TMAThe stretching mode is used to apply a tensile load to thin films, sheets, or fiber specimens to observe their expansion/contraction behavior, measure their coefficient of thermal expansion (CTE), and if the sample is a polymer, measure itsglass transition temperature（Tg）。 When measuring in tension mode, the sample needs to be installed onto the fixture (Figure 1) first, and then placed on the TMA body. When installing the specimen, a tensile specimen fixture kit (Figure 2) is required. After the sample is fixed in the fixture, it is loaded into the tensile probe of the TMA body, and the length of the sample (initial length L0) is measured through the automatic length measurement function. For detailed instructions on the operation steps and methods, please refer to the video.
