  • Sealing element and method of manufacture of a sealing element
    Patent number: 12025226
    Abstract: Disclosed is a sealing element and a method of manufacture. The sealing element has a sealing surface for providing a seal against a contact surface. A sintered PTFE film is coupled to the elastomeric body, and defines the sealing surface, which is of particular suitability for a dynamic seal. The sealing film comprises a lubricious particulate material.
    Type: Grant

  • Low stress to seal expanded PTFE gasket tape
    Patent number: 7943003
    Abstract: 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 impermeable layer prevents fluid from permeating through the gasket in the radial direction.

  • Low stress to seal ePTFE gasket material
    Patent number: 7361398
    Abstract: A low stress-to-seal gasket material is described. Gaskets made according to the present invention comprise at least two tapes of porous PTFE and a substantially air impermeable layer at the interface of the two tape layers. The tape layers each have a non-porous region extending the tape length and separating two porous regions. The non-porous regions of at least two tape layers are not aligned in the z-axis direction.
