Understanding these properties is crucial for manufacturers and developers aiming to leverage HPMC's full potential in their products.
An aqueous solution of HEC is a non-Newtonian fluid, and its viscosity changes as the shear rate changes.
The viscosity increases as the shear rate decreases, while the viscosity decreases as the shear rate increases (thixotropy).
The thixotropy of an aqueous solution of HEC increases with higher viscosity products with higher molecular weight, and decreases with lower viscosity products. Low-viscosity products have very low thixotropy and exhibit characteristics similar to Newtonian fluids.
