DMA+300 Viscoanalyzer – Metravib

Advanced dynamic analysis of the viscoelastic properties of materials over a wide range of temperatures and frequencies.

What is it used for ?

The DMA+300 viscoanalyzer is used to :

  • Characterize the viscoelastic properties of solid materials under different mechanical and thermal conditions.
  • Analyze mechanical transitions (glass transition, hardening, softening).
  • Evaluate mechanical stability as a function of temperature and time.
  • Optimize formulations of polymers, foams, composites, and gels.

Areas of Application :

Polymers, composites, biomaterials, automotive industry, aerospace, pharmaceuticals.

 

Available Measurements :

  • Determination of the real modulus (E’, G’) and the imaginary modulus (E’’, E’’).
  • Calculation of the loss factor (tan δ) to quantify damping.
  • Construction of master curves using the frequency/temperature/WLF/TTS equivalence.
  • Tests include :
    • Tension
    • Compression
    • Shear
    • 3-point bending (free or fixed)
  • Effect of humidity on the mechanical properties of the sample.
