Principle

Application of a shear rate range (in steady mode) or a strain frequency (in dynamic mode) and measurement of the correspondent resistance of the material to flow to determine viscosity and viscoelastic properties (𝜂*, G’, G” and tan𝛿) respectively.

Capabilities

  • Measurement of viscosity in a wide range of shear rates (0.01 - 1000 s-1) and temperatures.
  • Frequency sweep tests for viscoelastic materials.
  • Time sweep test to evaluate stability.
  • Temperature sweep test for screening crosslinking temperature, gelation point, …
  • Dynamic Mechanical Analyses (DMA) for phase transitions and modulus variation with temperature.
