DMA 861 Viscoanalyzer – Mettler Toledo

Advanced dynamic analysis of the viscoelastic properties of materials over a wide range of temperature and frequency.

What is it for ?

The DMA861 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.

Fields of application :

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

 

Available Measurement Types :

  • Determination of the real modulus (E’, G’) and imaginary modulus (E’’, G’’).
  • Calculation of the loss factor (tan δ) to quantify damping.
  • Construction of master curves through frequency/temperature equivalence.
  • Tests in :
    • Tension
    • Compression
    • Shear
    • 3-point bending (free or clamped).
