For more than 65 years, Sheldahl has designed and manufactured custom flexible printed circuits and advanced materials that connect and power new possibilities across aerospace, automotive, medical, and industrial markets. Today operating as Multek Flexible Circuits, a Flex company, Sheldahl employs 800+ people across more than 350,000 square feet of manufacturing space and produces over 25,000 miles of product annually.

Sheldahl's space heritage dates back to NASA's first satellite programs and every era of crewed spaceflight since. Its thin-film thermal control materials have flown on missions worldwide, and its engineers designed and developed the sunshield materials protecting the critical electronics aboard the James Webb Space Telescope. The company's aerospace thermal control materials are recognized industry-wide for reliability in the extreme thermal and vacuum environments of space.

Beyond aerospace, Sheldahl's flexible circuits, printed electronics, unidirectional tapes, and optical materials serve automotive electrification, healthcare wearables, industrial abrasives, human-machine interfaces, and smart packaging. Core capabilities span roll-to-roll automated processing, printed polymer thin film, screen printing, vacuum deposition, adhesive formulation and laminating, and precision circuit finishing and assembly.
