HPMC FEATURES
 
1.Stability
In the water-based paints, HPMC Hydroxypropyl Methyl Cellulose has excellent storage stability, maintains uniform viscosity, makes pigments uniformly dispersed, and basically won't be affected by the pH value.
 
2. Water-holding Property
In wall putty/ wall skim coat, the main roles of celluloses are water retention, adhesion, lubrication and so on. HPMC Hydroxypropyl Methyl Cellulose has high water-holding performance, surface opticity and improves uniformity. This helps to avoid crusting and off-powder phenomena, improve resistance to shrinkage, cracking and vertical flow, and to improve the work efficiency since the painting job is comfortable and saves effort.
 
3. Dispersibility
In the production of synthetic resin, HPMC Hydroxypropyl Methy lCellulose plays the role of protective colloidal agents and can effectively prevent polymeric particles from agglomerating.
 
4. Adhesion
In such materials as the adhesive mortar and surface mortar in the thermal mortar system, celluloses mainly plays a role of bonding, water retention and increasing strength. It also helps to improve construction, water-retaining property and resistance to hanging. 
 
5. Thickening Property
In interface agents, HPMC Hydroxypropyl MethylCellulose mainly functions as the thickening agent and can increase the the tensile strength and flexural strength.
 
6. Constructability
In the bonding of tiles, tile adhesives , HPMC can function as water-retaining agent and adhesives, and can greatly improve construction performance of adhesives, allow longer opening hours and greater cohesion, and prevent falling of tiles due to excessive water loss.

Name: Hydroxypropyl MethylCellulose(HPMC、MHPC)
Other Name: Cellulose hydroxy propyl methyl ether; Hypromellose, Cellulose, 2-hydroxypropyl Methyl ether. Cellulose hydroxypropyl methyl ether Hyprolose;
CAS Registry Number:[ 9004-65-3]

Hydroxypropyl Methyl Cellulose (HPMC) is non-ionic cellulose ether made from natural cotton fiber under series of chemical processing. It’s odorless, tasteless and non-toxic white powder, can be dissolved in cold water to form a transparent viscous solution with the properties of thickening, binding, dispersing, emulsifying, film coating, suspending, absorbing, gelling, water retention and colloid protection.


Physical Properties:
1. Appearance: HPMC is a nonionic cellulose ether, white grayish-white powder or granule,odorless and flavorless, soluble in cold water, glacial acetic acid, ethanol, methanol and propylene glycol, slightly soluble in acetone depending on the degree of substitutions, practically insoluble in hot water, ethylene glycol and toluene. HPMC is dissolved in a mixture of 10% methanol and 90% methylene chloride to form colloidal solutions.
2. The solution of HPMC has surface activity, high transparency, and stable performance. When heated at certain temperature, the solution becomes cloudy or forms flocculent gel. However, the solution becomes clear again after cooling. Different types of HPMC have different gelation temperatures. The solubility varies with the viscosity. The lower the viscosity, the higher solubility it has. The different types of HPMC are different in some properties and their solubility in water is not affected by pH.
3. Particle sizes:100% pass rate in 100 mesh.
4. Apparent density:0.25-0.70 g/mL (usually about 0.5 g/mL),specific density 1.26-1.31mL.
5. Color change temperature:190-200℃; Carbonization temperature:280-300℃.
6. Surface tension:42-56 dyn/cm (2% aqueous solution).
7. The higher methoxy content in HPMC, the lower gelation temperature, and the higher solubility in water and surface activity.
8. HPMC has some other characteristics, for example, thickening property, pH stability, retention of water, excellent film-forming property, good disperse and adhesion ability.
