FRALOCK is an AS-9100 registered and ITAR compliant manufacturer/converter of flexible materials such as adhesive tapes, films, foils, foam, rubber, specialty laminates, and custom composites. These materials are used in various
components for aircraft, spacecraft, satellites, and space based solar arrays among others. Fralock’s Technical Knowledge™ (FTK) allows us to combine seemingly incompatible materials for mission-critical applications.
ALL POLYIMIDE LAMINATES
All Polyimide Adhesiveless Laminates
Flexible and Rigid-Flexdesigns are fully encapsulated. Applications include: Antennas, Solar Arrays, Circuits, Shields, Heaters, Reflectors, Custom Composites, Shims, and Mechanical Seals.
All Polyimide Design Advantages
Robust Handling: Virtually eliminates fragility related assembly damage,
rework and delays.
Full Folding: May be folded over without affect.
No Solder joints or Connectors: Continuous panels to 120” and Full Folding can result in continuous lengths to 100’s of feet without any unreliable connections.
Fine Line/Trace and Spacing: to 1 mil, allows compact design.
Low Mass: Superior materials, lamination, trace/spacing and connector
elimination yields lower mass.
Exceptional Radiation Resistance: Retains physical, thermal,
electrical and isolation properties throughout extended mission life.
Unsurpassed Reliability with All Polyimide Fully Encapsulated Designs
All polyimide bonding eliminates the adhesive interface where most problems occur.
Full encapsulation eliminates the voids around metallic traces that create performance variables and structural discontinuities that affect durability.
Laminate bond strengths exceed substrate properties that typically
exceed 10 pli to metallic traces.
Wide operational temperature range -269°C to +351°C (Tg)
