Abstract
The present invention is an improved gasket for use in a wide variety of sealing applications. The gasket comprises a continuous, form-in-place gasket element, comprising layers of expanded polytetrafluoroethylene, that has significant tensile strength in both the longitudinal and the transverse directions. As such, the gasketing element of the present invention provides all of the operational advantages of PTFE, while being dimensionally stable, resistant to creep relaxation and providing form-in-place dimensions, thus satisfying a wider range of sealing applications than conventional sealing materials.
