Brif introduction
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials.
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.

Application
a) Construction
- Used as the water retaining agent and retarder in mortar to make it has good pumpability.
- Used as adhesives in plaster, gypsum material, putty powder or other construction materials to improve its workability and extend the operation time.
- Used as paste enhancer of ceramic tile, marble and plastic decoration and reduce usage of cement.
- HPMC water retention property can prohibit too fast dry and cracking after the slurry spraying and enhanced strength after hardening.
b) Ceramic industry
- Used widely as binder in the ceramic production industry.
c) Coating industry
- Used as thickening agent, dispersing agent and stabilizer in the coating industry.
- Have a good compatibility in water or organic solvents.
- Used as the paint remover/stripper.
d) Ink printing
- Used as thickening agent, dispersing agent and stabilizer in the printing ink industry.
- Have a good compatibility in water or organic solvents.
e) Plastic
- Used as forming release agent, softening agent, lubricant.
f) Polyvinyl Chloride (PVC)
- Used as dispersing agent in polyvinyl chloride production and is the main auxiliary for the suspension polymerization of PVC
g) Others:
- Used widely in the industry of leather, paper products, textile, fruits and vegetables fresh keeping, etc.
