hpmc,hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose
HPMC is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder.HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.
HPMC has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and a wide range of enzyme resistance, dispersion and adhesion.
hpmc,hydroxypropyl methylcellulose 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.
