Hydroxypropyl Methyl Cellulose HPMC is white or yellowish powder that isodorless,tasteless and non-toxic.It has high hygroscopicity and is soluble in water to form a thick liquid. It has good heat-stability, resistance to salt and film-forming property.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 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
