We are one of the leading manufacturer of Hydroxypropyl methyl
cellulose (HPMC)
Properties:
1. Appearance: HPMC is white or similar to white fiber or granular
powder; Odorless.
2. Properties: Almost insoluble in ethanol, ether and acetone;
Quickly dispersed in ****0 centigrade water; Aqueous solution is
very stable in room temperature; Has good
wetting/dispersing/adheisve/thickening/emlusifying/water
preserving/film-forming properties; Can prevent the infilration of
grease; Film formed has excellent flexibility and trransparency;
Has good compatibility with other emulsifier; Easy salting-out. Its
solution is stable with pH ***2.
3. Apparent density: 0.***0.*0g/cm3, density is 1.3G/cm3.
Dissolving process
HPMC will agglomerate when directly added to water and then
dissolve. In this way it dissolves very slow and hard. Suggested
methods as followers:
1. In hot water.
HPMC does not dissolve in hot water. The primary HPMC can be
uniformly disperse in hot water. Then cool down in two ways:
A) Add hot water in container and heated to over *0 centigrade. Add
HPMC gradually while slowly, stir. At the beginning, HPMC float on
the top of water, then turns into slurry state stir and cool
down.
B) Add water in container to 1/3 or 2/3 of its content. Heated to
over *0 centigrade add HPMC by sequence of a). Make it disperse to
form slurry state. Add cool water or ice to the resideual content,
stir and cool down the mixture.
2. Powder combination.
Mix HPMC with identical volume of other powder, disperses them
sufficiently then add water to the
Application

film-forming agent in construction, building materials, dispersion
coating, wallpaper paste, polymerization aids, leathers, printing
ink and paper making etc. L also used in petroleum drilling and
daily-use chemicals
