The Discovery series Hybrid Rheometer (HR-2) from TA Instruments offers precise measurements of both viscosity and viscoelasticity of various materials, e.g., high viscosity fluids, pastes, polymer solutions and melts, and soft solids and as a function of temperature. Typical applications include viscosity measurements of LED encapsulants, solder pastes, fluxes, underfill, die-attach adhesives, glob top encapsulants, etc. for the electronic packaging industry; curing profiles of thermoset plastics and UV-curing adhesives and encapsulants, and rheology and viscoelasticity of polymers.

Available Geometries

Parallel Plate Geometries (20 mm and 40 mm)

Available Lower Plate
