In most cases the additional moisture increases the plasticity of the PET melt, resulting in a higher flowability. As a result of hygroscopic behavior PET’s melt flow rate (MFR) parameters are highly ...

Magma rheology exerts a primary control on a wide range of volcanic processes, from the extraction of magma from the deep earth, during its transport towards the surface, and finally its extrusion at ...

This is because the plastic is constantly expanding or stretching in those processes. Two polymers may have identical shear flow behavior, but they could exhibit different extensional flow behavior ...
