DMA Measurement · Dynamic Mechanical Analysis Instruments · Solid Viscoelasticity Testing Equipment

Dynamic Mechanical Analysis (DMA) is a testing method used to evaluate the viscoelastic properties of solid materials such as resins, rubber, composite materials, and films under varying temperature and frequency conditions. A DMA instrument applies small periodic deformations to the sample and analyzes storage modulus (E’), loss modulus (E’’), and loss tangent (tanδ), enabling precise measurement of glass transition temperature (Tg), heat resistance, and vibration damping characteristics. This technology is essential for product development and quality control, including methods for measuring the glass transition temperature of resins, durability testing of rubber, and stiffness evaluation of composite materials. It is widely used in industries such as automotive for heat resistance verification, aerospace for lightweight design, electronics for reliability testing, medical devices for safety evaluation, and packaging for environmental resistance testing. Recently, advanced DMA instruments have emerged, supporting micro-sample testing, dynamic mechanical analysis under high and low temperature environments, and models equipped with humidity control functions. These innovations enable more sophisticated research and development, such as thermal property analysis of polymers and frequency-dependent evaluation of composite materials. This category introduces the best DMA instruments for evaluating the viscoelastic properties of solid materials, including guidance on selecting DMA equipment and practical application examples of dynamic mechanical analysis.
