Hydroxypropyl MethylCellulose (HPMC) is a non-ionic cellulose ether made from natural high-polymer cellulose through a series of chemical processes. It is an odorless, tasteless, and non-toxic white powder that dissolves in cold water to form a transparent viscous solution.
In the construction industry, it acts as a high-performance additive providing essential properties such as thickening, binding, dispersing, emulsifying, film-forming, and superior water retention. It significantly improves surface activity and protective colloid properties in various building materials.
