Engineered to shield
with precision

Combining Nickel and Copper woven metal fibers with a soft PU foam core, our EMI gaskets deliver consistent shielding performance across industrial, telecom, and medical environments.

From concept to assembly, we integrate low compression force design with abrasion-resistant fabric providing gaskets that maintain shielding effectiveness after over one million compression cycles. Supplied cut-to-length, ready for immediate production use.

Why Choose It

Six reasons engineers
trust our gaskets

Every feature is backed by rigorous testing at 70% humidity and 25°C, ensuring specifications hold in real-world installation and long-term cycling conditions.
Superior EMI Shielding
Ni/Cu woven metal fibers deliver shielding effectiveness exceeding 80 dB across the full 100 KHz to 1 GHz range — consistent across all standard test configurations.
1 Million Cycle Durability
Abrasion-resistant polyester fabric sustains over 1,000,000 compression cycles with virtually no degradation in shielding performance or surface conductivity.
Ultra-Low Impedance
Surface impedance of 0.05 Ω ensures excellent grounding and bonding performance, meeting tight EMC compliance requirements in commercial and military specifications.
Corrosion Resistant
Ni/Cu fiber composition provides outstanding oxidation resistance and galvanic compatibility across plated, anodized, and stainless-steel mating surfaces.
Low Compression Force
Soft PU foam core requires minimal closure force, enabling use with thin-gauge aluminum and plastic enclosure panels without warping or seal failure over time.
Dual Adhesive Options
Available with Conductive PSA (EMI grounding through adhesive) or Non-Conductive PSA (mechanical mounting), giving design engineers full flexibility.
Construction

How the gasket is built

01
PU Foam Core
A low-density polyurethane foam forms the core, providing compressibility and spring-back. Its softness allows effective sealing on irregular mating surfaces with minimal closure torque.
02
Ni/Cu Conductive Fabric Wrap
The foam is wrapped in an electrically conductive polyester fabric woven with Nickel and Copper metal fibers, creating a continuous conductive path between the gasket surface and enclosure walls.
03
PSA Adhesive Backing
A pressure sensitive adhesive is applied to one face. Choose Conductive PSA for through-adhesive grounding, or Non-Conductive PSA for standard mechanical mounting applications.
04
Cut-to-Length & Custom Shapes
Precision-cut to your specified length or shape — strips, die-cut frames, I/O port profiles — delivered ready for direct assembly on the production line. No secondary processing required.

FAQ

Common questions answered

Manufacturing
How do I specify the correct gasket size?
+
Provide the cross-section profile (width × height in mm), total length or perimeter, and whether the gasket needs to form a closed frame or open strip. Our team will confirm the fit and suggest compression ratios for your enclosure closure force.
What is the difference between Conductive and Non-Conductive PSA?
+
Conductive PSA allows current to flow through the adhesive layer itself, enabling EMI grounding even when the gasket is bonded to a non-metallic surface. Non-Conductive PSA is used for pure mechanical fixation where grounding is achieved via compression of the fabric face to the mating metal surface.
Are custom shapes and die-cuts available?
+
Yes. We supply custom die-cut frames, I/O port profiles, angled corners, and complex perimeter shapes. Share your DXF or drawing and we will confirm lead time and minimum order quantities.
Do you offer halogen-free variants?
+
Yes, halogen-free products are available on request — preferred for medical, automotive, and environmentally sensitive applications where strict material declarations are required.
What surfaces are the gaskets compatible with?
+
The Ni/Cu fiber construction is galvanically compatible with zinc-plated, chromate-treated, stainless steel, nickel-plated, and anodized aluminum surfaces. Please consult us for use on magnesium or bare aluminum where long-term galvanic effects may need evaluation.
