Abstract: A spiral wound gasket includes a resilient sealing element including spirally wound, alternating layers of metal banding and winding fill material that incorporates a significant quantity of talc with quantities of fiber and binder. Either or both of an outer guide ring and inner guide ring may extend from peripheral outer and inner surfaces of the sealing element. Embodiments of the gasket overlay one or both axial faces of the sealing element with a layer facing material that incorporates a significant quantity of talc with quantities of fiber and binder.

Abstract: An extreme temperature gasket material capable of withstanding temperatures in excess of 850° F. is provided. The extreme temperature gasket generally includes an inorganic filler, an inorganic fiber, and an organic binder. In some embodiments, the inorganic filler is from 75 to 90 wt % of the gasket material and can include submicron-sized talc particles. The inorganic fiber can be from 5 to 20 wt % of the gasket material and can include silicic acid fiber. The binder can be a latex emulsion and can be present in the gasket material in the range of from 1 to 5 wt % of the gasket material. The gasket material also can include additives, such as flocculant and defoamer. In some embodiments, the amount of organic material present in the gasket material is limited to less than 5 wt % of the gasket material.
