Hydroxypropyl methylcellulose (HPMC) 羟丙基甲基纤维素（HPMC）

    Hydroxypropyl methylcellulose is white or off-white powder. It is mainly used as a dispersant in the production of polyvinyl chloride. In addition, it is used as a thickener, stabilizer, emulsifier, and film-forming agent in the production of other petrochemicals, coatings, building materials, paint removers, papermaking, cosmetics and other products.

1. Construction industry: As a water-retaining agent and retarder for cement mortar, it makes the mortar pumpable. Used as a binder in plastering paste, gypsum, putty powder or other building materials to improve spreadability and prolong operation time. It is used as a paste for ceramic tile, marble, plastic decoration, as a paste enhancer, and it can also reduce the amount of cement. The water retention of HPMC can prevent the slurry from cracking due to drying too fast after application, and enhance the strength after hardening.

2. Ceramic manufacturing: widely used as a binder in the manufacture of ceramic products.

3. Coating industry: As a thickener, dispersant and stabilizer in the coating industry, it has good compatibility in water or organic solvents. as a paint remover.

4. Ink printing: as a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvents.

5. Plastic: used as molding release agent, softener, lubricant, etc.

6. Polyvinyl chloride: It is used as a dispersant in the production of polyvinyl chloride, and it is the main auxiliary agent for the preparation of PVC by suspension polymerization.

7. Pharmaceutical industry: coating materials; film materials; rate-controlling polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet binders; tackifiers

8. Others: It is also widely used in leather, paper product industry, fruit and vegetable preservation and textile industry.
