Fabric over Foam Gaskets



For outstanding control of EMI, Schlegel Electronic Materials EMI gaskets provide the perfect fit. Made from resilient open-cell urethane foam encased in conductive fabrics, Schlegel Electronic Materials gaskets fit securely in even small gaps and uneven joints. Lightweight and flexible, these EMI shielding gaskets are ideal for a variety of applications from portable electronics units, servers and computers toperipherals and large enclosures. Schlegel Electronic Materials EMI shielding gaskets are non-abrasive to conductively plated and painted surfaces, and they maintain galvanic compatibility with a range of surfaces.


These gaskets are tested with their conductive fabric to meet UL 94-V0 and HB recognitions.

Schlegel Electronic Materials offers over 120 different profiles to meet all of your shielding needs. From standard square and rectangular to C-fold to D-shape, L-shape, P-shape, U-shape, and more, Schlegel Electronic Materials can design tailor-made shielding gasket to meet your needs.

For easy installation, Schlegel Electronic Materials gaskets are offered with, durable self-attaching inserts, clips, push-rivets or pressure-sensitive adhesive. Whatever the EMI shielding challenge, Schlegel can help you to solve your problems.


Schlegel Electronic Materials has always been on the forefront of fabric over foam technology. Today fabric over foam continues to be at the core of our product line. We offer a variety of fabrics including:
 
1: NiCu-C22: Nickel-Copper plated polyester ripstop fabric with Schlegel protective top coating.
3: NiCu-C70: Nickel-Copper plated polyester ripstop fabric with Schlegel protective top coating.
4: NiCu-C12: Nickel-Copper plated polyester plain weave fabric with Schlegel protective top coating.
7: SnCu-C50: Tin Copper plated nylon plain weave fabric with Schlegel protective top coating.
9: Ag-C2: Silver plated nylon ripstop fabric with Schlegel protective top coating.

 Fabric over Silicone EMI Gasket
      

  • A well-respected leader in the EMI Shielding industry,introduces Fabric over Silicone EMI Gaskets (FoS) for high temperature applications. FoS has been developed with a new flame retardant formulation providing EMI shielding gaskets with UL94-V0 grade (Underwriters Laboratories lnc.) and Halogen Free according to IEC 61249-2-21 (<=900 ppm chlorine,<=900 ppm bromine and 1500 ppm max. halogens) .

 

  • Fabric over Silicone EMI gaskets provide low compression forces, low compression set and an operating temperature that can be up to 125℃ (257℉).

 

  • Combined with Highly flexible SEM fabrics NiCu-C12 or NiCu-C70, Fabric over Silicone gaskets still feature over 70dB attenuation at 40 GHz (SEM Stripline method)making this product ideal for on-board shielding or high temperature environment .Fabric over Silicone is currently available for all the SEM rectangular profiles.
