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.

(Hydroxypropyl)methyl cellulose is a thickener for aqueous and non-aqueous systems, clear films with grease resistance, binders,lubricants, steric stabilizer and water retention aid. Dissolves in water, undergoes reversible gelation upon heating, non-ionic, doesnot complex with ionic species and is surface actuce and enzyme resistant. Solutions are pseudoplastic.

In building materials, hydroxypropyl methyl cellulose can act as dispersing agents, thickeners and binders, and hydroxypropyl methyl cellulose is mainly used in the molding of the cement mortar and plaster products. It is used in the cement mortar to increase its adhesion, reduce flocculation, improve the viscosity, shrinkage, and water retention, reduce the water loss of concrete surface, enhance the strength, prevent the occurrence of cracks and weathering effects of water-soluble salts.
