Hydroxypropyl methylcellulose (INN name: Hypromellose), also simplified as hydroxypropyl methylcellulose (HPMC), is a variety of nonionic cellulose mixed ethers. It is a semi-synthetic, inactive, viscoelastic polymer .This product is industrial grade HPMC, mainly used as the dispersing agent for PVC production and as the main assistant used in producing PVC suspension polymerization.
It is also used as thickener, stabilizer, emulsifier, excipient, water retention agent, and film-forming agent etc.in producing petrochemicals, building materials, paint removers, agricultural chemicals, inks, textiles, ceramics, paper. cosmetics and other products.
HPMC are ethers of cellulose and propylene oxide. It is easily soluble in cold water but not soluble in hot water. It is non-ionic cellulose ether and is compatible with many surfactants and polymers such as starch, guar and alginates. Solutions of HPMC are pseudoplastic, some solutions show thixotropy.
Hydroxypropyl methylcellulose polymers are well-known for their ability to bind, retain water, thicken, form films, and provide many other performance benefits.
Hydroxypropyl methyl cellulose is divided into two kinds of ordinary hot soluble cold water instantly soluble. Hydroxypropyl methyl cellulose uses are 1, Gypsum series In the gypsum series of products, cellulose ethers are mainly used to retain water and increase smoothness. Together they play a cer
