The main application of hydroxypropyl methylcellulose

HPMC generally refers to hydroxypropyl methylcellulose, hydroxypropyl methylcellulose, and is also simplified as hypromellose, which is a variety of non-ionic cellulose mixed ethers.

It is a semi-synthetic, inactive, viscoelastic polymer that is often used as a lubricant in ophthalmology, or as an excipient or excipient in oral pharmaceuticals, and is commonly found in various commercial products.

1. Construction industry: As a water-retaining agent and retarder for cement mortar, it has good pumping performance. Mortar, stucco, putty powder and other construction materials are used as adhesives to improve its applicability and prolong its use time.

It is used for pasting tiles, marble, plastic decoration, and pasting steel bars, and can also reduce the amount of cement. The water retention performance of HPMC prevents the paste from cracking due to too fast drying after application, and the strength is improved after hardening.

2. Ceramic manufacturing industry: widely used in the bonding of ceramic products.

3. Coating industry: as a thickener, dispersant and stabilizer, soluble in water or organic solvents. Used 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.
