DESCRIPTION
Povidone K90
The aqueous solution of pvpk90 is non thixotropic in most cases and has a short relaxation time. When the concentration is very high, it will have a certain structural viscosity; when the shear force is increased, the viscosity will decrease. Controlling the concentration of pvpk90 will bring many different application performances to pvpk90.
