Hydroxypropyl Methyl Celluloseare types of non-ionic cellulose ether, which are a powder of white to off white color, that function as a thickener, binder, film-former, surfactant, protective colloid, lubricant, emulsifier and suspension and water retention aid. In addition, there types of cellulose ethers exhibit properties of thermal gelation, metabolic inertness, enzyme resistance, low odor and taste, and PH stability.Due to the myriad of properties, HPMC is often used to substitute many other additives with lower concentration, making HPMC an incredibly efficient and effective additive in area of adhesives, construction, foods, household products, pharmaceuticals and etc.
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.
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
Hydroxypropyl methyl cellulose ether-HPMC, as an auxiliary additive widely used in the field of building materials, is mainly used for water retention, thickening and improving the workability of the finish product. Water retention rate is often one of the core indicators for selecting high-quality
