Next-Gen EMI Gasket with UL 94 V-0 Flame Rating for Aerospace, EV & Defense Systems
Electromagnetic interference poses real risk in aerospace, automotive, medical, and defense electronics. This gasket system pairs a UL 94 V-0 flame-rated conductive silicone foam core with a conductive pressure-sensitive adhesive that bonds to metals, composites, and plastics — shielding and flame compliance in one die-cut part.
What the system delivers
The gasket combines a UL 94 V-0 flame-rated conductive silicone foam core with a conductive PSA, delivering up to 90 dB shielding effectiveness across the 10 MHz–3 GHz frequency range while sealing against dust and moisture.

Frequently asked questions
How much shielding does this gasket provide?
Up to 90 dB shielding effectiveness across the 10 MHz–3 GHz frequency range, with performance depending on compression and joint geometry.
Does the conductive PSA affect shielding?
The PSA is conductive, so it maintains the electrical path between the gasket and the substrate rather than insulating it — attachment without losing shielding continuity.
