Hydroxypropyl methylcellulose (INN name: Hypromellose), also simplified as hydroxypropyl methylcellulose (HPMC), is a variety of nonionic cellulose mixed ethers.
HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural hIgh molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect.
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.
Application:
*thermal insulation mortar, ceramic tile adhesive, jointing agent, stucco gypsum, plaster;
*paint thickening agent, dispersing agent and stabilizer;
*ink industry as the thickening agent, dispersing agent and stabilizer;
*plastic forming mold release agent, softener, lubricants;
*cement, gypsum secondary products;
*shampoo, detergent
