Decomposition Temperature
Description
Simultaneous Thermal Analysis (STA)
Simultaneous TGA/DSC measurements both heal flow and weight changes (TGA) in a material as a function of temperature or time in a controlled atmosphere. Simultaneous measurement of these two material properties not only improves productivity but also simplifies interpretation of the results. The complimentary information obtained allows differentiation between endothermic and exothermic events with no associated weight loss (e.g. melting and crystallization) and those that involve a weight loss (e.g. degradation).
Thermogravimetric Analysis (TGA)
Thermogravimetric analysis (TGA) is used primarily for determining thermal stability of polymers. The most widely used TGA method is based on continuous measurement of weight on a sensible balance (called a thermobalance) as sample temperature is increased. In air or in an inert atmosphere. Weight loss may arise from evaporation of residual moisture or solvent, but at higher temperatures it results from polymer decomposition.
