According to the application needs of the product, there are usually very wide requirements for the viscosity and purity of HPMC. Under the same degree of substitution, the viscosity has a certain effect on the gel temperature: the lower the viscosity, the higher the gel temperature; the higher the viscosity, the lower the gel temperature.
