WebTGA evaluation Thermogravimetry is a technique that Thermogravimetry is a technique that measures the change of mass of a sample as a function of temperature or of time. Further analysis of the weight loss steps requires the evaluation methods included in the option ‘TGA evaluation’. WebThe TGA curve of PVDF hollow fiber has essentially no weight loss before 453.2°C. The fastest decomposition temperature is 463°C (the peak temperature corresponding to the DTG curve). At the temperature of 778.3°C, the PVDF hollow fibers do not lose weight anymore. The same result is also found in the DTG curve.
