Conductive Fabric Tape With High Shielding Effectiveness for Aerospace and Defense Electronics

When the standard Ni/Cu tape isn't enough

There's a version of conductive fabric tape we ship only when a customer's spec sheet won't accept the standard nickel-over-copper build. It's the same 0.08 mm polyester taffeta, but plated with gold or silver instead of Ni/Cu — surface resistance under 0.02 Ω/sq, shielding effectiveness above 80 dB from 10 MHz to 40 GHz, and a contact resistance that stays flat over a 20-year service life instead of creeping up as nickel tarnishes. This is the build that ends up in avionics retrofits, ground-based radar shelters, satellite ground stations, and industrial control systems where a failed gasket means an outage you can't just reboot.

We'll be straight up front, because the aerospace and defense buyers we talk to read the marketing copy from other suppliers and close the page within ten seconds: this isn't an AS9100-certified, ITAR-controlled, mission-proven-on-fighter-jets SKU. We're a materials manufacturer based in Shenzhen, founded in 2011, with ISO 9001 / 14001 / QC 080000 / IATF 16949 and a magnetron sputtering line in Shandong that's been plating gold and silver onto fabric roll-to-roll since 2020. What we can do is ship you a high-shielding, lot-traceable fabric tape with full test reports — and we'll tell you honestly whether your program can use it or whether you need a tier-1 aerospace distributor.

When to step up to gold or silver

Gold plating for long-life corrosion resistance. Gold doesn't tarnish or oxidize, and the contact resistance stays flat over decades in coastal, high-humidity, or exhaust-adjacent atmospheres. This is the build for ground stations, shelter interiors, and any installation where the enclosure is opened once every five years. It's also the right call where sulfur-bearing air would eat a nickel or silver surface.

Silver plating for the highest conductivity. Silver gives the lowest surface resistance in our catalog — under 0.01 Ω/sq — but it tarnishes in sulfur-bearing air. We ship the silver build for shielded rooms, test enclosures, and indoor equipment where tarnishing isn't a field issue.

Ni/Cu (the black nickel build on another page) for everything else. That's what we ship 90% of the time. If your spec sheet doesn't require gold or silver, don't pay for it.

Where this build actually ships

We'll skip the generic "fighter jets, satellites, naval" list. These are the jobs we quote every week:

Ground-based radar and satellite ground stations. Shelter seams, equipment rack grounding, I/O cutouts. Outdoor installations in coastal or industrial atmospheres where nickel would corrode inside a service life shorter than the equipment itself.

Avionics retrofits and obsolescence support. When a legacy box needs an EMI gasket replacement and the original part number is long obsolesced, we ship gold-plated fabric tape that cuts to the original outline without a custom die — often as a first article for the retrofit program, not a production aerospace qualification.

Shielded rooms and test enclosures. Silver-plated tape seams the panels of a Faraday cage, wraps cable penetrations, and grounds door contacts. It's the same build you'd spec for an EMC pre-compliance lab.

Industrial control in harsh environments. VFD enclosures, mining equipment, offshore instrumentation, power-generation cabinets — anywhere the standard Ni/Cu tape would corrode before the equipment does.

Unmanned systems and ground support. Drones, ground-control stations, launch-pad support equipment, where weight matters and a lighter fabric tape beats a heavy metal shield.

What we can document

Aerospace and defense procurement teams ask for paperwork before they ask for samples. Here's what comes in the box:

Every lot ships with a surface-resistance test report, shielding-effectiveness data, and a material declaration.

We're ISO 9001 / 14001 / QC 080000; IATF 16949 for automotive-adjacent lots.

We can support AS9100-aligned customers with full lot traceability, even though we're not AS9100 certified site-wide.

We don't ship ITAR-controlled or USML-list material. If your program is on the Munitions List, we'll redirect you to a tier-1 distributor — no point in us wasting your qualification cycle.

Why Johan can offer this at all

We've been plating metal onto fabric roll-to-roll since 2020, when we became the first domestic supplier to run continuous gold and copper plating on a magnetron sputtering line in Shandong. That's not marketing copy — that plant is the reason we can offer gold-plated fabric tape at commercial prices instead of aerospace-distributor prices. The adhesive is coated on our Hunan line (10,000 m²), the slitting and die-cutting happen in Dongguan, and the lot-traceability file follows every roll from the plating run to the shipment.

Because we control the plating, the coating and the conversion, we can tweak the plating weight on a customer's spec rather than reselling a pre-plated Japanese or Korean roll.

Working with us

Standard widths slit from 3 mm to 500 mm; die-cut patches and custom outlines to your DXF. Gold or silver plating on request. First articles leave Dongguan in 7–10 working days.

Tell us the environment (coastal? sulfur? temperature range?), the required service life, and the shielding spec. We'll recommend Ni/Cu, silver or gold — and if you don't actually need gold, we'll tell you.

Sample rolls ship in 3–5 working days; production in 2–3 weeks.

Storage: 12 months at 18–26 °C, 45–65% RH, FIFO. For the silver-plated build, we pack in sulfur-free barrier bags so the roll doesn't tarnish on your shelf.

If your spec sheet calls for gold or silver plating and a multi-decade service life, send us the drawing. We'll tell you whether we can ship to your program's documentation requirements, or whether you genuinely need a tier-1 aerospace supplier — and we'd rather lose a quote than ship you a part that fails qualification.

If your program requires AS9100, MIL-spec qualification, or ITAR-controlled supply, tell us up front — we'll either support it with full documentation or redirect you to a tier-1 distributor rather than ship a part that fails qualification.
