Hydroxypropyl Meth`yl Cellulose

Abbr.: HPMCHPMC is white or similar to white fiber or granular powder, HPMC has two components: (1) cellulose (2) hydroxypropyl group (3) meth`oxy subgrade group. On each annulus fibrosis are three hydroxyls.It is widel used as thickener, adhesive, water preserving agent, 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.

Dissolving process HPMC will agglomerate when directly added to water and then dissolve. In this way it dissolves very slow and hard. Suggested meth`ods 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 70. 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 70 add HPMC by sequence of a). Make it disperse to form slurry state. 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 Application It is widel used as thickener, adhesive, water preserving agent, 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 Packing Net wt 15kg or 20kgs in cardboard drum with PE lining or coated PP woven bag, stored indoors in dry and draughty place avoid rain and sunlight during transporting.
