Factors Influencing HPMC Viscosity
February 10th 2025
Following are some of the key factors that may have an impact on HPMC viscosity:
1. Molecular weight: The higher the molecular weight, the higher the viscosity.
2. Degree of substitution: The number and type of substituent groups determine the polymer’s solubility and viscosity.
3. Concentration in solution: The higher the concentration, the thicker the solution.
4. Temperature: The viscosity of HPMC tends to be influenced by temperature and usually decreases at elevated temperatures.
