  • Patent number: 5149590
    Abstract: A ceramic filled fluoropolymer-based electrical substrate material well suited for forming rigid printed wiring board substrate materials is presented which exhibits improved electrical performance over other printed wiring board materials. Also, the low coefficients of thermal expansion and compliant nature of this electrical substrate material results in improved surface mount reliability and plated through-hole reliability. The electrical substrate material preferably comprises polytetrafluoroethylene filled with silica along with a small amount microfiberglass. In an important feature of this invention, the ceramic filler (silica) is coated with a silane coating material which renders the surface of the ceramic hydrophobic and provides improved tensile strength, peel strenth and dimensional stability. In addition, even improved results are provided when the silane coating is comprised of a fluorinated silane or a combination of fluorinated and non-fluorinated silanes.

  • Patent number: 5145737
    Abstract: The system for closure and subsequent opening of the sterilizable container is made up of a cover having its sealing layer which bonds to the cover where the sealing layer is made of a polymeric material such as high density polyethylene, polypropylene and polyester and the container, at the point where the cover is sealed to the container, is also made of the same polymeric material as the cover's sealing layer. Between 15 to 50% by weight of inert filler is used. The cover and container are joined by deep soldering so that the action of pulling the cover off of the container causes an internal breaking of the material containing the inert filler. An inert filler is incorporated into the sealing layer and can also be incorporated into the container where the cover and container are joined.
