HPMC use: 1. Construction industry: As cement mortar water-absorbent and retarding agent, mortar has pumping capacity. Use mortar, plaster, putty powder or other building materials as adhesives to improve serviceability and prolong operation time. Paste ceramic tile, marble, plastic decoration, plaster enhancer, also can reduce the amount of cement.

The water retention performance of HPMC ensures that the slurry does not dry and crack too quickly, thereby increasing the strength after hardening.

2. Ceramic manufacturing: Widely used as adhesives in the manufacture of ceramic products. 3. Coating industry: As Thickener, dispersant and stabilizer in the coating industry, it has good solubility in water or organic solvents.

As a paint-stripping agent.

4. Ink printing: As an ink industry thickener, dispersant and stabilizer, in the water or organic solvents have good solubility.

5. Plastic: Molding release agent, softener, lubricant and so on.

6. Polyvinyl chloride: As a dispersant in the production of PVC, the main additive of PVC is prepared by suspension polymerization.

7. Other: The product is widely used in leather, paper products, fruit and vegetable preservation and textile industry.



8. Pharmaceutical industry: coating materials, membrane materials, controlled velocity polymer materials for sustained release formulations, stabilizers, suspension auxiliaries, tablet adhesives.
