Hydroxypropyl MethylCellulose (HPMC) are widely used in construction, pharmaceutical,food, cosmetic, detergent, paints, as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids.
HPMC-Hydroxypropyl Methyl Cellulose and Methyl Hydroxyethyl Cellulose and non-ionic cellulose ether made by natural high polymer cellulose as raw material and series of chemical processing. They are odorless, tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution. Processing thickening, binding, dispersing, emulsifying, film, coating, suspending, absorbing, gelling, surface activity, water maintaining and protective colloid properties
Hydroxypropyl methyl cellulose HPMC is a non-ionic water-soluble cellulose mixed ether. The appearance is white to light yellow powder or granules, tasteless, odorless, non-toxic, it is a chemically stable product, soluble in water, forming a smooth and transparent viscous solution. The production process of HPMC is mainly to form polysaccharide ether products after etherification of cotton fibers. It has no charge itself, does not react with charged ions in cementitious materials, and has stable performance. cheap price. Widely used in dry powder mortar. In mortar, the thickening of the mortar can have a certain wet viscosity, which helps to maintain the amount of free water in the mortar, so that the gel material has more time to hydrate after the mortar is used.
