HPMC is non-inoic cellulose ethers prodcued from natural high molecular cellulose through series of chemical changes. HPMC and HEMC is specialized in construction industry as an additive in all kinds of dry powder putty, dry mortar, tile adhesive, Water resistant putty,external wall insulation mortar, especially used for building putty and Mortar. So does painting,synthetic resin, porcelain,medicine, food, textile, agriculture, cosmetics and tobacco.
Cellulose ether HPMC is a non-ionic, water soluble white powder. It can be used as an agent of water retention, thickening, adhesive and dispersing, and also plays a role of protective colloid, stabilizer,suspension and film forming.
HPMC is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecular cellulose through series of chemical processing and achieved.It is white powder with good watersolubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel,and protective colloid properties of surface activity and maintain moisture function properties ect.
3. What are the dissolution methods of hydroxypropyl methylcellulose (HPMC)?——Answer: Hot water dissolution method: Since HPMC does not dissolve in hot water, HPMC can be uniformly dispersed in hot water at the initial stage, and then quickly dissolve during cooling. Two typical methods are describe
Industrial-grade hydroxypropyl methyl cellulose used in mortar is distinguished by viscosity. Generally, the following types are commonly used Low viscosity: 400 is mainly used for self-leveling mortar. Reason: low viscosity, good leveling, high mortar density. Medium and low viscosity: 20000-400000
