Laird Technologies specializes in quick turnaround of custom shapes and sizes of EMI shielding gaskets. If you don’t find exactly what you need, our engineers will help you design the right solution to your shielding problem.

A sampling for standard profiles are shown; custom configurations and sizes can be designed to meet your specific requirements.


  • Shielding effectiveness of >100dB across a wide spectrum offrequencies (MIL-STD 285 mod.) (See Shielding Effectiveness chart under More Images).
  • Extremely low compression forces allow for use of lightermaterials (See Force Displacement Resistance chart under More Image).
  • Low Surface Resistivity of <0.07 ohms/squareprovides improved conductivity (ASTM F390).
  • Wide range of flame retardant gaskets available(UL recognized per UL94 V0 or UL94 HB). UL yellow cardsavailable on request.
  • Abrasion resistant metallized fabrics show virtually no degradationin shielding performance after 1,000,000 cycles (ASTMD3886).
  • Urethane & Thermoplastic Elastomer (TPE) cores provide lowcompression set ensuring long-term reliability of gasketperformance. Contact Engineering for profile specific data.
  • Service temperatures from -40°F to 158°F(-40°C to 70°C).
  • Available in Nickel/Copper (Ni/Cu) and Tin/Copper (Sn/Cu) toensure galvanic compatibility with a wide variety of host materials.Both versions display no significant performance degradationafter environmental exposure per the Accelerated AgingTest (ASTM B845).
  • Prototype samples can be provided quickly utilizing laser technology,CAD/CAM equipment, and customer supplied drawingsin DWG®, DXF®, IGS, PRT®, DRW®, STP®, and CT® file formats.
  • Profile and I/O gaskets are available with a variety of pressuresensitive adhesive (PSA) tapes, including Easy Peel® with extrawide release liner to facilitate quick assembly.
  • Profile gaskets can be cut to specified lengths,kiss-cut on release liner, or mitered to formframe configurations.
  • Fabric-Over-Foam gaskets are RoHS compliant.
