DMA Applications in Polymers: Measuring Properties, Understanding Behavior

This webinar focuses on the use of Dynamic Mechanical Analysis (DMA) for polymeric materials such as thermoplastics, composites, and elastomers. As the understanding of viscoelastic material properties becomes increasingly important in product development and performance evaluation, the session shows how DMA can be used to characterize key parameters such as glass transition, stiffness, damping behavior, creep, and stress RelaxationWhen a constant strain is applied to a rubber compound, the force necessary to maintain that strain is not constant but decreases with time; this behavior is known as stress relaxation. The process responsible for stress relaxation can be physical or chemical, and under normal conditions, both will occur at the same time. relaxation.

Using practical examples, the webinar demonstrates how polymer behavior can be evaluated under different test conditions, including varying temperatures, humidity levels, mechanical loads, and immersion in liquid media. Participants will gain a better understanding of how to interpret DMA data and apply the results to real-world polymer testing challenges.
