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 ...

Polymers are viscoelastic fluids that are either elastic or viscous, depending on how fast they flow or deformation in the process. The viscoelastic phenomenon, as shown in Figure 1, can be easily ...

The United States Pharmacopeia has stated that references to General Chapter <911> "Viscosity" will be changed to General Chapter <911> "Viscosity-Capillary Viscometer Methods," <912> "Rotational ...

According to the new market research report "Rheometer & Viscometer Market by Product (Dynamic & Torque Rotation, Oscillatory, Capillary Rheometer, Rotation, Process, Capillary Viscometer), Sample ...

LCR7000 capillary rheometers are suited for studying the viscosity of molten polymers. The redesigned model is as easy to use as earlier Dynisco models, yet offers nearly triple the dynamic range of ...

Rheology is the study of the flow and deformation of materials under applied forces, covering both liquids and solids. It examines how materials respond to stress, strain or flow, revealing ...
