摘要:
The invention relates to liners for air ducts. Specifically, the invention is an article comprising a porous polymeric membrane layer and, optionally, a support layer, in which the article is a duct liner adapted to be removably positioned within a porous air duct. The liner may also be used in conventional metal and plastic ducts to reduce cleaning frequency. In another aspect, the invention is a porous air duct comprising: a liner comprising a porous polymeric membrane and, optionally, a support layer; and an openwork conduit, said liner disposed within the openwork conduit.

Weather-resistant electromagnetic radiation shielding materials and structures for electromagnetic interference attenuation for electronic equipment situated in unshielded outdoor housings are described.
摘要:
A wire rope including at least one metal wire and at least one fluoropolymer fiber. Preferably, the fluoropolymer fiber is present in an amount less than about 25 weight %, and in alternative embodiments less than 20 weight %, 15 weight %, 10 weight %, and 5 weight %. The fluoropolymer fiber is preferably PTFE, and most preferably expanded polytetrafluoroethylene (ePTFE). The wire rope is useful in tensioned and bending applications.
摘要:
A composite bundle for repeated stress applications comprising at least one fiber of a high strength material, at least one fiber of fluoropolymer, wherein the fluoropolymer fiber is present in an amount of about 40% by weight or less.

摘要:
A nonwoven textile material useful in dissipating static electric charges containing an electrically conductive polytetrafluoroethylene fiber. An amount of a synthetic fiber may be intermixed with the electrically conductive polytetrafluoroethylene fiber to produce the static dissipative textile material. The nonwoven static dissipative textile material may combine with a porous polymeric membrane to form nonwoven fabric laminate.The nonwoven textile material is useful as a filtration media and may be fabricated into a filter bag.
