A gasket formed from a perforated core sheet having a first facing layer formed from a material having a relatively high degree of thermal conductivity on one side thereof and a second facing layer formed from a relatively compressible, non-asbestos gasket material on an opposite side thereof. The facing layers are attached to the core by mechanical retaining means. The retaining means can be formed as a pair of opposed tangs on opposite sides of each perforation in the core or as a dome-shaped structure having an aperture formed in an end thereof.

Two material non-asbestos gasket and method of making the same

A composite aluminum faced, expanded graphite gasket includes at least one layer of aluminum mechanically secured to an expanded graphite layer. A plurality of projections or lugs extend from one surface of the aluminum layer and are mechanically clinched to the graphite layer to secure the layers together. The exposed surface of the aluminum is coated with a resilient sealing compound. A gasket including two aluminum layers mechanically clinched to the faces of the graphite layer as well as a method of fabricating both gasket configurations are also set forth.

Aluminum faced expanded graphite gasket and method of making same

An anti-stick, non-liquid absorbing laminated gasket and a process for its preparation are disclosed in which a metallic base sheet has a bonded fibrous layer adhered to at least one face of the sheet. The fibrous layer contains a liquid-impermeable resinous impregnant and an anti-stick coat disposed along an outer face of the fibrous layer. The resinous impregnant may extend to the outer face of the fibrous layer while leaving fibers thereof exposed to which the anti-stick coat adheres. Or the resinous impregnant may extend beyond the outer face of the fibrous layer to form a skin and the anti-stick coat adheres to the extension of the impregnant after it is tackified by an organic solvent.
