A study on compressive creep behavior of ACM rubber for automotive engine gasket was performed using TMA thermal analysis. From the results of isothermal measurements with constant load of 1 N at several different temperatures of 160, 180, 200, and , compressive creep data at the given temperatures were obtained, and therefrom, shift factor () and master curve at reference temperature of were obtained using time-temperature superposition principle (TTSP). and of WLF (Williams-Landel-Ferry) equation were calculated through the WLF plot as -1.107 and 11.571, respectively. From this, life time of ACM rubber at was predicted as about 24,000 hrs.
