What Marktek does

Marktek Inc. is a privately held specialty materials supplier founded in 1994 and headquartered in Chesterfield, Missouri. The company manufactures and distributes electrically conductive and EMI/RFI shielding materials — including fabrics, fibers, felts, meshes, tapes, and resistive wires — for industrial and electronic applications. Its core product lines are EeonTex™ (nonmetallic, aqueous-based conductive coatings applied to individual fibers within fabrics, yarns, and leather), Metalized Fabrics (silver, nickel, copper, and tin coatings on nylon/polyester substrates with surface resistivities below 0.1 ohm/sq), Nonwoven Scrims of Chopped Fiber, Electrically Conductive Fibers/Yarns/Threads, Fibreohm™ (nonmetallic resistive wire for MRI/X-ray and EMF measurement environments), and Metalized Fabric Tapes, Hook & Loop, and Braided Tubes. The company offers surface resistivities spanning from less than 0.01 ohm/sq to over 100 Mohm/sq, and its EeonTex™ and metalized fabric lines are REACH and RoHS compliant.

Marktek's underlying technology is a proprietary coating and material formulation capability rather than a software platform. The aqueous-based EeonTex™ process enables thin, lightweight, flexible alternatives to traditional metal shielding, with derivatives exhibiting piezoresistive (pressure/strain sensing) and microwave-absorbing properties (up to 50% absorption for thinner fabrics and over 80% for thicker felts). The company serves six primary use-case segments: EMI/RFI shielding (gaskets, tapes, enclosures, architectural linings), medical/healthcare (skin electrodes, MRI/X-ray patient sensors), antenna and RF systems, defense and security (radar-absorbing materials, reduced radar cross-section composites), static charge dissipation (ESD protection), and testing/measurement (anechoic chambers, EMF meters/probes).

The business operates on a direct-to-customer sales model with no public pricing; prospective customers are directed to contact the company by phone or email for project-specific quotes and technical consultation. Revenue is generated through one-time sales of materials, with multi-year contracts noted as a billing cadence. Distribution is direct sales with global reach self-claimed. The company is founder-led, with Arthur Henn publicly identified as the principal, and operates with 1–10 employees. It has no subsidiaries, no disclosed funding rounds, no parent company, and no public ticker.
