TMA is a technique in which the dimension of a substance under negligible load is measured as a function of temperature in a
specified atmosphere. TMA is therefore often used to determine the (linear) coefficient of thermal expansion (CTE) of a material. Thermal properties such as the glass transition temperature (Tg) can also be measured. Using a specific penetration probe, the softening point of a material can be evaluated as well.
