3. Main application：
The product’s main application is as dispersing agent in producing polrvinyl chloride, the suspension polymerization preparation PVC main additives. In addition, as the thickener, stabilizer, emulsifier, excipients, water-retaining agent, film-former of area like Divide lacquer agent, petroleum, chemical industry, building materials, agricultural chemicals, textile printing, printing ink, making paper, cosmetics, ceramic and so on. In the application of synthetic resin, can make the product particles neat, loose, appropriate proportion and good processing performance, and thus, basically replaced the gelatin and Polyvinyl alcohol. Also, in the construction of the project construction process, it is mainly used to build walls, painted plaster, embedded in the crack in mechanical construction. Particularly in the construction, used for decorative ceramic tile, marble, plastic adornment, high strength of stickup, still can reduce the dosage of cement. Used as thickener in coating industry , can make coating light is exquisite, don’t take off powder, improve levelling performance and so on. Used to paint the plaster, adhesive, stabilizer and colloidal suspension, also used as tablets adhesive.
4. Considerations for Packaging, Storage and transportation
The packaging of HPMC use the Polyethylene plastic bags as the lining, outer packing use the textile bag or composite paper bag. 25kg net weight per bag. Product should be placed in a cool and dry place, defend damp.
