描述：

Hydroxypropyl  Methyl  Cellulose (HPMC) are non-ionic cellulose ethers , which are mad    e from natural macromolecular material cellulose through a series of chemical processes . H  yd roxy  propyl  methyl  cellulose (HPMC) are odorless , tasteless and nontoxic  white powder s, which can dissolve in cold water and form transparent viscous solution . They are  charact erized by thickening , adhesion , dispersion , emulsification , film formation , suspension , adsor ption , gel-ation , surface activity , water retention and colloid protection . Hydroxy  propyl  methyl  cellulose ether (HPMC) can be used in construction , building mater ials , coatings，synthetic resins , ceramics , medicine , food, textile , agriculture , cosmetics , toa cco and other industries .
