Dynamic Mechanical Analysis of Silicone Rubber for Cold Temperature Applications

Presented by Dr. Travis Parkman


Rubber materials are used across different industries, such as medical, electric vehicles (EVs), and aerospace. However, not all rubber materials have the same properties and performance under different temperatures. The glass transition temperature (Tg) is a critical parameter that indicates the temperature range where rubber materials change from a glassy state to a rubbery state. The Tg indicates the temperature limit for rubber performance, including elasticity, durability, and damping. Therefore, it is essential to measure the Tg of rubber materials accurately and reliably. One of the most effective tools to measure the Tg of rubber materials is Dynamic Mechanical Analysis (DMA). However, different types of rubber materials may require different types of DMA instruments, depending on their stiffness and force range.

This webinar will demonstrate how a high-force DMA (Metravib) can be used to measure the Tg of rubber materials with a low Tg value, including silicone rubber and butadiene rubber. You will learn the basic concepts and best practices of designing a DMA temperature sweep test. You will also see how the Tg of different rubber materials can be compared and analyzed using the DMA data.
