Dynamic Mechanical Analysis (DMA)

DMA is used to measure various mechanical properties like viscoelastic properties, fatigue, glass transition, temperature and creep behaviour. The Metravib DMA has the broadest frequency and highest force on the market.

Metravib DMA+ 300, 1000, 2000

The Metravib DMA+ line represents the most advanced scientific design in dynamic mechanical analyzers. Higher forces, higher frequencies, higher sensitivities, more information, and better material characterization. That’s what Metravib provides, and what C-Therm is here to deliver.

C-Therm is the exclusive distributor and partner for Metravib DMA in the United States and Canada. If you’re ready to discuss, so are we.

    Not a Traditional DMA

    For many elastomer and composite researchers, viscoelastic properties are vital material performance characteristics. For many labs, the window of data is so small that they rely on extrapolation, super-positioning, and temperature-frequency master curves to make assumptions about their materials. 

    These problems arise in materials with extremely high modulus changes. When the stiffness change is drastic, most instruments cannot detect this entire range. This leads to further assumptions being made about the materials and introduces a great amount of risk in the development and reporting of mechanical properties. 

    Furthermore, the data they are seeing is smoothed by software to make up for the lack of sensitivity in the equipment. This sets a dangerous precedent; how can you be truly confident in your data when you’re seeing such a small and distorted piece of the picture? 

    Metravib is Different

    The solution lies in getting access to a wider range of your material’s response, a larger window frame looking into the viscoelastic properties of polymers and elastomers. With a higher frequency range, our master curves are more accurate. With access to the raw data, you are seeing the true curve, not smoothed ones, and by having a higher force range and auto control, you can see up to 7 decades of modulus change in a single experiment. 

    The Metravib DMA+ series is the only line to offer fully integrated and highly functional automation through Xpander. You can run your system 24/7 without human intervention. 


    Why Metravib is the Best DMA

    Innovative Design

    High-rigidity-one-piece mechanical frame ensures the accurate measurement of the specimen viscoelastic characteristics because the deformation measured corresponds to the material specimen and not to the mechanical test frameAir bearing and electrodynamic shaker technology unlocks excitation amplitude capabilities are optimized at high frequency because there is no friction, no suspension stiffness and continuous ventilation of the gap body. 

    Built with Users

    Due to specific developments made for elastomer customers to deal with their nonlinear mechanical behavior, specific functions have been developed and improved to match with the growing expectations of scientists and engineers. These functions represent major benefits for performing advanced testing of a large variety of polymer and advanced materials. 

    Highest Force Range

    Force range: 300, 1000, 2000 Newtons (peak to peak) allows users to extend their testing capabilities and have a larger diversity of specimen geometries. 

    Multiple Tests, One Instrument

    DMA, high frequency, creep, stress relaxation, fatigue, crack growth, calorimetry modes on a single instrumentBroad selection of specimen holders for multiple specimen geometries and dimensions. 

    Largest Frequency Range

    Frequency range from 0.00001 Hz to 1000Hz . The high rigidity mechanical frame design implies testing capabilities over an extended frequency range; an additional accelerometer measures continuously the acceleration measured on the test frameMaster curves computation using equivalence frequency/temperature law make it possible to use the data over an extended frequency range from the original testing range. 

    Powerful Software & Experimental Control

    Simultaneous static and dynamic control with combined scanning on temperature ramps (temperature/strain/stress) up to 3 in one single test. 

    Efficient auto control mode to switch from strain/displacement to stress/force control automatically. This makes it possible for a continuous test over a huge range of modulus (up to 7 decades). 

    Full trace-ability of test conditions because you have access to the real data points.
