221 EMI Gaskets

Fabric-over-Foam

USA Europe Asia:

UL 94HB RATED NI/CU POLYESTER TAFFETA FABRIC-OVER-FOAM

Laird Technologies’ Fabric-over-foam FoF 221 EMI gaskets provide excellent EMI shielding performance for customers where EMI issues occur. The 221 series EMI gaskets are composed of electrically conductive fabric wrapped around a thermo-plastic elastomer TPE core. They are supplied with either a conductive or non-conductive pressure sensitive adhesive PSA , and can be equipped with an Extended Release Liner ERL on the adhesive. The 221 is a UL 94HB rated product that can be created with cross-section profiles such as rectangle, D, knife, bell shapes, and others. The 221 EMI gaskets can be further customized to an application by die-cutting, hole punching, notching, etc.
• Fabric-over-Foam gaskets are RoHS compliant
• UL 94HB
• surface resistivity of < Ω
provides excellent conductivity
• effectiveness of >75 dB across a wide spectrum of frequencies
• Low compression forces allow for use of lighter materials
• is highly conductive to provide good EMI shielding and grounding
• Technologies’ proprietary coating prevents fabric fraying and fingerprinting
• with conductive or non-conductive PSA
• cross-section profiles available such as rectangle, D, knife, bell and more
• gaskets can be cut to specified lengths, kiss-cut on release liner, or mitered to form frame configurations
