Overview
Thermomechanical Analysis (TMA) is a thermal analysis technique used to measure dimensional changes of materials as a function of temperature, time, or applied force. It evaluates properties such as expansion, contraction, softening, and glass transition, helping to understand how materials behave under thermal and mechanical conditions.
TMA is widely used in polymers, composites, ceramics, and electronic materials to assess performance and stability. It provides critical data for product design, material selection, and quality control, ensuring reliability in applications where temperature-induced dimensional changes can impact functionality.
