Rheometry Testing Services

ITA Labs uses a TA Instruments Rheometer to conduct our Rheometry Testing Services, to measure shear rheology across various materials including polymers, metals and composites.

Rotational rheometry determines the structural and compositional changes within a material, which can affect flow and deformation. A rheometer will replicate the flow and deformation that is typically found in extrusion and injection moulding. The controlling factors in flow and deformation can affect the stability and performance of a material.

The material sample is loaded into the gap in the measuring system, specifically designed to impose shear flow when rotated. Rotating, oscillating or applying a step function, which controls motor torque or position change, determines material sample characteristics.

Rheometry is commonly used for testing viscosity, however it can be used to determine other characteristics within a material, including:
