Only Kryoflex is Hermetic Now… And Forever!
Kryoflex polycrystalline ceramic — a multiple-phase derivative of ceramic oxide crystalline silicates— was developed by PA&E as a direct replacement for conventional compression glass and metallized alumina ceramics.
Chemically active Kryoflex provides, by means of oxygen pinned valence bonding, a direct union during the fusion processing of a ceramic to metal entity. This unchanging chemical and mechanical bond is enhanced by Kryoflex’s randomly organized crystalline structure, which allows this unique material to relieve stresses from within.
Electrical properties of Kryoflex ceramic to metal seals include resistance of 1×1018 ohms/cm, with easily maintained resistance values exceeding 50,000 Megohms — even in micro-miniature designs. Stand-off voltage capability is such that breakdown will always occur in the air media surrounding the terminal … never through the dielectric.
Neither Vibration — Nor Mechanical Thermal Shock — Will Degrade Kryoflex Ceramic-to-Metal Hermetic seals.
Kryoflex technology allows you to choose connectors, feedthrus, and electronic packaging that are custom-built to withstand extreme temperature, pressure, and harsh environments, and hazardous chemicals that destroy lesser materials.
We Call Our Sealing Technology Kryoflex … You Call it “Bulletproof”
The Kryoflex family of materials has adjustable coefficients of linear expansion, allowing application to a huge variety of shell and conductor materials. No formers are added, so this material remains useful as insulator from 400°F to +1,400°F with no loss of hermetic integrity.
Because Kryoflex seals directly to copper alloys, our have many times the current-carrying capacity of conventional products. When used with aluminum, Kryoflex permits hermetically-sealed connectors to be robust and lightweight, while using copper conductors. (For applications requiring greater strength, Kryoflex works well with titanium, stainless steel or Inconel shells along with platinum, platinum-clad titanium, or Inconel pins.)
Choose Kryoflex to exactly match your most precise design requirements: An enormous variety of standard and custom hermetically-sealed products are available from PA&E.
