Hydroxypropyl methyl cellulose

Hydroxypropylmethylcellulose (Hypromellose), also known as hydroxypropylmethylcellulose, is one of the mixed ethers of nonionic cellulose.It is a semi-synthetic, inactive, viscoelastic polymer, often used as a lubricant in ophthalmology, or as an excipient or excipient in oral drugs.

Synonyms: (Hydroxypropyl)methyl cellulos

Molecular formula: C3H7O

CAS No: 9004-65-3

UN NO: N/A

Application:

Construction industry

1. Cement mortar: improve the dispersion of cement and sand, greatly improve the plasticity and water retention of the mortar, and have an effect on preventing cracks and enhancing the strength of the cement.

2. Ceramic tile cement: improve the plasticity and water retention of pressed ceramic tile mortar, improve the adhesion of ceramic tiles, and prevent pulverization.

3. Coating of refractory materials such as asbestos: As a suspension stabilizer and fluidity improver, it also improves the adhesion to the substrate.

4. Gypsum coagulation slurry: improve water retention and processability, and improve adhesion to the substrate.

5. Joint cement: Added to the joint cement used in gypsum board to improve fluidity and water retention.

6. Latex putty: Improve the fluidity and water retention of resin latex-based putty.

7.Stucco: As a paste instead of natural materials, it can improve water retention and improve adhesion to the substrate.

8. Coatings: As a plasticizer for latex coatings, it has an effect on improving the operating performance and fluidity of coatings and putty powders.

9. Spraying coating: It has a good effect on preventing the sinking of the cement-based or latex-based spraying material filler and improving the fluidity and spray beam pattern.


Ceramic manufacturing industry:

It is widely used as a binder in the manufacture of ceramic products.


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.


Ink printing:

As a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvents.


Pharmaceutical industry:

coating materials; film materials; speed-controlled polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet adhesives; thickeners.


Other industries

1. Fiber: As a printing and dyeing paste, it is used for pigments, borotulin dyes, salt-based dyes, and textile dyes. In addition, it can be used in combination with thermosetting resins in the corrugated processing of kapok.

2. Paper: Used for gluing the leather surface of carbon paper and oil-resistant processing, etc.

3. Leather: used as a final lubricant or disposable adhesive

4. Water-based ink: added to water-based ink and ink, as a thickener and film-forming agent.

5. Tobacco: As a binder for regenerated tobacco.
