Copper Tapes

Home/Copper Tapes


Our Copper Tapes consist of conductive copper substrate with single or double-sided conductive adhesive and release liners.

Diamond Coatings Copper Tapes can be used to seal gaps (RFI sensitive enclosures) and fix and seal indium tin oxide coated windows into apertures.

Copper Tapes Sizes

Standard sizes for both Aluminium & Copper tapes are:

6 , 12, 25 and 50mm widths are standard stock sizes (non standard widths are available upon request). All rolls are supplied in 20 Metre lengths.

Ease of use

• Ensure surface of application is dry and clean
• Ensure correct placement, as excellent adhesion may make removal and re-application difficult and could result in reduction of stated resistance
• Ensure full strength can be achieved by ensuring copper tapes are not exposed to excessive tension after bonding

Application Fields

Our copper tapes are suitable for applications including LCD monitors, PDA and PDP; duplicating machines, mobiles, portable PCs and varying other electronic equipment requiring EMI shielding.


Indoor Temperature 23 +/- 5ºC – Dry Place – Valid for 1 Year
