Instrument
Rosand Precision Advanced Capillary Extrusion Rheometer.
Analysis target
The determination of the non-linear viscosity function in shear. The data provide information about polymer flow in processing operations such as extrusion and injection moulding.
Sample prerequisites
The technique is applicable for polymer melts
Analysis characteristics
The Rosand instrument is a floor standing capillary rheometer featuring a robust "H" frame design to allow operation under high loading conditions. Twin bores enables absolute shear viscosity measurements without the need for corrections for entry and exit flows.
Sample requirements
Typically at least 100g needed.
