Dynamic Mechanical Analysis measures the mechanical properties of materials as a function of time, temperature, and frequency. In addition to basic material properties, DMA also quantifies finished part characteristics, reflecting the important contribution that processing has on end-use performance. DMA is commonly used to measure glass transition temperatures and secondary transitions, orientation caused by processing, cold crystallization, cure optimization, filler effects in composites, and much more. DMA provides an accurate measure of material stiffness (modulus) but also other important mechanical properties such as damping, creep, and stress relaxation.
TA Instruments is the world leader in Dynamic Mechanical Analysis, offering two state-of-the art dedicated DMA instruments and additional DMA capability through our rheometers and mechani-cal test instruments. All TA Instruments DMA products feature innovative technology for force and displacement measurements, temperature control and accuracy, instrument stiffness, and ease-of-use.
