Explaining Viscosity In Layman’s Terms

I just received this blog request…

I just read your past blog on crystallinity, could you briefly provide a layman’s description of viscosity?

My Response
Basically, viscosity is a measure of a polymer’s resistance to flow. The higher the viscosity, the higher the polymer’s resistance to flow.
For example: Honey has a higher resistance to flow than water does. As a result, we would say honey is more viscous than water.
Additional Thoughts
A good understanding of the fundamentals, such as crystallinity, viscosity, shear thinning, and orientation, is critical to developing good processors and technicians.
