Hydroxypropyl Methylcellulose

Hydroxypropyl methylcellulose (hpmc) is widely used in building materials, coatings, synthetic resins, ceramics, medicine, food, textiles, agriculture, cosmetics, and other industries.methyl cellulose is a non - ionic cellulose ether produced by a series of chemical processes.hydroxypropyl methyl cellulose is a kind of white powder that is odorless, tasteless and non-toxic, which can dissolve in cold water and form a transparent viscous solution.it is characterized by thickening, adhesion, dispersion, emulsification, film forming, suspension, adsorption, gelation, surface activity, moisture retention and protective colloid. Redispersible emulsion powder is mainly applied for the dry mixed mortar of the construction industry, and is the important additive of dry mixed mortar.
