Sell Hpmc

TF-E40000 Appearance: white or yellow flowing powder Particle sizes: 100% pass rate in 100 mesh Apparent density: 0.25-0.70 g/mL (usually about 0.5 g/mL),specific density 1.26-1.31mL. Color change: temperature:190-200°C;Carbonization temperature: 280-300°C Surface tension: 42-56 dyn / cm (2% aqueous solution) The higher methoxy content in HPMC, the lower gelation temperature, and the higher solubility in water and surface activity. HPMC has some other characteristics, for example, thickening property, pH stability, retention of water, excellent film-forming property, good disperse and adhesion ability.
