Dynamic mechanical analysis is a sensitive method for exploring the structure, processability, and end-use performance of rubber and elastomeric materials. It enables characterization of the structural differences between materials and provides information about how the materials will process. Such information is important both for product development as well as process design and optimization. Most rubber materials are viscoelastic and full characterization of a material’s rheology requires elasticity information in addition to viscosity information. Dynamic mechanical analysis (DMA) is a uniquely powerful method because it measures both properties simultaneously. It measures the mechanical properties of a sample as it is deformed over a range of stress, strain, time, and temperature under different modes of the deformation such as tension, bending, compression, and shear. The KnowHow Webinar will exhibit how DMA characterization techniques are useful for evaluating the rubber and elastomeric materials to provide quantitative and qualitative information about the performance of the materials.
