Dynamic Mechanical Analysis (DMA)
DMA also known as Dynamic Mechanical Thermal Analysis (DMTA), is a method of analysis that determines the mechanical properties of a sample as a function of temperature and frequency simultaneously.
DMA also known as Dynamic Mechanical Thermal Analysis (DMTA), is a method of analysis that determines the mechanical properties of a sample as a function of temperature and frequency simultaneously.
Dynamic Mechanical Analysis is a thermal method used to provide plastic analysis or rubber analysis of virtually any sample. It can even be used to evaluate coatings on thin metal samples.
Our DMA instrument operates over a wide temperature range (-150 to 600°C) and provides multiple modes of deformation including:
Other fixtures and deformation modes of DMA Analysis may be available on request.
It is best for the sample to maintain structural integrity during the entire DMA analysis. Knowing the melting temperature of the sample, in the case of thermoplastic materials, allows the upper temperature limit to be properly set.
Only solid samples can be evaluated using DMA Analysis. The sample has to have a stiffness value within a particular range to be suitable for testing.
DMA can be used to provide plastic analysis or rubber analysis of virtually any sample. Rubber or plastic samples can be prepared to have length, width, and thickness dimensions to accommodate the operating range of the instrument.
