Z-3250-Tape™

EMI Shielding Tape, Ni/Cu/Polyester Fabric, Adhesive Backed

Z-3250-Tape™ is a conductive EMI Shielding Tape consisting of Zippertubing's Z-3250-CN EMI shielding fabric and an electrically conductive transfer adhesive backing. The adhesive eases installation and insures continuous continuity between individual coil winds. Use as a standalone shield in applications requiring a soft, thin, flexible and non-abrasive shield.

This product should be protected by a secondary insulation tape or jacket to protect the shield from damage. The tape allows joining of Z-Shield™, Shrink-N-Shield® and PRT™ (S) EMI Shielded jacket sections at cable splices, branch-outs, and transitions to connector hardware.

Z-3250-Tape™ provides excellent 98 percent electromagnetic shielding coverage when spirally wound with a 50% overlap (minimum). Z-3250-Tape™ standard tape width is 1.0 and 2.0 inch, while custom widths are available.

This product has an operational temperature range of -45° to 150°C (-49° to 302°F).
