Dynamical mechanical analyzer (Perkin Elmer, DMA 8000)
DMA mechanically causes deformation of the sample and measures its response. It enables the measurement of Tg and secondary transitions, the influence of frequency on dynamic and loss modules and Tg, the influence of fillers, additives and adhesives, the influence of technological processes, dimensional stability, creep and relaxation of tension. The samples are prepared with a precision saw with a diamond blade, since they must be cut off completely straight.
