Viscosity And Viscoelasticity Of Polymer Melts
In the general polymer production processes, polymers must be melted to process them. So, a very good understanding of molten plastic’s nature to obtain successful plastic production processes. The most prominent features of polymer melts are; viscosity that is very different compared to other Newtonian fluids. And viscoelasticity is the special feature of polymer melts. Viscoelasticity Nature […]

Basic Explanation Of Viscoelasticity On Polymers
As you know from fluid dynamics, viscosity is the resistance of a fluid to flow. Elasticity is can be explained as the material’s ability to return its previous shape after a load application on it. As you understand that the Viscoelasticity term derives from these two terms. In this article we will explain the viscoelasticity […]
