Conductive EMI Foam Gasket Products

Marco Rubber Ohmerics® EMI RFI Shielding Fabric over Foam Gasket materials are cost effective alternatives to Chomerics® Soft-Shield® consisting of electrically conductive coated polyester woven over a highly compressible and resilient polyurethane foam used to form physical sealing barriers as well as providing EMI and RFI shielding electronic equipment from unwanted emissions or noise.

• Our most common material configurations are UL Certified flame retardant, RoHS compliant and Halogen free.
• Abrasion resistant metalized fabric shows virtually no degradation in Shielding performance after 800,000 cycles.
• High performance urethane foam core provides low compression set ensuring long term sealing performance.
• Available in a wide range of shapes and profiles with conductive or non-conductive pressure sensitive adhesive.

Foam Gasket Shapes

Foam gaskets are available in a variety of different shapes. The specific shape of the foam gasket can provide better functionality in particular applications.
