Date:2016-05-14 15:12:05    Browsed:1698    Source:www.othchina.com

  PTFE gasket sheet :

  1. A chemically resistant conformable gasket which comprises:

  at least one inner layer consisting essentially of a densified expanded polytetrafluoroethylene sandwiched by

  two outside layers consisting essentially of conformable expanded polytetrafluoroethylene;

  wherein the at least one inner layer of polytetrafluoroethylene material has a higher rigidity than the two outside layers of conformable expanded polytetrafluoroethylene material, and the gasket holds its shape during handling and installation while being sufficiently conformable to provide an effective seal between sealing surfaces.

  2. The gasket of claim 1 which further comprises a plurality of said inner layers with a layer consisting essentially of conformable expanded polytetrafluoroethylene bonded between each of said plurality of inner layers.

  3. A chemically resistant conformable gasket which comprises:

  at least one inner layer consisting essentially of a densified expaneded polytetrafluoroethylene sandwiched by

  two outside layers consisting essentially of conformable expanded polytetrafluoroethylene and a filler of electrically conductive material;

  wherein the at least one inner layer has a higher rigidity than the two outside layers, and the gasket holds its shape during handling and installation while being sufficiently conformable to provide an effective seal between sealing surfaces,

  and further wherein the composite will conduct electromagnetic interference energy.

  4. The gasket of claim 3 which further comprises a plurality of said inner layers with a layer consisting essentially of conformable expanded polytetrafluoroethylene and a filler of electrically conductive material bonded between each of said plurality of inner layers.

  5. A chemically resistant conformable gasket which comprises:

  at least one inner layer consisting essentially of densified expanded polytetrafluoroethylene and a filler of electrically conductive material sandwiched by

  two outside layers consisting essentially of conformable expanded polytetrafluoroethylene and a filler of electrically conductive material;

  wherein the at least one inner layer has a higher rigidity than the two outside layers, and the gasket holds its shape during handling and installation while being sufficiently conformable to provide an effective seal between sealing surfaces,

  and further wherein the composite will conduct electromagnetic interference energy.
