CA 2558739
A low stress to seal, unitary gasket tape is provided that is particularly suited for use in form-in-place gaskets. The gasket tape preferably comprises at least two joined porous expanded polytetrafluoroethylene (ePTFE) tapes aligned along tape side surfaces and a substantially air impermeable layer there between. The plane of expansion of the ePTFE is substantially parallel to the flange surface providing longitudinal and transverse strength. The substantially air to impermeable layer prevents fluid from permeating through the gasket in the radial direction.
L'invention concerne un joint ruban unitaire à faible contrainte d'étanchéification, qui peut être utilisé en particulier comme joint moulant. Le joint ruban de l'invention comprend, de préférence, au moins deux rubans de polytétrafluoréthylène expansé (ePTFE) alignés le long de surfaces latérales du ruban entre lesquelles est disposée une couche sensiblement étanche à l'air. Le plan d'expansion du ruban ePTFE est sensiblement parallèle à la surface de la bride et lui confère une résistance longitudinale et transversale. La couche sensiblement étanche à l'air empêche la pénétration radiale des liquides dans le joint.
