Product Description
Physical properties:
a) Out looking:HPMC is a
white or light gray pellet or fibril power with odorless.
b) Solubility: hardly dissolves in waterless ethanol, aether or
-acetone. Separate, expands, in hot water with temperature about
*0℃ to *0℃. swiftly dissolves when cool down. The solution is very
stable. Gelatin at high temperature. Good humectants with good
dispersibility, adhesive, thickener, emulsification, water keep
ability and film forming ability and oil resistance. The film
formed possesses good toughness, flexibility and transparent. It
can dissolve in some organic solvents or some water-organic
components. Can be mixed with other emulsification agent due to non
hydronium structure but easy salt out. Solution is stabilized at
PH***2.
c)Density:0.***0.*0g/cm3 with density about 1.3g/cm3
Dissolving Process.
MC 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.
MC 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℃. Add MC
gradually while slowly, stir. At the beginning, MC 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℃ add MC 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 MC with identical volume of other powder, disperses them
sufficiently then add water to the mixture result MC dissolves
without agglomeration.
3.Organic solvent wet.
Dispersed or wet with orgnic solvents such as ethanol, glycol or
oil, then add water can cause MC completely dissolves.
