Rosand range
Capillary rheometers for process-relevant material testing.
Rosand capillary rheometers characterize the rheology of materials by extrusion under high pressures, shear rates and a range of temperatures, conditions which are directly relevant to processing. Applicable to materials from polymer melts to ceramics, and from foodstuffs to inks and coatings, a Rosand capillary rheometer enables optimization of process conditions and material properties for critical product functionality.
