Only Kryoflex® is hermetic now... hermetic forever!
Kryoflex® Polycrystalline Ceramic — a multiple-phase derivative of ceramic oxide crystalline silicates — is a proprietary, patented substance 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® include resitivity of 1x1018 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® hermetic seals.
Kryoflex® technology — available only from PA&E — allows you to choose connectors, feedthrus, and electronic packaging that are literally 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 connectors and feedthrus have up to 70 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® hermetic seals to exactly match your most precise design requirements: An enormous variety of standard and custom hermetically-sealed products are available from PA&E.
- Electronic Packaging
The housings for our integrated packages can be made from a variety of metals including aluminum, titanium, stainless steel, iron-nickel alloys, and more.
- Space & Aerospace Products
High-end, hermetically-sealed connectors can include standard versions, as well as custom configurations of our industry leading DC and RF/Microwave connectors and feedthrus.
- Medical Components
Our hermetically-sealed, ceramic-to-metal terminals and connectors used in electronic life-support devices, hearing restoration components, vital organ synthetic drug secretion devices, and bone growth stimulators, are all manufactured for implant in the human body.
- Energy Products
Kryoflex® is used to hermetically-seal connectors and integrated packaging used for deep-well oil exploration and other applications where units must operate under extreme temperature and pressure, while maintaining both a hermetic seal and superior electrical performance.
