetone, alcohol and toluene. Its article size: 40 mesh screen (≥99%)
2) Softening temperature: 135 - 140°C; apparent density: 0.35 - 0.61g/ml;
decompose temperature: 205 - 21°C; moisture content equation size:
23°C; 50%rh - 6%, 84%rh - 29%
3) The viscosity of water solution is almost stable in pH2 - 12. But the viscosity of
the solution will reduce out of this pH range
4) HEC is a good colloid thickener for high concentration electrolyte solutions. The
solutions are stable even in the presence of other water-solubility polymers
and surfactants

Applications:
1) HEC is used for protecting colloid
2) HEC is used in the finished product for making the pigment and padding
additive homodisperse
3) HEC is used in styrene, methacrylate and acrylonitrile suspension
polymerization as dispersants
4) HEC is used as a component in water-based inks, water-based inks, textile
printings and dyes
5) It is also used in paper manufacturing and daily chemicals

Packing:
1) Kraft merchandise paper bag
2) Net weight: 25kg
