90% of all manufactured goods produced worldwide are touched by abrasives in some way, in some part of the process. Global leadership in the field of coated abrasive splice technology requires the highest quality products and the strongest technical capabilities. Market reputation, economic risk and safety – much is at stake.
Sheldahl® creates, manufactures, and distributes technically advanced coatings, dry film adhesives, special performance tapes and engineered flexible laminates. Sheldahl® brand technical materials are renowned worldwide. Sheldahl® brand innovative material solutions began in 1955. More than 70% of abrasive belt manufactures in the world choose Sheldahl® brand adhesive and tape products.
Sheldahl’s brand splicing tapes are the undisputed, worldwide leading brand of abrasive belt splicing products. Our scientists and engineers patented Unidirectional tape technology more than 30 years ago. We continue to advance our process and product capabilities:
- Delivering innovative designs, products and services through world-class supply chain solutions, real-time information and the latest emerging technologies.
- Maintaining the highest quality standards through continuous process improvements and a zero-defect culture.
- Ensuring employee diversity and inclusion, while fostering ethical decision making.
- Embracing and driving sustainable practices wherever possible.
- Continually improving our Quality Management system and maintaining its effectiveness, to ensure full compliance with regulatory and statutory requirements.

Sheldahl was established as G.T. Schjeldahl Company by Gilmore T. “Shelly” Schjeldahl. The newly formed company produced bag-making machines.
First laminator was built to produce Schjel-Clad, a laminate of copper bonded to Mylar™ film.
ECHO I the 100-foot passive satellite (“satelloon”) that was produced by Schjeldahl was launched.
ECHO II is fabricated using Schjeldahl materials.
Production of “Schjel-Flex”, a line of precision-etched flexible circuitry processed in roll-to-roll form using “Schjel-Clad” materials.
The satellite Pegasus was sent to orbit. The meteoroid detector panels were fabricated by Schjeldahl through vacuum deposition and lamination.
Pageos 5 a 100-ft diameter satelloon produced with Schjeldahl materials was launched.
Schjeldahl participated in the Voyager program.
Schjeldahl’s flexible circuits were used by Western Electric to produce the Trimline telephone.
Schjeldahl provides thermal control materials in response to an emergency repair needed on the Skylab.
The company’s name was changed to Sheldahl, Inc. to make it easier to spell and pronounce the company name.
The Viking unmanned spacecraft landed on Mars. The bioshield that kept the spacecraft sterile during its journey was built by Sheldahl.
FLEXSWITCH®, a new line of membrane switches was introduced for use in office equipment and appliances.
Sheldahl patents unidirectional tape. A splicing system for the joining the butt ends to abrasive materials.
Sheldahl acquires Symbolic Displays Inc. of Irvine, CA to increase the scope and depth of our capabilities.
.Sheldahl acquired Cirtel / Cirpak of Irvine, CA and Nashua Flexible Circuits of Nashua, NH from BMC’s Interconics.
Sheldahl introduced Z-Link® an inter-connective circuitry system based on an adhesive that conducts electricity only in the Z (vertical) axis.
Novaclad® a copper on film flexible material was introduced.
Novalink® a multilayer circuit constructed with Novaclad® or Novaflex® and Z-Link® adhesive was introduced to the market.
ViaGrid® was developed. A Novaclad® based microcircuit substrate with a pattern of either uniform or custom placed conductive holes.
Sheldahl introduced a family of ITO films to the market under the trademark: ACCENTIA®
Sheldahl provided the world’s first roll-to-roll of patterned ITO material for the display market.
Sheldahl is purchased by Multek
Sheldahl high volume roll-to-roll ITO patterning and screen printing capability is established
Bus Bond® a family of insulation materials used as inner and outer layers in the production of laminated busbars is introduced to the market.
Q-Prime: A proprietary circuit technology with thermally conductive adhesive and a thin composite structure.
Operations of Multek in the U.S. and Philippines have been rebranded as Sheldahl Flexible Technologies Inc., a Flex Company.
