What Schlegel Electronic Materials does
Schlegel Electronic Materials (SEM), founded in 1987 in Rochester, New York, is a privately held materials technology company specializing in electromagnetic interference (EMI) shielding and thermal management solutions for electronic enclosures. The company invented highly conductive fabric-over-foam (FOF) shielding gaskets in 1987 and has since built one of the broadest portfolios in the industry, spanning fabric-over-foam and fabric-over-silicone gaskets, conductive nickel-copper foam, silicone elastomer gaskets (up to 120 dB attenuation), DynaShear/DynaGreen bump-technology card/cage gaskets, BandSorb cavity resonance absorbers, TimSorb hybrid thermal/EMI absorbers (OP-7400/7500/7600), Doubleshield SMT-compatible grounding pads, BeCu fingerstock, shielded windows/cans, vent panels, conductive tapes, and PermaFlow porous-film filters for water/air/sound. Thermal management offerings include thermal gap fillers (including silicone-free variants), phase change materials, thermal grease (including silicone-free grades), thermal putty, thermally-conductive ceramic insulators, and 2-part cure gap fillers. Through its wholly-owned SEM Specialty Products subsidiary and the PolyFab sub-brand, the company also supplies woven pile textiles, extruded seals, and UL 10C-certified compression seals for fenestration and industrial applications.
SEM sells directly to enterprise customers in automotive, aerospace, military and defense, medical devices, telecommunications, consumer electronics, copier/printer, fenestration/construction, and mobility (EV, rail, aviation, marine) markets under a quote-based, consultative model with technical sales engineers. Products are specified into long qualification cycles and supported by an online library of 200+ FOF gasket profile drawings with IGES 3D CAD files, plus compliance documentation spanning UL 10C, UL94-V0, IEC 61249-2-21 (halogen-free), MIL-DTL-83528-C, RoHS, and REACH. The company is a subsidiary of the eMEI Group, employs 251–500 people, and complements its direct North American sales with R&D participation in the European PARASOL Marie-Skłodowska-Curie Doctoral Network and a proprietary stripline testing capability developed with KULeuven for EMI characterization up to 40 GHz.
