Thermal Analysis
Differential Scanning Calorimetry (DSC)
DSC is a measurement of characteristic properties of polymers such as melting point, glass transition temperature, crystallization and phase changes transitions at temperatures ranging from -80° to 250°C.
Thermogravimetric Analysis (TGA)
TGA is a characterization method that is performed on a variety of polymers, blends and polymer composites to determine changes in weight as a function of temperature under nitrogen or air environment for characterization of thermal and oxidative stability of polymers, and the amount of inorganic fillers.
Composition break down and carbon black % by TGA ASTM D297
