Study on the Thermal Stability of Polyphenylene Sulfide Filter Media by Non-Isothermal Thermogravimetry

In order to study the thermal stability of PPS (polyphenylene sulfide) filter media, by means of non- isothermal thermogravimetry, thermal degradation kinetics behavior of two kinds of PPS filter media were analyzed. The kinetic parameters of PPS filter media were obtained according to Friedman method. Thermal stability of PPS filter media was discussed. It was found that the initial decomposition temperature and activation energy of N3 sample are all higher than B1 sample, the thermal stability of N3 sample is better than B1 sample, and kinetic analysis can be used as an important method to evaluate the thermal stability of filter media.
