VITO in Mol

Dynamic Mechanical Analyser (DMA)

DMA measures the mechanical properties of materials as a function of time, temperature, and frequency. DMA is commonly used to measure glass transition temperatures and secondary transitions, orientation caused by processing, cold crystallisation, cure optimization, filler effect in composites,… DMA provides an accurate measure of material stiffness (modulus) but also other important mechanical properties such as damping, creep and stress relaxation.

Applications

• Viscoelastic properties (E’, E’’, tan δ)
• Glass transition
• Frequency effects
• Creep and recovery
• Stress relaxation
• Secondary transitions
• Softening and melting temperature
• Time-temperature superposition
• Aging
• Curing of networks
• Crosslinking density
• Orientation effects
• Stress-strain curves

Characteristics

• Force range: 0.0001 to 18N.
• Temperature range: -150 °C to 600 °C.
