Product Overview
HYDROXY PROPYL METHYL CELLULOSE HPMC E50 LV PREMIUM is a high-performance, water-soluble cellulose ether designed for precise viscosity control in laboratory applications. This low-viscosity grade offers exceptional clarity and film-forming properties, making it ideal for formulations where consistency and stability are critical. The premium-grade HPMC ensures minimal impurities, providing reliable performance in sensitive experiments. Its non-ionic nature makes it compatible with a wide range of solvents and additives, while its thermal gelation properties allow for controlled thickening at elevated temperatures. The powder form dissolves easily in cold water, forming smooth, uniform solutions without clumping. This grade is particularly valued for its ability to maintain viscosity over extended periods, reducing the need for frequent adjustments in experimental setups. The E50 LV variant is optimized for applications requiring moderate thickening with excellent flow characteristics, balancing ease of handling with functional performance.
FAQs
1. What is the solubility profile of HPMC E50 LV in different solvents?
HPMC E50 LV is fully soluble in cold water but insoluble in hot water above its gelation temperature. It shows limited solubility in ethanol and other organic solvents, with better dispersion achieved in water-alcohol mixtures.
2. How does the viscosity of HPMC E50 LV compare to other HPMC grades?
This grade has a lower viscosity range (40-60 mPa·s) compared to medium or high-viscosity HPMC variants, making it suitable for applications requiring moderate thickening without excessive gel formation.
3. What storage conditions are recommended to maintain product stability?
Store in a cool, dry place below 30°C in tightly sealed containers to prevent moisture absorption, which can lead to premature dissolution or clumping.
4. Are there any known incompatibilities with common lab reagents?
HPMC E50 LV may precipitate in solutions with high salt concentrations or strong electrolytes. It’s generally incompatible with cationic surfactants and some metal salts.
5. What particle size range can be expected with this HPMC grade?
The powder typically has a particle size distribution between 40-100 mesh, providing a balance between dissolution rate and dusting characteristics.
