The Platinum Tools 2039 Copper Foil Strips consist of a copper foil backing and conductive adhesive. The strips are supplied on removable paper sheets for easy handling. The copper foil strips are typically used as an EMI / RFI shielding for applications in the electronics industry, such as static charge draining, seaming shielded rooms, cable wrapping, and surface contact to non-solderable materials. These copper foil strips work perfectly with all the Platinum Tools Shielded RJ45 Connector and Shielded Keystone Jacks (both sold separately).
