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. http://web.abo.fi/instut/biofuelsGS-2/kursen/%c5A/lectures/Lectrure_Thermal%20Analysis.pdf michael shannon 12 strongWebderivative peak sharpness (wt% per oC) is improved in Hi-ResTM TGA even over conventional TGA at 1oC/minute. Furthermore, the Hi-Res TM TGA results are achieved in less time than conventional TGA results at 20 oC/minute.
