High Viscosity Cellulose Ether Hydroxypropyl Methyl Cellulose HPMC with Best vendor Price!
PHYSICAL AND CHEMICAL PROPERTIES:
1. Appearance: White or off-white fibrous or granular powder, odorless.
2. Particle Size: Pass rate of 100 mesh is greater than 98.5%, pass rate of 80 mesh is 100%.
3. Carbonization Temperature: 280-300°C.
4. Bulk Density: 0.25-0.70 g/cm³ (usually around 0.5 g/cm³), specific gravity 1.26-1.31.
5. Discoloration Temperature: 190-200°C.
6. Surface Tension: 2% aqueous solution has a surface tension of 42-56 dyn/cm.
7. Water Solubility: Soluble in water and some organic solvents, such as ethanol/water, propanol/water, dichloroethane, etc. The water solution has high transparency and stable performance. Different specifications of the product have different gelation temperatures, which is the thermal gelation property of HPMC. Solubility varies with viscosity, lower viscosity results in higher solubility. Different specifications of HPMC have certain differences in performance, and the dissolution of HPMC in water is not affected by pH value.
8. As the methoxy content decreases, the gelation point of HPMC increases, water solubility decreases, and surface activity decreases.
9. HPMC is calorie-free and metabolically inert, not involved in the body's metabolism.

Product characteristics
Characteristic of HPMC
Water Retention:
HPMC significantly improves water retention in cement-based products. This ensures proper hydration of cement, leading to better strength development and reduced risk of cracks due to premature drying.
Workability:
It enhances the workability of mortars, plasters, and other construction mixtures. This makes them easier to spread, reducing labor effort and improving application efficiency.
Consistency and Sag Resistance:
HPMC helps maintain the consistency of construction mixtures, preventing sagging and improving the stability of applied layers on vertical surfaces.
Improved Adhesion:
It enhances the adhesive properties of mortars and tile adhesives, ensuring better bonding between tiles, bricks, or other construction materials and the substrate.
Open Time:
HPMC extends the open time of mortars and adhesives, allowing for longer working periods and adjustments after application without compromising performance.
Rheology Modification:
It modifies the rheological properties of construction mixtures, providing the right balance between viscosity and flow. This ensures smooth application and finish.
Crack Resistance:
By improving water retention and workability, HPMC helps in reducing the formation of cracks in plaster and mortar due to shrinkage during drying.
Temperature Stability:
HPMC retains its performance characteristics over a wide temperature range, ensuring consistent results in different climatic conditions.
Compatibility:
It is compatible with a wide range of other construction additives and ingredients, allowing for versatile formulation options.
