More flexibility, higher conductivity, and easier installation

Schlegel Electronics Materials' (SEM) expanded line of Conductive Tapes meets the customer needs for flexibility, higher conductivity, and easier installation. They are vailable with conductive and non-conductive adhesives and in a wide range of widths.
Typical applications include cable Shielding terminations and joining metal panels together at the seams of an enclosure. Foil tapes are a cost-effective shielding solution for a wide range of uses. They can be particularly useful during the development and test phases of projects to be used as "fixes" for EMI problems.
SEM's masked conductive tapes are also available and can be used as a gasket substrate on painted or stove enameled enclosures.

Also available are special purpose adhesive tapes to include:
Pressure sensitive adhesive die-cuts
High-tack adhesive die-cuts
Low residueadhesive die-cuts
Silicone adhesive die-cuts
Insulation adhesive die-cuts
Heat resistive adhesive die-cuts
SEM's Conductive Tapes feature superior shear strength, 7.6 kPa (72+ hours @ 1.1 psi) in accordance to (PSTC #7) ASTM D 3654, and peel strength, 10.2 N2.5 cm. (36.07 ozinch width) in accordance to PSTC #1) ASTM D 3330, when compared to other EMI shielding tapes. This is made possible by a unique, cross-linking acrylic based, conductive Pressure Sensitive Adhesive (PSA) that also allows the tapes to be designed into higher temperature applications. The PSA is fire-rated to UL 510, and excessive pressure is not required for application to the end unit. There is now an easy-to-apply tape to fit most every EMI shielding design need.

Information Technology Equipment and other electronic devices must comply with various international radiated emissions and susceptibility requirements. Under specific conditions, FCC part 15 (US) requires such equipment to pass stringent regulations up to 40 GHz. Most unintentionally-radiated emissions are from field leakage at various chassis external interfaces, or from unbalanced differential signals; containment of both require shielding materials to provide a low impedance path despite the broadband andor high frequency operation of such devices. Simultaneously, these electronic devices are sensitive to various susceptibility requirements, including electrostatic discharge (ESD, e.g., IEC 61000-4-2), and, in some cases, must resist to applied voltages as high as 15 kV. In this instance, the same shielding materials must also feature a very low impedanceresistance at very low frequencies to ensure a harmless discharge path exists to allow the charge to flow from the IO connectors to the exterior of the chassis, and then safely away from the devices.

Schlegel Electronic Materials (SEM) introduces ORS-II, a new series of gaskets specially designed for broadband applications. By combining its famous nickel copper plated conductive foam and its high-end nickel copper C12 flexible fabric cladding, ORS-II offers minimal surface resistance to achieve superior grounding and shielding results at low frequencies. By offering excellent Z-conductivity to close the cavities in the chassis openings, ORS-II also ensures substantial shielding performance at high frequencies. ORS-II is available in a variety of thicknesses, which are die-cut to customer specifications, for a durable highly conductive product in all X-Y-Z axes. In addition, shielding efficiency is achieved with less sensitivity to compression variances than other traditional shielding products. ORS-II is available with a UL94-V0 flammability rating and complies with RoHS 2.0 European Directive and SVHC Policy (REACH).

Schlegel Electronic Materials (SEM) introduces NEW CF Conductive Foam. SEM CF foam, a highly resilient Nickel-Copper polyurethane foam is sandwiched between SEM's knitted and non-woven fabrics to form industry leading die-cut gaskets. CF material is ideal for applications that require conformity with excellent cavity-to-cavity EMI shielding, superior conductivity at low compression forces and better effectiveness at very high frequencies. CF foam-based gaskets are precision die-cut with either conductive or non- conductive pressure-sensitive adhesive (PSA).

Schlegel Electronics Materials (SEM) line of silicone gaskets provides shielding capability in diverse markets and applications, including the military, aerospace, medical, fluid seal, environmental and microwave applications. Our silicone elastomers are specifically designed for gasketing applications that require high levels of attenuation up to 120 db.
SEM is renowned for its high quality EMI shielding gaskets. We provide a full family of products to meet a wide spectrum of shielding needs. Our silicone gaskets meet customer needs in a variety of markets, with very competitive pricing. Engineers can now fulfill all their shielding needs from one manufacturer, rather than having to go through multiple distributors or resellers.
Silicone, the base material for elastomers, has environmental sealing properties. Shielding is achieved by incorporating various media in the silicone, depending on the product. Wire is used to provide conductivity in the oriented silicone line and a non-corrosive particle is added to the extruded parts. Because conductive elastomers can be extruded, many different profiles and lengths can be made to suit any application

Schlegel Electronic Materials introduces DynaGreen DynaShear: an innovative EMI shielding gasket family for the shielding of modules in cardcages environment that is able to offer superior features over metal fingerstocks and current Fabric-Over-Foam gaskets. DynaGreen DynaShear utilizes the, now famous and efficient, bump technology. DynaGreen is Halogen Free version of DynaShear which compliance with IEC 61249-2-21 (

Schlegel Electronics Materials (SEM), the pre-eminent manufacturer of fabric over foam EMI shielding products, offers a complete line of quality beryllium copper (BeCu) EMI gaskets. The addition of the BeCu gaskets to SEM's extensive portfolio allows SEM to be your exclusive EMI shielding supplier, to help you meet or exceed your global requirements for electromagnetic compatibility (EMC).

The mechanical spring characteristics of BeCu EMI gaskets offer superior shielding effectiveness. These gaskets offer consistent performance and yield superb electrical spring contact within this industry.

SEM provides all the popular standard styles and sizes of BeCu gaskets. The gaskets operate in spaces from 0.010 inches up to 0.500 inches.
