Physical and Chemical Properties

1. Product name:  

Industrial Chemicals Hydroxypropyl Methyl Cellulose

2. Appearance:  

Hydroxypropyl Methyl Cellulose HPMC is a white or whitish fibrillar/granular and odorless powder.

3. Dissolvability:   

Hydroxypropyl Methyl Cellulose HPMC is dissolvable in cold water and become clear or slightly  cloudy liquid cement,  but hardly in absolute ethyl alcohol, ethyl ether or propanone. In addition,  HPMC is dissolvable in some organic solvents or soce mixed solvents of water and organic solvent.

0.30-0.70g/cm3 and density: 1.26-1.31g/cm3

Product Features
1.   Salt Resistance:  
Hydroxypropyl Methyl Cellulose HPMC is a type of nonionic cellulose ether rather than poly electrolyte. Therefore, it is relatively stable in water where metal salt or  organic electrolyte exists.  However , excessive  amount of electrolyte will lead to gelatinization and sedimentation.

2.   Surface Activity:  
Hydroxypropyl Methyl Cellulose HPMC has suface activity, which enables to act as  colloidal  protective  agent, emulsifying agent and dispersant agent.

3.   Thermal Gelatinization:  
Hydroxypropyl Methyl Cellulose HPMC will turn to  opaque gel  and settle  when heated to certain temperature, but it will restore to the original solution when it is cooled  down  continually. The temperature leading to such gelatinization and sedimentation depends mainly on the types,  concentration and heating rate of HPMC water solution.

4.   PH Stability:
The viscosity of Hydroxypropyl Methyl Cellulose HPMC is hardly affected  by acid or  alkali, and  it is  relatively stable when ph value is in the rang of 3.10 to 11.0.

5.   Water Retention: 
Hydroxypropyl Methyl Cellulose HPMC is a type of high-efficiency  water retention  agent  that  is  widely used in the production of ceramics, construction materials and many other fields.

6.   Adhesivity:
Hydroxypropyl Methyl Cellulose HPMC, as a type of high-performance  binding agent,  is applicable  to  the  production of coloring pigments, tobacco products, ceramic products and papermaking
