Fabric over Foam EMI Gasket Material, Laird, Chomerics® Soft-Shield® RFI and Electrically Conductive Foam Gaskets
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.
Products can be produced in almost any configuration imaginable, from cut gaskets to custom shapes often without tooling fees. Specific properties and test data are available from our world class engineering department .
