ABSTRACT:
A set for preventing flow of a fluid under pressure between a first surface and a second surface spaced-apart from the first surface. The seal is molded or otherwise formed from a composition comprising a blend of from about 79-87% by weight of a copolymer of polytetrafluoroethylene and perfluoropropylene vinyl ether, from about 10-14% by weight of polyimide, and from about 3-7% by weight of carbon fiber. The seal is interposable between the first and second surface effective to prevent the flow of the fluid therethrough.
