Thermomechanical Analysis (TMA)
TMA is a laboratory testing method that measures the dimensional changes in materials as they are heated or cooled. The TMA analysis involves applying a mechanical load to a sample while it undergoes thermal cycling.
Coefficient of Thermal Expansion (CTE)
CTE is a measure of how much a material expands when heated. Accurate CTE measurements are essential for designing products that can withstand varying temperatures.
