Z-3250-CN EMI shielding fabric is a .004-inch-thick, woven Nickel over copper-plated polyester taffeta cloth that provides outstanding EMI shielding performance. The thin-woven polyester construction makes Z-3250-CN extremely flexible, yet very strong, and provides excellent corrosion resistance and resistance to environmental degradation. It is, without doubt, the most versatile of all Zippertubing's EMI shielding products and can be incorporated with almost all of our jacketing products to provide a thin, lightweight and very flexible shield. The cloth has an electrical resistance of less than 0.1 ohm/square, provides shield coverage of approximately 98% and averages 85 dB of attenuation from 10 MHz to 20 GHz. This is Zippertubing's most popular shielding material.

A thin Acrylic transfer adhesive containing Silver plated Nickel particles making the material electrically conductive in the "Z" axis (i.e. through its thickness). This tape is not used as a mechanical closure for jacket materials, but rather as a filler between seams and layers of flexible EMI shielding cloth to insure a low electrical resistance joint. This adhesive will withstand moderate temperatures and has a low bond strength. Any seam joints using this material must be mechanically retained via sewing or other mechanical means.
