Dynamic Mechanical Analysis (DMA) Testing and Measurement Services

What is Dynamic Mechanical Analysis?

Dynamic mechanical analysis (DMA) is a technique used to study mechanical properties of objects, typically viscoelastic properties of polymer materials. Traditionally, this involves understanding the viscous and elastic mechanical properties of a polymeric material under a constant deflection. In this case, DMA is a powerful tool for monitoring the strain of a material when a dynamic sinusoidal stress is applied and allows the understanding of complex time dependent moduli.

What Properties can you Measure with DMA?

Many time-, frequency- and temperature-dependent properties of polymers can be elucidated from DMA experimentation. The storage modulus (E’ or G’) of a material can be measured, along with the loss factor and angle. By modulating the temperature with respect to a constant stress, the glass transition temperature can also be measured. Fatigue experimentation can be used to track the changes within a polymer material as it is cyclically loaded and may shed insight into its long-term behaviour.

    • Dynatex International

      I had a request for thermal conductivity information on one of my adhesives and contacted Thermal Analysis Labs. The process was very smooth – I experienced none of the issues typical of other contract labs we work with. The results were delivered on time and I have used the data in our sales literature to help my clients have success in their applications.

      Vice President of Sales

    • Shawsheen Rubber Company Inc.

      I was completely satisfied with the testing experience.

      Gary Litman,
      Vice President of Technology

    • NGK Metals Corporation

      I was well pleased with the experience. The instructions for the sample configuration was clear. The people responded promptly to questions. The lab double checked results to address any questions. The report was clear, easily understood.

    • Abbott

      I am very happy with the testing services I received from Thermal Analysis Labs. I’ve found them very responsive, and they were able to get us the data we needed to get quickly so that we could use it to validate our designs. I refer my other colleagues to them, and they’re my go-to group for thermal testing.

    • Siemens

      I’ve outsourced thermal testing of several materials to TAL. My experience has been very positive. Their professionalism shows in management, quality of work, and customer service. They are always eager to accommodate my needs and timeline. I highly recommend their services.

      Chris Ebeling,
      Thermodynamics and CFD Group Manager

    • MAE Trading International Inc

      All data and reports were very helpful and we appreciate your support; you did an amazing job to conduct the tests and confirm the reports within such a short time frame. This really helped us get out of jam and your support meant a lot to our efforts with our customer. We will certainly contact you again on these matters.

      Michael Smith,
      Managing Director

    • Newell Brands- Writing (Sharpie, PaperMate, PrismaColor, Elmer's)

      Thermal Analysis Labs has provided great service for all our materials testing needs by providing quick turn-around testing results while also providing the service for a reasonable cost. TAL’s professional approach to our material testing request has also provided great insight to the materials being tested and the best method to achieve the measurements. TAL has been an invaluable resource for our product development process.
