Dynamic mechanical multi-talent for visco-elastic properties

The versatility of the DMA 242 C is particularly clear from the variety of sample holders. Depending on the type and consistency of your sample, you can investigate the visco-elastic properties accurately over a wide modulus range. In addition to the common types of deformation, i.e. 3-point bending, single and dual cantilever bending, compression/penetration, shearing and tension, we also have a series of special sample holders available: e.g. for extremely stiff composite materials and metals or for combination with a dielectric analyzer (DEA) for curing studies. A stainless steel container facilitates measurements in various media (immersion tests). With the use of a thermostat, it is also possible to carry out reliable extended time tests at higher temperatures.
The DMA 242 C operates in the broad temperature range of -170 to 600°C. The low-temperature range is achieved with the proven, low-consumption CC 200 L liquid nitrogen cooling system. The minimal temperature gradient over a sample length of up to 60 mm in the bending mode is unique.
An intelligent purge gas system provides for a defined sample atmosphere and protects the measurement electronics from any gases evolving from the sample as well.
Frequencies from 0.01 to 100 Hz can be selected and combined with defined stress of up to 16 N and deformation amplitudes of between 0.1 and 240 µm.
The digital filtering via Fourier analysis yields an excellent signal-to-noise ratio, which means that even the smallest tanδ values can be resolved. Comprehensive, multi-dimensional calibration of the DMA system guarantees reproducible test results for the stiffness and damping (visco-elastic) behavior of your sample.
