Abstract
This paper dicusses a recently developed approach for evaluating sheet gasket performance at elevated temperature that is based on gasket weight loss during thermal exposure. Using simple testing devices, strong correlations are shown to exist between weight loss and the change of the most important gasket properties during aging, namely: thickness change, tensile strength, tightness, and relaxation of the initial compression stress. These correlations permit a better understanding of the fundamental mechanisms involved in the degradation process of elastomer bound sheet gasket materials and have lead to the development of an aging parameter (Ap), based on on weight loss, that succesfully combines the time and temperature effect.
Through the use of gasket weight loss and Ap, the influence of some important parameters on the degradation rate of the gasket is investigated. These include: aging atmosphere, gasket width, initial compression stress, and the internal gas media. Finally, a method of characterizing elevated temperature gasket performance with a temperature index is proposed.
