Conductive fabric and foil EMI shielding tapes

Back to product list

General description

Conductive shielding tape offers excellent conductivity, conformability and durability in a thin, lightweight and flexible design.

Conductive Fabric Tapes

Our conductive fabric tape is based on a nickel over copper metallised synthetic textile yarn that is uniformly plated throughout its cross-section providing consistent low resistivity. Furthermore this arrangement ensures that this type of EMI shielding tape is particularly resistant to abrasion as ‘fresh’ plated fibres are continually exposed as the outer surface wears.

This type of EMI shielding gasket section has several advantages

• Good shielding performance – typically 90 – 110dB
• Extremely good wear characteristics
• Available with adhesive backing enabling easy fitting
• Tape construction provides extra flexibility
• Available in a wide range of sizes
• Non flammable to UL94-V0

This tape is typically available on 50m rolls 10-1000mm wide. 

Conductive Foil Tapes

We offer a range of conductive metal foil tapes that are suitable for many grounding and EMI shielding purposes. The range of tapes offered are based on three main foil types:

Aluminium
Copper
Tin plated copper

The copper and tinned copper tapes are readily solderable

Each type is available either with a conductive acrylic adhesive or without adhesive (plain foil). The adhesive backed versions can be wound on a release liner or self wound. They can all be supplied in widths up to 300mm, although more commonly supplied in widths of approximately 12, 25 and 50mm. All three tape types are very conformable allowing them to be applied to irregular or contoured surfaces. As such they are suitable for a wide range of EMI shielding and ESD control applications as outlined below:

• Improving the EMI shielding of sheet metalwork seams/joints
• Grounding ITO coated films for ESD protection of displays
• Terminating shielded windows and display back shields
• Creating shielded enclosures by lining plastic covers and enclosures
• Shielding of static cable assemblies / conduit
• General test and development work

We can supply pre-cut / formed components from these tapes so that they are easily assembled into or fitted into their intended location

In order to achieve the best possible electrical performance it is important that the surface it is to be applied to is not only clean but free of any oxidation /corrosion.

Electrically Conductive Tape Datasheets

	ECT-AL001 is a soft aluminium foil tape with a pressure sensitive conductive adhesive. It is particularly suited to applications such as cable shielding and EMI proofing seams in sheet metal cabinets.
	ECT ASMR001 is a conductive adhesive transfer tape that combines both conductive pressure sensitive silicone and acrylic adhesives on opposite sides of a conductive woven mesh interlayer.

	ECT ASMR002 is a conductive adhesive transfer tape that combines both conductive pressure sensitive silicone and acrylic adhesives on opposite sides of a conductive non woven mesh interlayer.
	ECT CNFR001 is a nickel over copper plated PET based rip-stop fabric tape with a pressure sensitive conductive adhesive. It is both extremely flexible and durable with a very high resistance to tearing.
