Hydroxyethyl Cellulose
Product description:
Hydroxyethyl Cellulose (HEC) is nonionic cellulose ether derived
from natural fibre.It is widely used
Pharm.Cosmetic,Paint&coating,oilfield, construction,etc.,
having functions of thickening, bonding, stabilizing, water
retaining, film forming, and protective colloids,etc. HEC is
soluble in either hot or cold water,have broad range viscosity
designed for customer different needs.
Properties
*Excellent thickening agent
*Unique Pseudoplasticity:Reversible high viscosity in standstill
and thin out under shear
*Salt tolerance,stable and resistance in high concentration of
salts
*Film forming agent,protective colloid action.
*Water retention,maintain water content at formulation

Product Application:
*Paint&Coating
HEC is excellent thickener in polymer latexes,Paint&coatings.
It also has the functions of emulsifying, dispersing, stabilizing
and water-retaining besides thickening in latex paints. It is
characterized by obvious thickening effect, good properties of
color-extending, film-forming and stabilizing in storage. The
solution of HEC, as a nonionic cellulose derivative, can be used
within a wide pH range, and compatible with other compositions,
such as pigments, aids, fillers and salts, etc. The paints
thickened with HEC, having good rheological propertied under
different shear-rates and psudoplasticity, can be used by some
application methods of brushing, rolling, and spraying coating,
etc. The paints have good application and leveling properties
without dropping, sagging and spattering.
*Oilfield drilling,workover and completion
Our High-viscosity HEC is mainly used as viscosifier for completion
fluid and workover fluid in oilfield, and low-viscosity HEC as
water-loss control agent. In the different mud required for well
drilling, completing, cementing and fracturing operation, HEC, as a
viscosifier, impart mud good flowability and stability. It can
increase the muds carrying ability in well drilling and extend the
borers service life. In the low solid completing and cementing
fluids, the excellent water-loss controlling property of HEC will
prevent large amount of water from mud into oil reservoirs to
improve production ability from oil reservoirs.
*Polymerization
In the polymer and copolymer compositions of the synthetic resins,
HEC has actions of dispersing, emulsifying, suspending and
stabilizing, and is often used as protective colloid. It has
characteristics of strong dispersing ability, thinnermembraneof the
product granules which are fine, uniform and porous, good
flowability, high product transparency, and easy processing. Since
HEC is readily soluble in hot or cold water and has nocloudpoint,
it is suitable for different polymerization reactions. The
dispersing agents also have some important physical natures like
surface tension, interfacial strength, and gelling temperature and
these natures of HEC are suitable for polymerization and
copolymerization of synthetic resins.
HEC has good compatibility with other cellulose ethers and PVA,
etc. and the compound system from them can be attained to better
resultant effects. So the compound resin product has not only good
quality but also less material loss.
*Detergents and Cosmetics
HEC is an effective film-former, binder, thickener, stabilizer and
dispersing agent in shampoo, hair spraying agent, neutralizer, hair
conditioner and cosmetics. In the washing powder it is a dirt
redeposit agent. HEC can be dissolved into water quickly under high
temperature to speed up the production process and raise the
production efficiency. The detergents containing HEC has
distinguishing characteristics of improving flatness and silkiness
of textile.
*Building /Construction material
HEC can be used in building products, such as concrete mixes, newly
mixed mortar, gypsum, plaster, or other cements, etc. for its
water-retaining action. It can also be used in plaster or other
cement to prolong their curing and opening time, reduce skinning,
slipping and sagging, for improving application property, increase
production rate, saving time, and increasing plasters volume so as
to save the raw materials.
*Agricultural Products
HEC can be used in agrochemicals emulsion and suspension
formulations as thickener for reducing the chemicals running away
and it adhering to the plant leaf surface hard to raise the
application effect of spraying leaf surface.
HEC is also useful in seed coatings and tobacco recovery as
film-former and binder.
*Paper and Printing Ink
HEC can be used for surface sizing on paper and paper board and
water-based printing ink as thickener and suspending agent.
During the process of paper-making, HEC has excellent properties
including compatibility with most gums, resins and inorganic salts,
low foam, less oxygen consumption, and forming smooth surface film.
It will impart the film lower surface permeability and improved
gloss, and reduce in price. The paper sized with HEC can be used
for printing high quality picture.
In manufacturing water-based printing ink, the ink thickened with
HEC is characterized by drying quickly, good color dispersion and
no sticking.
*Textile
HEC can be used as binder and sizing agent in textile dye printing
paste and latex paint, thickener in rug back sizing material,
shape-forming agent and adhesive in glass fiber, finishing agent
and binder in leather paste. It provides wide range of viscosity
for these coatings and adhesives to stick the coating film
uniformly and quickly, and can improve definition for printing and
dyeing.
*Ceramics
HEC can be used for preparing high strength binder for
ceramics.
*Toothpaste
HEC can be used in manufacture of toothpaste as thickener,bonding
agent.
