HPMC(Hydroxypropyl methyl cellulose)
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.
Performance and application areas:
1. Strong plasticity: applied to gypsum without adding starch ether, bentonite, magnesium aluminum silicate, etc., improve mortar workability, adjust viscosity, apply effortless, non-stick knife, strong plasticity
2. The product has a high cost performance: low admixture, obvious effect, easy to construct;
3. Convenient construction: improve the batch scraping of gypsum, workers to save energy, feel smooth and coherent, non-sticky knife, improve the construction area of workers, improve construction efficiency.

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.
