EMI Shielding Tape, Polyurethane and Ni/Cu/Polyester Shield

ZT-Shield® (3250) is a combination of fire retardant Polyurethane ZT-Tape® stagger bonded to a layer of Z-3250-CN shielding fabric with an electrically conductive adhesive backing. When spirally wrapped around electrical wires or other items using a 50% overlap technique, this product will provide a finished installation with excellent electromagnetic shielding characteristics. This product features a shield coverage of 98 percent and a flame-retardant Polyurethane insulation jacket with good dielectric strength.

This tape eliminates the need to go back over a shielded assembly a second time to apply a protective dielectric insulator. ZT-Shield® (3250) also referred to as Shielded ZT-Tape® is available in multiple widths to accommodate most wire harness diameters.

This product has an operational temperature range of -50° to 80°C (-58° to 176°F).
