摘要： A thermally conductive interface is provided suitable for thermal conduction, especially between electronic components. The preferred thermally conductive interface comprises an open structure fluoropolymer material, such as expanded polytetrafluoroethylene, with uncoated thermally conductive particles attached to solid portions thereof. The interface has numerous benefits over previously available material, such as improved thermal conductivity, high conformability, better compressibility, inherent porosity so as to provide air relief, improved stress relief, and high material compliance and resistance to fatigue during thermal cycling.

摘要： A method of using an improved catalytic filter material for removing contaminants such as NO.sub.x from a fluid stream. The filter employs composite fibers of expanded polytetrafluoroethylene (PTFE) filled with catalytic particles. The composite fibers are chopped into staple fibers and made into a felt material. Preferably, the felt material is then laminated on at least one side with a protective microporous membrane. The combined filter removes both macro-particles, such as dust, from the filter stream before the dust can clog active catalytic sites and effectively catalytically coverts undesirable contaminants in the fluid stream to acceptable end products.

摘要： An improved low noise electrical signal transmission cable is disclosed. The cable employs an insulative layer of expanded polytetrafluoroethylene (PTFE) which is bonded in fixed relative position with a surrounding shield layer through use of an adhesive, such as fluorinated ethylenepropylene (FEP) or perfluoroalkoxy polymer (PFA). The bonding process reduces the separation of layers which can sometimes occur with expanded PTFE insulative cables and avoids the generation of unwanted triboelectric signals that can result from such separation.

摘要： The present invention provides improved compositions of expanded polytetrafluoroethylene (PTFE) and similar polymers and methods for forming and using such compositions. In its preferred embodiment, the present invention employs a mixture of PTFE and expandable thermoplastic microspheres. Through application of an energy source to the mixture, a coherent three dimensional expansion of PTFE can be achieved. The expanded mixture has many of the same beneficial properties of mechanically expanded PTFE and numerous properties previously unavailable with expanded PTFE products.
