Fralock- Corporate Headquarter, Valencia

Since 1967 Fralock has helped customers design, develop, and manufacture specialty engineered materials solutions for high-reliability applications in demanding environments. Today, Fralock is a solutions provider of components made with thin films, foils, foams, tapes, specialty laminates, elastomers, and flexible polyimide etched thermofoil heaters and cables. We offer a unique all-polyimide lamination technology using no adhesives called Adhesiveless Lamination Technology (ALT). ALT circuits are lightweight, eliminate delamination, enable full folding, and are ideal for use in aerospace and other applications requiring low mass, flexibility, resistance to environmental stress, durability, and low outgassing. Fralock is the sole worldwide licensee and manufacturer of DuPont Cirlex® (a thick adhesiveless polyimide) and exclusive distributor of DuPont White Kapton.

Typical applications are thermal interface componentsthermal blocks, electrical insulation, shims, rings, seals, gaskets, EMI/RFI shielding, flexible polyimide heaters, a variety of rechargeable battery components, and other precision laser and die-cut parts.
