Product Description
Hydroxypropyl Methyl Cellulose HPMC
Other name: Hypromellose
Hydroxypropyl methyl cellulose is a white powder. The pass rate of 100 mesh is greater than 98.5 %. The carbonization temperature is 280-300 °C. The color change temperature is 190-200 °C. Soluble in water and some solvents. The aqueous solution has surface activity, high transparency and stable performance. The lower the viscosity, the greater the solubility.
1. Take the required amount of water, heating to 85 °C or more. HPMC was gradually added under slow stirring. Cellulose initially floated on the water surface, but gradually dispersed to form a uniform slurry. Then the solution is cooled under stirring.
2. The 1/3 or 2/3 water was heated to above 85 °C, and cellulose was added to obtain hot water slurry. Then add the remaining amount of cold water, keep stirring and cool.
