HPMC viscosity tables categorize the polymer based on its viscosity in aqueous solutions, often measured at a specific concentration (commonly 2% w/v) and temperature (typically 20°C). The table includes grades of HPMC, such as low, medium, and high viscosity, with corresponding viscosity values. These grades allow formulators to select the appropriate type of HPMC for their specific needs.

One of the key differences between HEC and HPMC lies in their viscosity profiles. HPMC tends to exhibit a broader range of viscosities compared to HEC, making it more adaptable for specific formulations. HPMC can be tailored for both low and high viscosity applications, whereas HEC typically presents limited viscosity range options. This distinction makes HPMC more suitable for products requiring specific rheological properties, such as controlled-release formulations in pharmaceuticals.
