Dynamic Mechanical Thermal Analysis (DMTA) – PerkinElmer DMA 8000

The PerkinElmer DMA 8000 is a high-performance instrument used to characterize the viscoelastic properties of materials as a function of temperature, frequency, time, or applied stress. By measuring the material's response to a controlled oscillatory force, DMTA provides detailed information on stiffness, damping behavior, and molecular mobility, making it one of the most sensitive techniques for investigating thermal and mechanical transitions.

The technique is widely employed for the characterization of polymers, composites, elastomers, coatings, and biomaterials, enabling the evaluation of structure-property relationships and material performance under real operating conditions.

Key capabilities:

  • Determination of storage modulus (E'), loss modulus (E''), and tan δ
  • Accurate measurement of glass transition temperature (Tg)
  • Analysis of viscoelastic and damping properties
