High Viscosity 200,000 cps HPMC
High Viscosity 200,000 cps HPMC
Hydroxypropyl Methylcellulose (HPMC) with a high viscosity of 200,000 cps (centipoises) is a cellulose ether widely used in construction, pharmaceuticals, and other industrial applications. Its high viscosity gives it excellent thickening, film-forming, and water retention properties, making it ideal for various applications.
Key Properties
- Thickening Power: Provides high viscosity even in low concentrations, suitable for formulations requiring a stable and thick texture.
- Water Retention: Retains moisture effectively, critical in construction materials like cement and gypsum-based plasters.
- Solubility: Easily dissolves in cold water, forming a clear or slightly turbid solution.
- Stability: Stable across a wide pH range (3-11) and resistant to enzymatic degradation, ensuring long-lasting performance.
- Thermal Gelation: Forms gels upon heating, which revert to solutions on cooling, a desirable property in some pharmaceutical and food applications.
Applications
1. Construction Materials
- Tile Adhesives: Enhances adhesion, workability, and water retention, ensuring proper curing of tiles.
- Mortars and Plasters: Improves spreadability, anti-sagging properties, and water retention for consistent application.
- Self-Leveling Compounds: Ensures smooth leveling and prevents cracking by retaining moisture.
2. Pharmaceuticals
- Excipient in Tablets: Acts as a binder and film-former in controlled-release formulations.
- Eye Drops: Used as a viscosity enhancer for longer retention on the eye surface.
3. Personal Care Products
- Used in shampoos, creams, and lotions to provide desired consistency and improve stability.
Advantages of High Viscosity HPMC
- Reduces water usage in formulations by maintaining moisture for extended periods.
- Improves the durability and performance of construction materials.
- Ensures consistency and stability in pharmaceutical and personal care products.
Usage Tips
- Dissolve in cold water with gentle stirring to prevent lump formation.
- Adjust concentration according to application requirements; higher concentrations yield thicker textures.
If you have specific requirements for your application, custom grades and modifications of HPMC are often available.
