HPMC application
1. Building industry: as the water-retaining agent and retarding agent of cement mortar, the mortar has the pumping ability.Use mortar, gypsum, putty powder or other building materials as adhesives to improve the applicability and prolong the operation time.Use as paste ceramic tile, marble, plastic adornment, paste enhancement agent, still can reduce cement dosage. HPMC's water retention performance ensures that the slurry will not dry too fast and crack, enhancing the strength after hardening.
2. Ceramics 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 remover.
4. Ink printing: as thickener, dispersant and stabilizer in ink industry, it has good solubility in water or organic solvent.
5. Plastic: forming mould release agent, softener, lubricant, etc.
6. Polyvinyl chloride: as a dispersant in PVC production, the main additive of PVC is prepared by suspension polymerization.
7. Other: this product is widely used in leather, paper products, fruit and vegetable preservation and textile industry.
8. Pharmaceutical industry: coating materials;Membrane material;Controlled speed polymer materials for sustained-release preparations;Stabilizing agent;Suspended aid;Tablet adhesive.
