Abstract
Gaskets are sealing elements used in plate heat exchangers, which are subjected to aggressive conditions during service. In particular, the compression state, together alongside temperatures, can cause a premature deterioration of properties. To monitor and prevent such a situation, this study uses the TTS (time-temperature superposition) method and Arrhenius to predict the lifetime of FKM gaskets. For this purpose, thermo-oxidative aging is conducted at different temperatures for up to 6 months, monitoring compression set (CS) and Shore A hardness. The results indicate that the gasket can withstand periods of up to almost 300 days in service for an operating temperature of 140 °C.
