Physical properties:
1) Appearance: HPMC is a white or light gray pellet or fibril power with 
    odorless and tasteless
2) Solubility: hardly dissolves in waterless ethanol, aether or acetone, 
    expands as to clear or slightly muddy colloid solution in cold water; it 
    can dissolve in some organic solvents or some water-organic components
3) Pellet: 100 screen passable rate is over 98.5%, 80 screen passable rate
    is 100% 

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: add water in container to 1/3 or 2/3 of its content, heated
    to over 80°C, because HPMC doesn't dissolve in hot water, it uniformly 
    disperses in hot water; add cool water or ice to the residual 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 mixture result HPMC 
    dissolves without agglomeration
3) Organic solvent wet: dispersed or wet with organic solvents, such as 
    ethanol, glycol or oil, then add water can cause HPMC completely dissolves

Applications:
HPMC is mainly used as dispersant in the production of PVC and as thickener, stabilizer, emulsifier, excipient, water retention agent, film-forming agent in petrochemical, building materials, agrochemical, ink, printing and dyeing of textile,
paper making and cosmetics. 

Transportation and storage:
1) Keep dry where good ventilated
2) Do not wet and keep away from sunshine during transportation

Packing:
25kg/multi-paper bag or kraft paper bag
