Cellulose Ether HPMC Construction Grade

Cellulose Ether HPMC Construction Grade 

High Viscosity Cellulose Ether Hpmc
china Building Material Cellulose HPMC
Hydroxy Propyl Methyl Cellulose  ( HPMC )  Construction Grade
CAS No.: 9004-65-3
Hydroxypropyl MethylCellulose are 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.
Product properties
1. Water Retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient hydration.
2. Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
3. Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
4. Slip Resistance: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.
