Thermal Analysis can be used for the 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 specific heat capacity, glass transition, expansion coefficient, decomposition, curing, gelation, and elasticity.
Thermosets are used for components that must be rigid, insoluble and of high mechanical strength and temperature stability. Production and processing are cheaper compared with metals. The four main techniques of thermal analysis, DSC, TGA, TMA, and DMA are ideal for characterizing such materials. The chief advantage is that properties can be measured as a function of temperature or time over a wide temperature range, from –150 to 1600 °C.
The presentation covers the following topics:
- Basic properties of thermosets
- 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 thermosets and will present some typical examples of samples measured by DSC, TGA, TMA, or DMA.
