Hydroxypropyl methylcellulose is a semi-synthetic, inactive, viscoelastic polymer commonly used in ophthalmology as a lubricant or as an excipient or excipient in oral medications and is commonly found in a variety of commercial products middle.

Influence:
Hydroxypropyl methylcellulose is used in the textile industry as a thickener, dispersant, binder, excipient, oil-resistant coating, filler, emulsifier and stabilizer. It is also widely used in synthetic resin, petrochemical, ceramic, paper, leather, pharmaceutical, food and cosmetics industries.

main meaning

Construction industry: As a water retaining agent and retardant for cement mortar, making the mortar pumpable. Used as a binder in plaster, plaster, putty or other building materials to improve spreadability and extend working time. It is used as a paste for ceramic tiles, marble, and plastic decoration. As a paste enhancer, it can also reduce the amount of cement. The water retention of HPMC can prevent the slurry from cracking due to too fast drying after construction and enhance the strength after hardening.

2. Ceramic manufacturing: widely used as a binder in the manufacturing 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 stripper.

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 release agent, softener, lubricant, etc.

6. Polyvinyl chloride: used as a dispersant in the production of polyvinyl chloride and the main additive for the preparation of PVC by suspension polymerization.

7. Others: This product is also widely used in leather, paper products, fruit and vegetable preservation, textile and other industries.

8. Pharmaceutical industry: coating materials; film materials; rate-controlling polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet adhesives; thickeners.
