Thermal Analysis can be used for quality control and research of thermosetting materials. Just a small sample of a few milligrams is sufficient to measure the most important properties and characteristics of such materials, for example the glass transition, vulcanization, the expansion coefficient, swelling, decomposition, and elasticity.

Elastomers are employed in many industries because of their unique elastic properties. The automotive, aerospace and defense industries use elastomers for tires, tubes, dampers, coatings, and seals. Smaller parts made of elastomers can also be found in other industries. The four main techniques of thermal analysis, DSC, TGA, TMA, and DMA are ideal for characterizing such materials from –150 to 1600 °C as function of temperature or time.

The presentation covers the following topics:

  • Basic properties of elastomers
  • Typical questions
  • Thermal analysis
  • Industries and applications
  • Instrumentation and applications
    - Differential Scanning Calorimetry (DSC)
    - Thermogravimetry (TGA)
    - Thermomechanical Analysis (TMA)
    - Dynamic Mechanical Analysis (DMA)

In this presentation, we will show how thermal analysis is used to analyze elastomers and will present some typical examples of samples measured by DSC, TGA, TMA or DMA.
