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 water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel,and protective colloid properties of surface activity and maintain moisture function properties ect.
Hydroxypropyl methylcellulose (HPMC) is widely applied for the production of liquid detergent.
HPMC can make washing liquid detergents more viscous and the effect of washing more stable. HPMC is one of the essential additives in clothes and dish detergent. In the solution, it functions as a thickening agent and protects other ingredients against sedimentation.
HPMC is a natural polymer cellulose made by a series of chemical treatments . It's a water-soluble white powder . It has thickened , adhesion , dispersion , emulsification , film formation , suspension , adsorption , gel and protective colloid surface activity , and retains moisture and other characteristics .
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
