AN708-Decomposition kinetics of PET by TGA according to ASTM E1641 Private content

Determining the kinetic parameters of a decomposition is an important step to evaluate the stability of a material. Different techniques, models and standards have been developed to be able to better understand these kinetics. Here, the decomposition of a polyethylene terephthalate sample (PET) was performed using the LABSYS evo TGA 1150. The method applied was the one described by the ASTM E1641-13 standard, which uses the Ozawa/Flynn/Wall isoconversional method.
