摘要： Improved insulative cable assemblies and methods for producing them are disclosed. The insulative cable assemblies have a conductor housed within a polymeric insulation layer expanded with expandable thermoplastic microspheres. The use of a relatively inelastic outside sheath controls the expansion of the insulative layer and assures a snug fit between the insulation and the conductor. The insulation layer is highly resilient and resistant to dielectric changes due to compression or damage from mechanical manipulation of the cable. Additionally, the ability to expand the insulative layer after cable assembly is completed provides far greater freedom in cable processing without compromising low dielectric constant.

摘要： An improved gasket particularly suitable for use in sensitive environments is disclosed. The preferred gasket of the present invention comprises at least one layer of a composite material of porous polytetrafluoroethylene (PTFE) polymer and resilient expandable microspheres. The composite material provides a number of significant advantages over existing PTFE and similar clean gaskets, including better seal under less compressive pressure, sufficient resilience to permit reuse, and retained porosity--allowing pressure equalization in the equipment to occur through the gasket itself.

摘要： The present invention is an improved material and method for use for providing diffuse reflectivity of light in backlighted visual displays, such as liquid crystal displays (LCD) employed in a wide variety of applications. By employing an expanded polytetrafluoroethylene (PTFE) comprising a microstructure of polymeric nodes and fibrils, the material of the present invention demonstrates exceptional diffuse reflectivity across a wide spectrum of visible light. Additionally, the material of the present invention provides many properties that have been previously unavailable in highly diffuse reflective material, including a high degree of malleability, moldability and flexibility, and effective reflectivity even at relatively thin cross-sections.

摘要： The present invention is an expanded polytetrafluoroethylene (PTFE) fiber with improved handling properties. Unlike previous expanded PTFE fibers, the fiber of the present invention employs a fiber of increased thickness so that the fiber is maintained in an unfolded orientation. The improved processing steps of the present invention create a fiber that has a number of improved properties, including more uniform dimensions along its length, improved compressibility and handling, and when woven into a fabric, the fabric is more easily processed, is of higher quality, and is more uniform.

摘要： The present invention relates to surfaces used to reflect light, and particularly to highly light reflectant surfaces that provide even diffusion of light for the purpose of maximizing light efficiency and/or uniformity in a luminaire. By employing an expanded polytetrafluoroethylene (PTFE) comprising a microstructure of polymeric nodes and fibrils, the material of the present invention demonstrates exceptional diffuse reflectivity across a wide spectrum of visible light. Additionally, the material of the present invention provides many properties that have been previously unavailable in highly diffuse reflective material, including a high degree of malleability, moldability and flexibility, and effective reflectivity even at relatively thin cross-sections.

摘要： The present invention is an insulation material with improved loft characteristics and methods for producing such insulation. The preferred insulation comprises a multiple layered insulation material with discrete fibers having energy expandable thermoplastic microspheres interspersed and contained therein. The use of expandable microspheres allows for (1) the introduction of unexpanded microspheres into pre-constructed insulation; and (2) expansion of the microspheres within the insulation to a diameter greater enough that the microspheres are retained in place. The insulation of the present invention exhibits many improved properties over conventional insulations, such as improved loft, better thermal insulation, improved compression resistance, and improved resilience.
