PVC Measured by DSC and TGA - METTLER TOLEDO
TGA measurement: Heating from 30 to 300 ºC at 10 K/min. Atmosphere: Nitrogen, 50 cm 3 /min. PVC is a polymer that is sensitive to heat. It decomposes with the formation of HCI. The characteristic features are glass transition temperature and the temperature at which degradation begins (which is a measure of its stability toward heat).
TGA curves of PVC and internally plasticzied PVC materials.
Internally plasticized poly (vinyl chloride) (PVC) materials are investigated via grafting of propargyl ether cardanol (PEC). The chemical structure of the materials was studied by FT-IR and 1H...

Thermal Characteristics, Stability, and Degradation of PVC …
2023年11月2日 · TGA results indicated that the PVC nanocomposite films with 6 wt% of SiO 2-NPs presented the highest thermal stability. Thermal properties can be improved by other types of metal oxide NPs. Bonadies et al. studied the effect of calcium carbonate NPs (CaCO 3 -NPs) and surface modifiers on the thermo-mechanical and gelation properties of PVC ...
is obtained by coupling TGA to a mass spectrometer so that the evolved decomposition gases can be identified. Figures 1 and 2, for example, show the results for polyvinylchloride (PVC) in inert (helium) and reactive (air) atmospheres respectively. The TGA weight loss profiles indicate that multistage decomposition processes are occurring. In both
