The Importance of Viscosity


HPMC viscosity grades range from low to high, with lower viscosity grades typically having smaller molecular weights and lower degrees of substitution.

In contrast, higher viscosity grades have larger molecular weights and higher degrees of substitution, making them more suitable for applications that require thicker films, increased water retention, or longer-lasting effects.
