Abstract
A gasket material has a resilient core of glass fiber and a jacket of glass or other suitable fiber over said core. The jacket and core may have therebetween an essentially impermeable sheath of a chemically resistant material. The jacket has therein enough polytetrafluoroethylene in dispersed form to prevent flow of liquid therethrough. The core may have enough of the polytetrafluoroethylene dispersion therein to prevent wicking.
Claims21
A chemically resistant, resilient gasket material, said gasket material having opposed surfaces for forming a seal between a rim and a cover for said rim, said gasket material having a cross-section comprising:
- a core of glass fibers disposed at an angle to said surfaces for providing resilience to said material;
- and
- a jacket of a fiber selected from the group consisting of glass fiber, carbon fiber, graphite fiber, polytetrafluoroethylene (TFE) fiber, polymonochlorotrifluoroethylene (PMC) fiber and aramid fiber and dispersed TFE within said jacket in sufficient quantity to prevent the flow of liquid therethrough, said jacket being disposed about said core.
