Hydroxypropyl Methyl Cellulose (HPMC) Properties That Enables Its Wide Applications

Hydroxypropyl methyl cellulose (HPMC) is natural cellulose and raw material obtained after several chemical processes. HPMC, a non-ionic roughage ether, is a colorless powder that dissolves in water readily.

 

HPMC properties include adhesion, thickening, emulsifying, dispersing, suspended, film, gel, shielding colloid possessions of simple action, adsorption, and ability to uphold moisture utility.

 

HPMC properties


Due to its exceptional properties, hydroxypropyl methyl cellulose applications are widespread in building materials, construction, coating industry, ceramic, agriculture, and textiles, home care, pharmaceutical, among others, uses.

 

However, when buying HPMC for your project, you should partner with a reliable and reputable manufacturer for original and quality raw materials.

 

Other Notable HPMC Properties

· It has an adequate particle size that about 98.5% to 100% can be sieved using 100 to 80mm mesh size.

· It chars at a temperature range of 280-300℃.

· It possesses a density of about 0.5 g/cm3

· HPMC is soluble in an organic solvent; examples include ethanol, methylene chloride, propyl alcohol, etc.

· It has a wide range of pH value of 5.0~ 7.5 and a moisture value of ≤ 5.0

 

Hydroxypropyl Methyl Cellulose (HPMC) Application based on Properties

1. Adhesive

HPMC is an excellent retainer of water that extends the opening time, thereby making tiling more effective. It enhances adhesion and resists slipping, particularly for tiles with weight.

 

HPMC gives the better working condition that is lubricity and flexibility of plastic is certain. It allows the easy and quick application of mortar.

 

2. Mortar Based Surface

HPMC allows easy formulation mixture drying because it dissolves in cold water. Therefore, any formation of a lump can be escaped. This is a plus when applying heavy tiles.


It retains water, and this helps in averting any loss of substrates. This is achieved by keeping an appropriate water quantity in the mixture that assures extended setting time.


It increases water demand by extending opening time, stretched active area giving rise to cost-effective preparation. It spread quickly and enhanced sagging resistance because of better-quality stability.

HPMC properties

3. Exterior Wall Temperature Insulation System

HPMC has the ability to insulate external heat that may arise, thereby enriching adhesion. It wets the substrates and EPS board better. It abridged air bubbles and water incorporation.


4. Self-leveling

It protects against any water oozing out and sedimentation of materials. HPMC properties guide against slurry volatility, while its water-retaining properties enhance the quality performance on the exterior.

 

5. Crash Plaster

HPMC provides a better working condition, which enables good plasticity and thickness. Water retaining ability help in prolonging the time of working. Its sagging resistance improves the bonding ability of mortar.

 

6. Gypsum based Plaster

HPMC maximizes water quantity in slurry guarantees total gypsum concretes. Its function as an anti-sagging agent. This helps to avoid thicker coat lines. HPMC increases mortar outcome, subject to the weight of the dry formulation.

 

7. Ceramic  shape 

HPMC provides a better working condition for ceramic casting as a result of plasticity and lubricity. It ensures texture compaction and provides a smooth surface.
