Abstract

Thermomechanical analysis (TMA) provides valuable characterization information on the dimensional properties of a wide range of materials. Used either alone or in conjunction with other thermal analysis techniques [differential scanning calorimetry (DSC), thermogravimetric analysis, dynamic mechanical analysis, or thermoconductivity], the technique provides a large amount of valuable information on polymers and other materials that is difficult or even impossible to obtain by other analytical techniques. TMA offers a higher degree of sensitivity compared to DSC for the detection of the glass transition temperature of highly filled or highly cross-linked materials, such as composites, printed circuit boards, or brake linings. This chapter provides an outstanding overview of the principles and applications of TMA for both research and quality assurance uses.
