Physicochemical properties
1.Granularity: The pass rate of 100 items was greater than 95.5%, and the rate of 80 was 100%.
2.Properties: This product is a white or white powder, odorless, tasteless, non-toxic.
3.Carbonation temperature: 280-300℃
4.Discoloration temperature: 190-200℃
5.Surface tension: 2% water solution is 42-56dyn/cm
6.Solution performance: Soluble in water and solvent, aqueous solution has surface activity. The degree of transparency is high, the performance is stable, the solubility changes with the viscosity, the lower the viscosity, the greater the solubility.
Application
Take about 0.3-0.5%of the needed hot water and agitate so that the added product will swell completely then add in the remained water, which can be hot or cold, agitate to the appropriate and the product can dissolve completely. Present application fields of HPMC, such as:
