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.

Hydroxypropyl methylcellulose products can fully meet the standards for use of medicine, food, construction and personal care products.

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):HPMC also can use in detergent.


h) :Others:

- Used widely in the industry of leather, paper products, textile, fruits and vegetables fresh keeping, etc.
