Product Description

HPMC/hydroxy propyl methyl cellulose

1. Appearance: white or almost white powder.
2. Granularity: pass rate of 100 mesh is greater than 98.5%; pass rate of 80 mesh is greater than 100%.
3. Carbonization temperature: 280-300°C
4. Apparent density: 0.25-0.70g cm3 /(usually 0.5g/cm3 or also), and the proportion is 1.26-1.31.
5. Color change temperature: 190-200°C
6. Surface tension: the surface tension of 20% aqueous solution is 42-56dyn/cm at 25°C.
7. Solubility: Soluble in water and some solvents, such as an appropriate proportion of ethanol/water, propanol/water, dichloroethane etc. Aqueous solution is of surface activity with high transparency and stable performance. The gel temperature of products with different specifications is different. Solubility varies with the viscosity; the lower the viscosity, the greater the solubility. There are some differences between HPMC with different specifications. The dissolution of HPMC in water will not be affected by pH value.
