Hydroxypropyl Methyl Cellulose
Brief Introduction:
Hydroxypropyl methylcellulose, also known as hypromellose, is a kind of nonionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer that is often used as a lubricant in ophthalmology, or as an adjuvant or excipient in oral pharmaceuticals.

Applications:
1. Construction Industry:
As a water-retaining agent and retarder of cement mortar, it makes the mortar pumpable. In plaster, gypsum, putty powder or other building materials as a binder to improve spreadability and prolong work time. It can be used as paste tile, marble, plastic decoration, paste reinforcement, and can also reduce the amount of cement. The water-retaining performance of HPMC prevents the slurry from cracking due to drying too quickly after application, and enhances the strength after hardening.
2. Ceramic Manufacturing Industry:
It is widely used as a binder in the manufacture of ceramic products.
3. Coating Industry:
It is used as a thickener, dispersant and stabilizer in the coating industry, and has good compatibility in water or organic solvents. As a paint remover.
4. Ink Printing:
It is used as a thickener, dispersant and stabilizer in the ink industry, and has good compatibility in water or organic solvents.
5. Plastic:
Used as forming 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 preparing PVC by suspension polymerization.
7. Pharmaceutical Industry:
Coating materials; film materials; rate-controlling polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet binders; viscosity-increasing agents.
8. Others:
It is also widely used in leather, paper products, fruit and vegetable preservation and textile industries.
Packaging:
25kg net weight paper-plastic composite bag lined with PE bag; 500kg packed on one pallet.
Storage & Transportation:
