Dynamic Mechanical Analysis (DMA)
Find the Right DMA Instrument for Your Thermal Analysis
Understand How Your Materials Perform Under Real-World StressStress is defined as a level of force applied on a sample with a well-defined cross section. (Stress = force/area). Samples having a circular or rectangular cross section can be compressed or stretched. Elastic materials like rubber can be stretched up to 5 to 10 times their original length.Stress

What Is Dynamic Mechanical Analysis?
XXXXX
Dynamic Mechanical Analysis (DMA) is a technique used to measure how a material responds to an oscillating mechanical force. It provides insight into a material’s stiffness, elastic and viscous behavior, damping and temperature-dependent transitions.
DMA is particularly valuable when you need to understand not just whether a material works, but how it behaves under changing mechanical and thermal conditions.

Turn Mechanical Behavior into Confident Material Decisions
With DMA, you can evaluate material performance where static testing alone may not provide sufficient insight.
- Characterize viscoelastic behavior
Understand the balance between elastic recovery and viscous deformation. - Identify transitions and critical temperature ranges
Detect Glass Transition TemperatureThe glass transition is one of the most important properties of amorphous and semi-crystalline materials, e.g., inorganic glasses, amorphous metals, polymers, pharmaceuticals and food ingredients, etc., and describes the temperature region where the mechanical properties of the materials change from hard and brittle to more soft, deformable or rubbery.glass transitions, softening behavior, RelaxationWhen a constant strain is applied to a rubber compound, the force necessary to maintain that strain is not constant but decreases with time; this behavior is known as stress relaxation. The process responsible for stress relaxation can be physical or chemical, and under normal conditions, both will occur at the same time. relaxation processes and other material changes. - Compare formulations and material variants
Support material selection, formulation development and competitive benchmarking. - Evaluate performance over temperature and frequency
Assess how a material behaves under conditions closer to real application environments. - Support development and quality decisions
Use reliable mechanical-property data in R&D, product development and quality control workflows.
What Can You Investigate with DMA?
- How does a polymer’s stiffness change with temperature?
- At what temperature does a material lose mechanical performance?
- How do two formulations compare in damping or modulus?
- What is the Glass Transition TemperatureThe glass transition is one of the most important properties of amorphous and semi-crystalline materials, e.g., inorganic glasses, amorphous metals, polymers, pharmaceuticals and food ingredients, etc., and describes the temperature region where the mechanical properties of the materials change from hard and brittle to more soft, deformable or rubbery.glass transition temperature of my material?
- How does frequency affect viscoelastic behavior?
- Is a material suitable for a specified thermal and mechanical operating range?
- Can I detect Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing, RelaxationWhen a constant strain is applied to a rubber compound, the force necessary to maintain that strain is not constant but decreases with time; this behavior is known as stress relaxation.
