HEC cellulose, derived from natural cellulose through chemical modification, boasts a unique blend of versatility and functionality that makes it an indispensable material in today's world.
- The relationship between HEC viscosity and concentration is not linear and follows a specific pattern. At low concentrations, the viscosity of HEC solutions is relatively low as the polymer chains are not interacting with each other. However, as the concentration of HEC increases, the polymer chains start to entangle and interact, leading to an increase in viscosity. This increase in viscosity continues until a critical concentration is reached, beyond which the viscosity levels off or even decreases due to the formation of a gel network
