Is the higher the viscosity of polyacrylamide (PAM) the better?

Answer: The higher the viscosity of polyacrylamide (PAM), the better.

The higher the viscosity of polyacrylamide does not necessarily mean the better its performance. In general, the performance of polyacrylamide products with higher viscosity may be better, because high viscosity usually means higher molecular weight and longer polymer chain, so its flocculation effect may be better.

However, this is not an absolute rule, because the performance of polyacrylamide is affected by many factors, including molecular weight, ionicity, shear force, shape and size of polymer particles, etc. Therefore, the performance of polyacrylamide cannot be judged simply by its viscosity, but should be selected in combination with specific application requirements and experimental data.
